  • The stat increase that can be applied by Atk/Res Gap is considered a  bonus.
    • Any 【Bonus】 on a unit lasts until the start of that unit's next phase.
    • If  bonuses are acquired during the enemy phase, they will disappear when the next player phase begins.
  • Atk/Res Gap does not compare Atk+Res total stats.
    • Because no comparison is made, skills like Phantom Spd 3.png Phantom Spd 3 have no effect.
  • Unit selection takes place after all  bonuses on allies are removed, and before any new bonuses or  penalties are applied. All other existing bonuses and penalties count towards their respective stats during unit selection.
  • If multiple units are tied for the highest Atk+Res total, each of those units will receive the effect.
