Characters can deal more damage with offensive Ninjutsu by using the Focus ability, as well as raising the character's INT (this includes the INT+20% ability). The damage value is unaffected by rows when casting Ninjutsu skills. Equipment does not affect damage calculation of Ninjutsu, unless the weapon or armor increases the character's INT. The formula for health restoration by use of supportive Ninjutsu is unaffected by the MND stat, as the skill is based on a percentage value of the target's HP.
