Notes

• The stat boost that can be applied during combat by Perspicacious is considered a temporary buff.
• Perspicacious will reduce the effect of non-Special "reduces damage by X%" effects from Specials such as  Vital Astra.
  • Damage-reduction reducing effects stack multiplicatively, unlike interactions related to the weapon-triangle, such as  Triangle Adept and the weapon-triangle advantage boost.
    • For example, if a unit has  Halves non-Special damage reduction and a foe with  Dodge is on a space with  【Divine Vein (Water)】, the maximum total damage-reduction is reduced to 10%, since the two effects reduce the damage to (1 − ((40% − 50%) − 50%)) = 90% of the original damage instead of 60% of the original damage.
  • Each damage-reduction effect is reduced individually.
    • For example, if a unit has  Halves non-Special damage reduction and the foe has both  Spurn 4 and  Dodge, the maximum total damage-reduction is reduced to 40%, since the two effects reduce the damage to (1 − (50% − 50%)) × (1 − (40% − 50%)) = 60% of the original damage instead of 30% of the original damage.
  • Perspicacious will not reduce the effect of Special "reduces damage by X%" effects or flat damage-reduction effects such as  Archrival or  Pair Up 4.
  • For more information, see Damage calculation.
• The temporary buffs and reduce non-Special "reduce damage by X%" effects of Perspicacious will not apply to the user's allies if the user is inflicted with  Time's Grip, the user's allies are inflicted with  Feud, or the user's allies are in combat against a foe with skills such as  Impenetrable Void and  C Feud 3.
• The stat reduction that can be applied during combat by Perspicacious 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.
  • If the effect is active, the unit will gain 2 charges from both attacking and being attacked.
• If used alongside another source of "Special cooldown charge +X", only the higher of the two charge increases 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 grant "Special cooldown charge +X" to the foe.
• If unit attacked means if the user attacked at any time during combat. They do not need to initiate combat, deal damage, or survive.
  • This means that if the foe initiates combat and the user cannot counterattack, the effect will not trigger.
• The stat decrease that can be applied by Perspicacious 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.
