Notes[]
- Grants the effect of
Flashing Blade 3 to Infantry allies within 2 spaces.
- Only attacks performed by the user have the "Special cooldown charge +X" effect. This is true regardless of who initiated combat.
- 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 Accelerate Special, the effects will stack and the cooldown will go down without penalty or bonus.
- The effects will only stack when the user attacks and the cooldown will go down without penalty or bonus.
- The "Special cooldown charge -X" effect will only take place when the foe attacks.
- 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 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 3 and Spendy Scimitar will neutralize effects that grant "Special cooldown charge +X" to the foe.
- The Special cooldown charge effect of Infantry Flash will not apply to the user's allies who are in combat against a foe with skills such as Impenetrable Dark and C Feud 3.
