  • Despite saying that the skill increases Magic by 6 during combat, it will, unlike other magic-boosting skills, increase Magic above the game's 99 stat cap. This means the skill is effectively +6 Atk during combat rather than +6 Mag since there are no effects in game which check for the increased magic during and only during combat besides the damage dealt.
