Hint: Easy win in final battle: To perform this trick, each member of your party in
the final battle should be at Level 60 or higher, and you need
either Nazha or the Bird to be in the battle (preferably both).
In the first turn, move up and to your right to destroy the first
tentacle. Make sure to go right -- the Fire Cats on the left
only drop Healing Seeds, and it is pointless to kill the left
tentacles first. Use your most powerful magic and make sure you
attack him only after he makes his turn. Do not move into his
magic range before. In the next turn, move more to your right
and up, and let someone who has a free item space kill the Fire
Cat so that you can take his Magic Mushroom. In the next turn,
kill the tentacle in exactly the same way as you did the last
time. Kill the Fire Cat to get his mushroom, and use it on someone
to replace magic used to kill the tentacle. Repeat this until
all four tentacles on the right side are killed. You may have
noticed that the Boss Head casts a blue streak spell down the
path of entry to him every three turns, regardless of whether
you are on the path or not. It costs him magic; all you have to
do is wait until his magic is down very low from doing this and
kill the occasional Fire Cat that comes along. When the Boss Head's
magic is close to zero, use Nazha and the Bird to come within
three spaces and cast powerful magic on him. When they run out
of magic, use magic mushrooms. When the first form of the Boss
is killed, run away and let him use his magic up by casting his
spell. When he has, return to him and kill him the same way you
did last time. Make sure you do not make a mistake and come into
contact with the left tentacles, as they can cast a powerful Lightning
Spell on you.
