I found out that you cannot change Vincent's limit's animation, as his first limit will always be Galian Beast, the second will always be Death Gigas, ect, but if I use liBrE to tell him not to "lose control and transform into monster [m]" he will be fully controllable, and still turn into a Monster.
The problem is that the "monster" does not have an attack, or a magic animation, so I you do anything, the game hangs for a minute, he appears in front of the enemy, deals damage, hangs for another minute, then ends his turn.
I know the **da file holds the battle animations for the models, but is it possible to edit(I assume that means hex-edit) the file so that attacks are given the transformation's primary attack animation, and magic attacks show its secondary attack animation.
