Notes[ | ]

  • The stat increase that can be applied by Firestorm Boost is considered a temporary buff.
  • The "Special cooldown charge -X" effect will stack with the "Special cooldown charge +X" effect.
    • For example, if a unit is affected by both Status Effect Guard Guard and Status Effect Special Cooldown Charge 1 Special Cooldown Charge +1, the effects will stack and the cooldown will go down without penalty or bonus.
  • 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 Spd/Def Tempo 4 and Icon Class Green Axe Whirling Grace will neutralize effects that inflict "Special cooldown charge -X" on its user.
