Multislice is learned when one advances to Rank 4 of the Gladiator vocation. It hits all enemies for damage, which starts at 100%, and decreases to 80%, 70%, & 50%. Terry uses this skill when he is fought as an enemy, and Demonriders, Sintaurs, & Octavian sentries can also use it in battle.
Multislice is learned through a variety of vocations in VII, such as rank 7 of the Gladiator, rank 2 of the Champion, rank 8 of the Mandrake Major, rank 6 of the Berserker, and rank 3 of the Slaughtomaton. It acts the same as in VI, but in the 3DS remake, it costs 3 MP to use, and is also used by Automatons.
