Notes

• The stat increase that can be applied by Odd Def Wave is considered a  Bonus.
  • Any 【Bonus】 on a unit, including  Bonuses, 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.
• Odd Def Wave 4 will neutralize the "Special cooldown charge +X" effect on foes from effects such as  Heavy Blade 4,  Special Cooldown Charge +1, or the Grand Conquests  Infantry area effect.
  • Since the "Special cooldown charge +X" effect will be neutralized on foes, Odd Def Wave 4 will also stack with the "Special cooldown charge -X" effect inflicted on the foe from effects such as  Guard Sword+,  Guard, or 【Divine Vein (Green)】, unless the foe is equipped with skills that neutralize the "Special cooldown charge -X" effect on unit.
• Odd Def Wave 4 will neutralize the "Special cooldown charge -X" effect on unit from effects such as  Guard Sword+,  Guard, or 【Divine Vein (Green)】.
  • Since the "Special cooldown charge -X" effect will be neutralized on unit, Odd Def Wave 4 will also stack with the "Special cooldown charge +X" effect on unit from effects such as  Heavy Blade 4,  Special Cooldown Charge +1, or the Grand Conquests  Infantry area effect, unless the foe is equipped with skills that neutralize the "Special cooldown charge +X" effect on unit.
• The stat increase that can be applied by Odd Def Wave 4 is considered a temporary buff.
