[solved] -MP

[Ascor]

... a mp: 40 (or whatever but don't use - it will give the enemy mp)

Ehm...he means that the enemy loses mp when attacked, not gains mp.
You have to make special frames in each character where he loses a specific amount of mp.
Then make a catch_run thing in your attack where the catchingact: will lead to those frames.
So when you attack, the move will catch the enemy and bring him to the frames where he loses mana.
