Notes
- The stat decrease that can be applied by Reopening is considered a temporary debuff.
- The "Special cooldown charge -X" effect will stack with the "Special cooldown charge +X" effect.
- For example, if a unit is affected by both Guard and
Special Cooldown Charge +1, the effects will stack and the cooldown will go down without penalty or bonus.
- For example, if a unit is affected by both
- If used alongside another source of "Special cooldown charge -X", only the higher of the two charge reductions will apply.
- This means that if a unit has two "Special cooldown charge -1" effects from two different sources, the battle will play out as if only one "Special cooldown charge -1" effect is active.
- Skills such as
Spd/Def Tempo 4 and 
Whirling Grace will neutralize effects that inflict "Special cooldown charge -X" on its user.

Gust, 
Atk/Spd Excel, and 
Dodge.
- A foe equipped with
Embla's Ward, 
Múspellflame,

Dominance.

Everliving Domain can trigger, the damage-reduction effect will not trigger and the user will still survive with only 1 HP. - "Reduces damage by X%" effects stack multiplicatively, unlike interactions related to the weapon-triangle, such as
Triangle Adept and the weapon-triangle advantage boost.
- Special "reduces damage by X%" effects cannot be neutralized or reduced by effects such as
Share Spoils or 
Halves non-Special damage reduction. - For more information, see Damage calculation.
