  • During combat, the damage boosting effect of  Treachery is calculated after calculations of effects that trigger "during combat".
  • The damage boosting effect will also affect area-of-effect Specials such as  Rising Flame and  Growing Thunder.
  • The damage boosting effect will not negated nor reduced if the unit receives  Penalties.
  • The damage boosting effect will be negated only during combat if the unit is affected by  Ploy.
  • The damage boosting effect will be negated if the unit is affected by  Panic (and not affected by  Null Panic), or the unit has their  Bonuses removed by a source of positive status effect neutralization.
  • A foe equipped with  Embla's Ward,  Múspellflame,  Niðavellir Axiom, File:Nine-Realm Pact.png Nine-Realm Pact, or  Gold Perfection will neutralize all sources of damage during combat except the minimum 1 damage from Umbra Burst weapons.
