Every skill has a different formula. Usually it's the attacker's ATK or MAG, times a multiplier, minus the defender's DEF or MDF, times a usually smaller multiplier. Sometimes a small flat amount is added or there's something more complicated.

Evasion and critical hits are flat chances, which are the same for most characters and modified only by a small number of things like Aka's special knife. Some skills hit automatically and cannot miss or be evaded. Some skills, mostly magical ones, cannot crit.
