Defeating higher level Dual Horns

In later missions you may encounter Dual Horns called Diceratops or Grand Horn. The Diceratops has Null Magic, so you must use physical attacks, but the Grand Horn is very difficult. It has Null Magic and Null Physical, requiring you to wait for the DMW to get you a combination. Your best bet is to buy Zantetsuken Materia and level it up to the maximum. Also, buy a Lucky Stars Materia, as the Grand Horn has an attack called Gaia's Wrath which will lower your limit level. You cannot control this one at all, so patience is key. You can steal a Pearl Necklace (rare steal) from it.

Easy criticals

To hit easier criticals, run behind any enemy and make sure to attack from behind. Note: Some enemies might take criticals from the sides.
