Notes
- The Special damage boosting effect of Iceberg can be reduced by damage-reduction effects such as
Archrival, 
A/S Rival Break, and 
Dodge.
- Damage boosting effects stack additively, similar to flat damage-reduction effects and interactions related to the weapon-triangle, such as
Triangle Adept and the weapon-triangle advantage boost. - A foe equipped with Invincibility Seals will neutralize all sources of damage except from Røkkr area-of-effect Specials and the minimum 1 damage from Umbra Burst weapons.
- A foe using attack damage preventing effects can neutralize damage dealt from the foe's own attacks and the unit's attacks (Units with Umbra Burst weapons will take and deal the minimum 1 damage).
