Notes
- The stat decrease that can be applied by Atk/Def Ruse is considered a
Penalty.
- Any 【Penalty】 effect on a unit lasts until that unit takes an action. If the unit takes multiple actions in a turn, they will only have Penalties for their first action.
- If the unit also has
Grand Strategy, any Penalties will remain active until the start of that unit's next phase.
- If the unit also has
- Any 【Penalty】 effect on a unit lasts until that unit takes an action. If the unit takes multiple actions in a turn, they will only have
- Atk/Def Ruse applies the
Guard status effect.
- 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
Tempo Echo and 
Arcane Þrima will neutralize effects that inflict "Special cooldown charge -X" on its user. - Atk/Def Ruse does not trigger if the unit receives a
Bonus indirectly from skills, such as from 
Rally Up Atk+. - Cardinal directions refers to spaces directly north, south, east, or west of the user. Distance does not factor.
