Notes[]
- The effect is applied regardless if Mystic Boost's user performs an attack during combat. If foe engages and user cannot counterattack, Mystic Boost's effect will still activate.
- Mystic Boost's user needs to survive the combat for the effect to activate.
- Mystic Boost's healing effect stacks with skills such as
Fury 4, that deal out of combat damage to their owner after combat. - Mystic Boost's after combat healing will not work if the foe has a skill that prevents HP recovery such as Fatal Smoke 3 or Flamelick Breath, or the user has been inflicted with Deep Wounds.
- Attacks that "calculate damage using the lower of foe's Def or Res" include attacks during combat and area-of-effect Specials.
Close Ward, 
Mystic Boost 3, 
Divine Naga, Naga, Splashy Bucket, and Splashy Bucket+ will disable this effect.- Light and Dark and Aureola will disable this effect during combat, but not against area-of-effect Specials.
