Description Accelerates Special trigger (cooldown count-1). At the start of turns 1 through 3 or if unit's HP < 100% at start of turn, grants Special cooldown count-1 to unit. During turns 1-3, or if unit's HP < 100% at start of combat, grants Atk/Spd+6 to unit during combat, and also, if Special triggers (excluding area-of-effect Specials), deals +7 damage and neutralizes "reduces damage by X%" effects from non-Special skills.


  • Thunderer Tome's cooldown count changing effect will not trigger if the unit is inflicted with  False Start.
  • Cooldown count changes from skills that activate at the same time as Thunderer Tome (at start of turn) are not considered in Thunderer Tome's conditions.[1] Skills such as Infantry Pulse 3.png Infantry Pulse 3, Icon Class Green Tome.png Tome of Reglay, and Odd Pulse Tie 3.png Odd Pulse Tie 3 will have their effects stack.
  • The stat increase that can be applied by Thunderer Tome is considered a combat boost.
  • Deals +7 damage when an offensive Special triggers.
    • The added damage from activating a Special is a fixed +7 and ignores Def and Res, but can be reduced by damage reduction skills such as Skilliconspecial.png Pavise.
    • For more information, see Damage calculation.
  • The damage-reduction neutralzation effect of Thunderer Tome will not apply to the damage-reduction effects of Flow Flight 3.png Flow Flight 3, Icon Class Green Axe.png Pastel Poleaxe, and defensive Specials.
    • The damage-reduction neutralzation effect will apply to damage-reducing Specials such as Skilliconspecial.png Vital Astra.
