Defeating Gi Nattak

• The Gi Tribe Boss under Cosmo Canyon is an undead creature. Cure items such as X-Potion or Phoenix Down work against him. Note: Phoenix Downs can miss, but and X-Potions will always be effective.
  , , , , and

• Make sure that you have at least 4 Phoenix Downs in stock. At the beginning of the fight, select a Phoenix Down and use it on the Nattak himself, not his henchmen. It should say instant death and he should die without a battle. If it misses, keep trying.
  

• When you fight Gi in Cosmo Canyon cave, use a X-potion or Elixir To kill him instantly.
  

• Save the X-potions you receive early in the game. When you face Gi Nattak in the caves at Cosmo Canyon, use one X-Potion on Gi Nattak. Because he is weak against Holy and X-Potions replenish all health, it does the opposite to Gi Nattak and results in an instant kill.
  

Defeating Sephiroth

• When you battle Sephiroth the first time, just use Knights of the Round to immediately win. Even though one of his five parts does not take any damage, he cannot live without it. When you battle the second Sephiroth, use Knights of the Round, then Mime Knights of the Round. Now have another character use Bahamut Zero. This should kill him. When you fight the third Sephiroth, use Omnislash.(Cloud's Level 4 Limit). Even if you only have the Level 3 Limits, the game will allow you to use it. After this, Sephiroth will die for the final time.
  

• For Sephiroth Bizzaro, use Knights of the Round. On Safer Sephiroth, use De-Barrier then use Knights Of The Round. On the last form, your limit should fill allowing you to use OmniSlash.
  

• When you are fighting Sephiroth at the end of the game with only Cloud, if he is level 99 and have Omnislash, one attack will kill him.
  

Defeating Bizzaro Sephiroth

• Cast one Mastered Knights Of The Round for a one hit Bizzaro Sephiroth battle.
  

• Before fighting Bizzaro Sephiroth (after the last piece of Jenova), put the Slash All Materia on your strongest attacker. That way, they can attack all five parts at once and quickly eliminate him.
  

Defeating Safer Sephiroth

• A Mime Materia and a mastered Knights Of The Round summon materia is required for this trick. First, cast Knights Of The Round with one character and then use mime with another character. Savior Sephiroth should be defeated in those two hits.
  

• You will need to have W-Summon, Knights Of Round summon, Mime command, and Quadra Magic. Master Knights Of Round. Equip this with Quadra Magic and W-Summon on Cloud. Equip Mime on another character. This trick will have to be repeated if the other character does not attack immediately after Cloud. Use W-Summon Knights Of Round two times and he will use it eight times. Quadra Magic must be at second level. Then, use Mime and your other character will use it eight times.
  

• Put the Enemy Skill Materia (can be found in the Green Chocobo's stable at the Chocobo Sage's house) on your best magic-using character. Put the Long Range Materia (found after defeating the Materia Keeper in Mt. Nibel) on your best attacker. When Sephiroth uses his Shadow Flare attack, whoever has the enemy skill Materia will learn it. Then, cast it on him only when he floats up in the air (to conserve MP). Make sure whoever you put the Long Range Materia on does not already have a long range weapon (for example, Vincent or Barret), or it would be pointless. Put it on your best attacker so that they can damage him even when he is floating.
  

• Have two characters in your part have Mime, and the other with W-Summon connected to Quadra magic . This will allow you to use any magic or summon six times in a row. Have the two people with Mime use it, then have the last one use Knights Of The Round on him. This will result in eighteen consecutive Knights Of The Round hits. Heal your HP and MP, and repeat the summoning. Note: This will not be an instant killer.
  

Defeating Ultimate Sephiroth

After defeating Bizzaro Sephiroth, you probably will not have much ammunition left unless you were wise and only used physical attacks, healing items and limit breaks during that fight. Ultimate Sephiroth is stronger, faster, and ultimately more powerful than his previous counter parts. Cast Knights Of The Round summon just once and get another member of the team to Mime it, making sure not to make any moves in-between commanding that person to mime the action. If any members of your team are injured, cure them with a Megalixer or some other healing potion before the battle starts. Sephiroth will cast Shadow Flare or Pale Horse on one of your team members. Do not worry about this and just continue the fight. Attack him physically once, preferably with Cloud or Cid as they are the strongest. Sephiroth should be defeated. Note: If you wait too long, Sephiroth will cast Super Nova or Pale Horse.

Defeating Jenova Life

• Equip one person in your party with a Dragon Armlet and Water Ring. This will make Blue Light and Blue Flame do half the damage and Aqualung cures that person.
  

• Equip the Aurora Armlet (which you can find nearby) to your hardest hitter. Un-equip every Materia you have on that person. When you start the battle, use as many summons as possible before he casts some sort of barrier. That barrier will deflect magic that you cast on him. Then, just keep using attacks or D. Blows on him. By now your other teammates will be dead. Do not revive them. Notice that everything Jenova does to hit you will just revive your health. Keep doing Attacks or D. Blows until you win. Note: Once the screen reads "Jonova-LIFE's skill power is used up", you can revive your partners because he will not attack.
  

Defeating: Materia Keeper

When fighting the Materia Keeper, he will most likely kill all of your other fighters first, leaving only Cloud. Cast Regen on Cloud and keep using Cures to heal him after the Materia Keeper uses his strong attacks such "Hell Combo" and "Trine". Cloud will fill his Limit Break bar. Use the Limit Breaks and keep repeating until the Materia Keeper has been defeated.

Defeating the Midgar Zolom

Have Barret in your party with Fury on. The Midgar Zolom will give him a Limit Break in one hit. Have Barret on the bottom of your menu and all characters in the back row. Use the other characters to heal and use Barret's first Limit Break as Mindblow. This will zap the Zolom's magic, away rendering Beta useless. Also, if your characters have Sadness level 26, Zolom will only do 900 damage at maximum with Beta. Beta is also an Enemy Skill. Zap his energy, use Bio, and defeat him.

Avoiding the Midgar Zolom

When you must cross the marsh near the Chocobo Ranch, you are supposed to get a Chocobo. Get whatever you want from the ranch, then position yourself as far out into the marsh without actually stepping in it. Wait until the snake goes way off to the left and run straight across without looking back. You should make it in the nick of time. Note: Save before attempting this, as it may require more than one attempt.

Defeating Reno

To defeat Reno and his bodyguard (the Turks) when you fight them for the first time, make sure that you heal all the time. Free your trapped comrades from his "Pyramid". Defeat his bodyguard first, then go after Reno.

Defeating Techno Soldier

When fighting Techno Soldier near the beginning of Disc 1, attack him in the back and use Bolt. This will easily deal over 1,000 HP of damage if timed correctly. It is best give either Tifa or Barret Bolt so that both can attack while using the back attack strategy.

Defeating Ultimate Weapon

During Disc 3, find the Ultimate Weapon hovering over a lake. Defeat it and it will retreat as before. If you happen to find it hovering around the ocean, run in to it. This will make it find a new place to destroy. Defeat it each time you see it hovering over one place. The final battle with it will take place over Cosmo Canyon. After you defeat it there, it will crash to the ground. This will give you access to the Antiant Forest and Cloud's Ultimate Weapon.

Stealing from Ultima Weapon

It will be useful if you have "Steal as Well" and "Comet" (Comet2) Materia linked together, and the "Steal Glove" accessory equipped. After defeating the Diamond Weapon who is approaching Midgar, wait until the entire storyline finishes so that you may control the Highwind Ship again. When you fly the ship, it is important that you not go to Midgar or you will have to do this trick on the Disc 3. Otherwise, you can wait later if you are not up stealing Ultima's items. Fly the ship where there is a circle-like waterfall behind Junon. Ultima Weapon is hovering over the waterfall. Engage in battle and use Comet2 on Ultima. You will steal a Circlet accessory which upgrades your Magic and Spirit by +30. You can only get it when Ultima is hovering in battle. When he is on ground, you can steal Reflect Ring accessories. If you are on the Highwind and encounter him when he is flying around, bump into him five times; he will fly, then stop and charge up a blue energy ball over the area he is at. Be careful that he does not stop over Midgar or you will have to finish collecting his items on the Disc 3. Note: When you encounter Ultima Weapon for the first time, you can steal a Cursed Ring accessory which raises increases your status but it also induces Death Sentence on yourself; it is best that you have "Added Effect" and "Destruct" Materia linked together if you plan on using it.

Defeating Demons Gate

• Physical Attacks work really well against this opponent, especially if you have Cid equipped with Trident in your group.
  

• After your battle with Red Dragon.Go to go to your menu screen and select "Marteria". Take all your Materia off except for All Materia, Restore, Barrier, Time, and Deathblow. If you want your summons keep those Materia equipped. The Materia is taken off becuase your health points will go up. Keeping Restore allows you to heal your party.Make sure to have at least one All Materia equipped, and have it in a double slot with either Restore (recommended), Barrier, or Time. Keeping Barrier equipped will allow you to cut off some damage that Demon Gate has sends. Keeping Time equipped will allow you to cast the spell Haste. Deathblow will either have a critical hit or a miss. Remember that Demon Gate has a high magic defense.
  

Head Hunters

To fight head hunters, go to the Mideel Forest and walk in the dark grass.

Red Gagighandi

Go to the Temple Of The Ancients and find the small dark area, similar to what is around Midgar, near the beach. Walk around the area and you will eventually encounter the Red Gagighandi.

Rilfsak

While in the Ancient Forest, you will encounter the Rilfsak. Most of the time physical attacks will not harm it. However, 50% of the time Mug should hurt it. Note: You can use magic attacks. There is nothing to steal from it.

Master Tonberry's Everyone's Grudge attack

In the Northern Cave you will encounter an enemy called Master Tonberry. His attack called Everyone's Grudge can appear very strong. However, there is a pattern to it. For every enemy a character defeats, Everyone's Grudge damage increases by 10. For example, if Cloud has killed 600 enemies, Everyone's Grudge will hit Cloud for 6000 HP. This pattern is based on individual characters only.

Defeating Ruby Weapon

• Kill two members of your party before fighting Ruby Weapon. Have the Summon Phoenix materia equipped on the remaining character, then run into Ruby Weapon. When fighting, Ruby will only attack the live character, and therefore not use the Quicksand attack. Wait until the Weapon sticks his claws in the ground. Then, use Summon Phoenix to attack it and revive the dead party members. All three party members are now available for the battle.
  and

• Another strategy is to have all characters equipped with the Final Attack + Revive or Phoenix materia combination. Have one character equipped with a weapon or armor containing Knights Of The Round + MP Turbo. Also have a Mastered Magic Plus materia (not MP Plus) somewhere else in the weapon or armor of each character. Have all three people wear the Mystile armor (first from Midgar Raid, second from North Cave, third from Ultimate Weapon when it is over Midgar). This will prevent Ruby's Ultima attack from injuring your characters. Kill two characters, then enter the battle with Ruby Weapon. When the Weapon's claws are in the ground, revive the two dead characters, and have W-Summon cast Knights Of The Round and have the other two characters Mime. This will hit Ruby Weapon for 9999 damage each time. It should be defeated after eight to ten rounds of this type of attack.
  

• Another strategy is to kill two of your characters, then equip the following materia combination: HP Absorb + Knights Of The Round, W-Summon, Mime. Use a Hero drink, then summon the Knights Of The Round. Each time he/she will gain over 9,000 HP points. Then, simply Mime this attack until the Weapon is defeated.
  

• Another strategy is to use Mime in addition to the Final Attack + Phoenix materia combination. Get Cloud's limit bar full, and start the battle. Ruby will take your other two characters away with Quicksand. Attack with Omnislash. At Cloud's next turn, select Mimic and Cloud will use the Omnislash again. Repeat this attack. The only drawback to this strategy, is the need for a little bit in the limit meter. Without it, Cloud will jump forward after a brief flash, and Ruby Weapon will attack. When Cloud does the limit, the game will act as though you had a full limit bar, and delete all that remains in it. To effectively make this trick work, make sure Ruby Weapon hits Cloud before doing the Omnislash again.
  

• Another strategy is to have Cloud alive with maximum HP and MP while your other two characters are dead. Have mastered Counter Materia (not Counter-Attack Materia) paired with Mime; Knights Of The Round paired with HP Absorb; enough HP and defense to avoid getting killed in one hit; a high Magic rating (200+); and a Ribbon. Cast Knights of the Round and every time Cloud gets hit he will counter with that attack. Cast Knights of the Round and then use Mime as fast as possible.
  

• Another slightly different strategy is to get the following Materia for Cloud: Mastered Command Counter paired with Mime (not the Counter-Attack Materia, . the Command Counter is a blue Materia), Knights Of The Round paired with HP Absorb, enough HP and defense, high magic rating (200+, best achieved with Magic Plus mastered), a Ribbon, two Knights of the Rounds Summons, W-Summon, Master Summon paired with MP Turbo (on different slots than the regular Knights Of The Round slot). Before start the battle, intentionally kill your other two party members. When you start the fight, simply cast Knights of the Round (W-Summon or without) on Ruby Weapon. Every time Cloud gets hit, he will automatically counter with Knights Of The Round and regain HP.
  

• Equip the Enhance Sword or Ultimate Weapon, Mystile, and Ribbon on Cloud. Link a mastered Final Attack to Revive, link Knights Of The Round to Hp Absorb, Hades to Added Affect Magic Plus (if you have one), enough HP and MP Plusses to max out those stats, and anything else all on Cloud if space permits. For the other two characters, equip HP and MP Plusses, a Mime, and anything else. Before the battle have Cloud kill the other two characters. Get in the Highwind and fly into his Ruby Weapon's head sticking out of the desert by Gold Saucer. As soon as you start he will plant his claws into the ground. You should cast Hades straight away, this will stop him and his claws allowing you to cast Knights Of The Round once and revive the other two characters. As soon as it is Cloud's turn again, cast Hades and Ruby Weapon will be stopped again. Cast King Of The Round and Mime once, then cast Hades again and keep repeating until it is defeated.
  

• Create a party of your strongest characters. Equip them with the Mystile. Leave one character alive, preferably Cloud. This character should have the best Materia. He/she should have a Final Attack linked with Revive and a Mega-All each at the Master level. When entering the battle, since only one character is standing, Ruby will only use a physical attack then bury its stalks. Now, cast Life 2. All your characters will be restored. Be careful, as at a point in the battle Ruby Weapon will reveal her stalks and use her Whirlsand attack. Knights of the Round is effective during this battle, even though Ruby Weapon will counter with Ultima. You will have a 60% chance of dodging it, due to the Mystile.
  

• Note: This trick can be used against Ruby or Emerald Weapon. Have Cait Sith go into battle with a limit break, and make his level 2 limit, Slots, has been unlocked. Once in battle, press Square (PlayStation version) when his slot reels appear to slow them down and get the combination that instantly kills any enemy. If done correctly, the Weapon will die.
  

• Ruby Weapon can absorb almost all types of magic.
  

• This trick requires need Cloud's Omnislash, W-Summon, Knights Of The Round, HP Absorb, and Mime. Equip Mime, Knights Of The Round (with HP Absorb), and W-Summon on Cloud, then get his Limit Break up. Kill both of the other party members then save the game just before Ruby Weapon. Start the battle by attacking his fingers with Omnislash. He will pull them back out, then put them back in. Next, use Mime to use Omnislash again on his fingers. Repeat this one more time. After he attacks you, use W-Summon and Knights Of The Round. You have HP Absorb because when he attacks you will lose a lot of HP. After summoning Knights Of The Round, you will gain your health back. After the second summon, he will attack you again. Use mime and you will do Knights Of The Round twice and regain health. Repeat this about four to five times and Ruby Weapon will be defeated at about the seventh or eighth Knights Of The Round attack.
  

• This trick requires Final Attack, Phoenix, Knights Of The Round, HP Absorb, W-Summon, Omnislash (optional), and Mime (mastered at least once). Start the battle with Ruby Weapon sticking his fingers in the ground. Once they are in, use Phoenix to revive your other party members. Then, use Knights Of The Round (W-Summon; with HP Absorb equipped together).Once it is done, use your other characters that have Mime equipped to summon Knights Of The Round (W-Summon) on Ruby Weapon. You will need Phoenix and Final Attack equipped in case you die.
  

• Fire and Elemental on your armor both at Master can help, as Ruby Flame will heal you by about 2,000. shields are a bit more of a necessity for this, as the two tentacles will not be able to cause damage or status abnormalities through it. Keep at him with Quadra Magic, Knights Of The Round, W-Magic combination. Also, enemy skills are helpful. To be safe, have Revive and Final Attack both at Master. If you keep your shield up and ignore the tentacles, Ruby Weapon will be vulnerable to attack. Keep at him with Knights Of The Round and also have an Omnislash ready before starting the fight. If you run out of MP, another Knights Of The Round put with Mp Absorb will fix that. If this is not possible put x4 Slash on and use it. However, it is well worth obtaining some Turbo Ethers beforehand and Megalixers just keep your shield up by checking status in the fight
  

• Note: To use this strategy it is recommended that you first defeat Emerald Weapon to get the Master Materias. Take your strongest character and equip him with the following W-Summon, Master Summon coupled with an HP Absorb, a master level HP Plus (use as many as necessary to raise your HP to 9999), and a master level Magic Plus (use as many as necessary to raise the characters Magic to 255). Before entering battle with Ruby, kill the other two characters in the party. If this is not done, Ruby Weapon may randomly kill off the character with the Materia setup. Upon entering the battle, use W-Summoned Knights of the Round. Because there are thirteen knights, assuming that each does at least 8,000 damage, they are summed twice in a turn, and that there are five turns, you will do 1,040,000 points of damage to Ruby.
  

• Make sure to have the following Knights Of The Round (mastered), three Mimes (two must be mastered), Hades (mastered), Phoenix, and W-Summon. Before entering combat with Ruby Weapon, go into a low level area nearby and kill two of your party members. Make sure the remaining party member flees from combat (or kills your opponents), and that they are armed with the Phoenix Materia. Then, initiate combat with Ruby Weapon. Ruby will bury his claws immediately. Summon Phoenix and the first chance you get, use Hades on Ruby Weapon. This will paralyze him. The higher your level of mastery with Hades, the longer he will remain paralyzed. You can now W-Summon Knights Of The Round and have your other two party members Mime it. Usually Ruby Weapon retaliates with Ultima when this is done but, when paralyzed he cannot. This provides a much easier and faster way of defeating Ruby Weapon than the established Quadra Magic Bahamut Zero - Mime technique, as Knights of the Round deals far more damage and when Hades is used Ruby Weapon cannot fight back.
  

• Have Cloud at level 99, Barret at level 99, and Yuffie at level 69 or higher. Have the following attached to each character.

Cloud

Weapon: Ultimate

Armor: Mystile

Accessory: Jem Ring

Materia: HP Plus Mastered, MP Plus mastered, All and Restore mastered junctioned, All and Revive mastered junctioned, all and Destruct mastered junctioned, MP Turbo mastered junctioned to Master Summon, Mega All mastered, Enemy Skill preferable with White Wind and Angel Whisper learned, Chocobo Lure mastered.

Barret

Weapon: Ultimate

Armor: Aegis Armlet

Accessory: Jem Ring

Materia: HP Plus mastered, Double Cut mastered. All Restore mastered, All Revive mastered, MP Plus mastered, Master Command, Ultima, Shield, Full Cure, and Contain all mastered.

Yuffie

Weapon: Ultimate

Armor: Mystile

Accessory: Touph Ring

Materia: All Master Magic, 2X HP Plus mastered, Counter Attack MP Plus mastered, Magic Plus and Luck Plus mastered, W-item, Double Cut mastered, W-magic Alexander, Hades, Bahamut Zero all mastered.

Make sure you go into battle with two people dead and immediately bring them back. Summon Hades to freeze Ruby Weapon while you have Cloud summon a turboed Knights Of The Round. It should hit for 9999 damage for every knight. You will know it is working if Lancelot (the first attacker) hits for maximum damage. Heal when needed and have Regen constantly cast. Always keep your health and MP up during the fight.

Ruby Weapon reward

After defeating Ruby, you will get the Desert Rose. Take this to the Kalm traveler and you will receive a Gold Chocobo.

Full Ruby Weapon appearance

Ride a Gold Chocobo or Highwind and bump the red object near Gold Saucer. Then, escape the battle.

Defeating Emerald Weapon

• Equip a member of your party with a Gravity materia, at any level. It will hit the Emerald Weapon for 9,999 damage. Using this and the Quad-Magic combo can take almost 40,000 hit points from one attack round alone.
  

• Another strategy is to equip the following materia combination: HP Absorb + Knights Of The Round, W-summon, Mime, Underwater (and nothing else). Use a Hero drink, then summon the Knights Of The Round. Each time he/she will gain over 9,000 HP points. Then, simply Mime this attack until the Weapon is defeated. Keep your materia number as low as possible -- the more materia equipped, the more the Weapon's Air Tam Stomp will effect the party. For example, if four materia are equipped the Air Tam Stomp will take off 4444 HP points, five materia will result in 5555 HP points and so on.
  

• Enter the battle against Emerald Weapon and have a character equipped with a Gravity materia, and all characters with a Reflect Ring. Cast Demi 3 onto your characters with Quadra magic and W-Magic. Since each attack will hit with 9999 damage, a total of about 40,000 damage will be done due to the Quadra Magic. With the W-Magic, it will hit almost 80,000 damage. Finally, because it was cast upon all three of characters and reflected, it will hit Emerald Weapon a total of three times.
  

• Place Cloud, Red XIII, and Tifa in your party. Get their ultimate weapons and level 4 limit breaks. Build them to level 85 to 90. Equip Knights Of The Round and MP Absorb on Cloud, Phoenix-Final Revive on Red XIII and Full Cure, Comet and some HP pluses on Tifa. Build their limit to full. Run into Emerald Weapon with the submarine and have Cloud use Omnishlash and every one else use their limit breaks. Cast Knights Of The Round, and if you are low on HP, cast Full Cure. Emerald Weapon has approximately 700,000 HP.
  

• First, go to the forest outside the burnt Mako reactor and fight some Frogs. Use Mini on them and then Manipulate them. Get them to make the last two digits of your life on all characters to "77". However, this life total must be below 7777. Heal yourself so as your life totals on each of your three characters equals 7777. Equip one of your characters with W-Summon and Knights of the Round. Equip everyone with Mime materia. Fight Emerald Weapon, and at the beginning each character should hit Emerald up for 7777 for a long time. Just have one character cast Knights of the Round twice and then have the other two characters Mime that. After six Knights of the Round summons, Emerald Weapon be defeated. That way, only one character takes about 6000 damage and nobody else takes any damage.
  

• When fighting the Emerald Weapon, make sure one of your characters has only two materia equiped and has 9999 HP. When Emerald Weapon attacks with it's Air Tam Storm attack (which does 1111 damage for each materia equiped to that character), it will result in 2222 damage to that character, leaving him/her with 7777 HP and the Lucky 7777 bonus.
  , , and

• Get the Final Attack materia from the Battle Arena at Gold Saucer and win the special battle (accessible when Cloud has both the Level 4 Limit Break "Omnislash" and W-Summon materia). Link the Final Attack to the Phoenix summon materia. When that character dies, it will revive him/her and any other fallen allies. This is very useful in countering Emerald Weapon's attack if it does 9999 damage to all your characters.
  

• Emerald Weapon has 1,000,000 HP.
  

• Emerald Weapon's beam attacks are magic based. If you cast Wall you can cut his beam attacks in half and also reduce the damage from his stomp attacks.
  

• Use Vincent's third Limit Break (Hellmasker). The Nightmare attack it uses will sometimes cast Stop on Emerald.
  

• Have Cait Sith with his Slots limit break. Save the game just before you fight him with Cait Sith's limit bar full. Start the battle and use the Slots limit break until it ends up with something that resembles Cait Sith. Use it on Emerald Weapon to defeat it with one hit.
  

• First, equip the best of all equipment that you have. It does not matter if you can get AP with it or not. Then, equip an HP Plus Materia to each of your characters so that you have 9999 HP on them. Then, equip some sort of curing Materia to each one. Note: Only equip one of each. When the battle begins, use lots of defense and all the curing spells you need. Just survive for awhile with your Limit Breaks. Eventually, Emerald Weapon will attack with a skill that does 1111 damage for each piece of Materia you have equipped. When this happens because your party was at full HP when they will now have 7777 HP and will be able to do the lucky sevens attacks.
  

• This requires the Underwater Materia, Mime, Knights Of The Round, HP Absorb and a few Mastered HP Plus (as many as needed to get 9m999 HP). On one character, put Mime and all the HP Plus. On another character, put Knights Of The Round and in an attached slot, put HP Absorb. On your last character, put the Underwater Materia. Start with Knights Of The Round, then Mime it for the remainder of the fight. Make sure that the character with Mime does not have more then five Materias equipped because Emerald has an attack that deals 1111 times the amount of Materia, it is usually used immediately after another attack. Using Knights of the Round with HP Absorb should allow your character to heal about 8,000 HP each time he or she uses it. Just continue miming and make sure never to use other attacks and this fight should be easy. Afterwards, bring the Earth Harp to the man in Kalm to receive a full set of Master Materia.
  

• Notice that as your health deteriorates, so does the attack power of the Cloud's blade. Use Gravity + Elemental Materia both at Master on your weapon. This can be a great help, as even if your health is low you can still do a hefty chunk of damage as well. Revive + Final Attack, and the enemy skills Angel Whisper, White Wind, and Big Guard are also useful, as well as Knights Of The Round and Counter Magic. Keep hammering away until he dies (this is all assuming you have the Underwater Materia).
  

• Use the following trick to get All 7's Fever for the battle. It requires 9999 max HP. Have the character to get All 7's Fever equip only two Materias. One must be HP Plus and other is your choice. Fight Emerald Weapon. When you do enough damage to it (when his emeralds shut down), it will use Aire Tam Storm which does 1111 damage for each Materia on character. Your character should now have All 7's Fever. Note: This can be done for all characters, but the effect is not cumulative.
  Nova Akropol.

• Note: This trick requires a lot of patience and luck. First, you will need to have the following: Underwater (Independent), HP Absorb (Support), Knights of The Round (level 2 or higher), HP Plus (Mastered), Mime (Command), Counter (Support-- not Counter Attack), and W-Summon (Command). Link Knights of the Round to HP Absorb and Mime to Counter. Hopefully your HP is above 5000 at this point (being at level 60 or higher is recommended). Ride your Highwind to Junon and get into a random battle. Kill two of your characters, leaving the one with the highest Magic Attack stats. Equip a Mystile and Sprint Shoes to him or her. Take your submarine underwater. Look around and you should see Emerald Weapon either standing in a crater, in a seaweed garden, or moving around. If you cannot find it anywhere, go back up to the surface and submerge underwater once more. Collide the sub into Emerald Weapon and the battle will begin. With the Sprint Shoes, your character will always be in Haste. However, Emerald Weapon will always attack first. Your "wait" gauge will still be filling while it is attacking. Select W-Summon and choose Knights Of The Round both times. When Emerald Weapon hits you, a bar at the top of the screen will say "<name> has made a useless imitation". This indicates that your that Counter/Mime is working. As your character is casting Knights Of The Round, it will appear as if he or she is casting it four times instead of two. Also, Knights Of The Round will restore your HP, because of the linked HP absorb to Knights Of The Round. However, do not just wait for Emerald to attack. When the Summon sequence(s) are finished, allow your wait gauge to fill and select Mime. Emerald Weapon will hit you again, making you cast Knights Of The Round two times, due to Miming the W-Summon you had made earlier in the battle. Also, your Mime will work, casting Knights Of The Round two more times. When Emerald's "eyes" open, it will execute an attack called "Emerald Beam". It hits you, causing you to counter, casting Mime, which you are actually casting Knights Of The Round again, for a total of four more summons. However, Emerald Weapon will interrupt your summon sequences by countering with Revenge Stamp, which will hurt your HP by slightly less than half. Emerald will also execute an attack called "Aire Tam Storm". You should have at least seven Materia Orbs on your Weapon/Armor. This attack will inflict at least 7777 damage to your HP, possibly killing you. However, there is a 33% chance that this attack can miss. To help, tap L1 + R1. If the attack misses, the eyes will die and you will continue to cast Knights Of The Round until either it stops or Emerald Weapons dies.
  

• First, equip Cloud with a weapon and armor that gives him maximum Materia capability, although they must be linked. After that, fill all of the Materia slots with a Counter Materia linked to a Mime Materia. Then, build up Cloud's Limit Break and go to battle Emerald Weapon. Use a character other than Cloud to give him a Hero Potion. Use Cloud's Omnislash and wait until he gets hit. This will result in Cloud counter-attacking with his Limit Break for a number of times equal to the number of Materia you put the Counter Materia on him. For faster results, you may use Barrett.
  

Emerald Weapon: Aire Tam attack

Emerald Weapon's "Aire Tam" Storm attack is "Materia" spelled backwards. This is also a clue to how it hurts your characters. The more Materia you have, the higher the damage. For example, if you have four Materia orbs on Cloud then the "Aire Tam" Storm will hit for 4444 points of damage.

Emerald Weapon reward

After defeating Emerald Weapon, you will get the Earth Harp. Take this to the Kalm traveler to receive master Summon, Magic, and master Command.

Temple Of Ancients Boss: Aeris and Odin

While in the Temple Of Ancients with Aeris, equip Odin on her. If you are facing the Boss, then equip it on another character. Doing this doing will result in a Steel Bladed Sword (Odin's best attack that automatically kills enemies if it hits them) in every normal battle.
