Notes
- The combat reductions and cooldown charge of Deadly Balance will activate if the unit wielding it receives a 【Penalty】.
- The combat reductions and cooldown charge will not be negated if the unit wielding it receives a 【Bonus】.
- If the unit wielding it does not receive a 【Penalty】, or has their 【Penalty】 removed by a source of negative status effect neutralization, the combat reductions and cooldown charge will be negated.
- For more information, see List of keywords.
- The stat decrease that can be applied by Deadly Balance is considered a temporary debuff.
- Only attacks performed by the foe have the Special cooldown charge +X effect. This is true regardless of who initiated combat.
- If the user has a "Special cooldown charge +X" effect and a foe has a "Special cooldown charge -X" effect, the effects will stack.
- For example, if a unit with
Guard Sword+ battles an foe with 
Heavy Blade 3 active:
- The effects will only stack when the foe attacks and the cooldown will go down without penalty or bonus.
- The "Special cooldown charge -X" effect will only take place when the user attacks.
- For example, if a unit with
- If used alongside an effect that also grants "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
Spd/Def Tempo 4 and Spendy Scimitar will neutralize any effects that grant "Special cooldown charge +X" to the foe or inflict "Special cooldown charge -X" on its user.
