Description Grants Spd+3. If unit initiates combat, grants Atk/Spd+5 during combat. If unit initiates combat and is within 2 spaces of support partner, foe cannot counterattack and unit and support partner swap spaces after combat. (If unit is within 2 spaces of more than one support partner, swap does not occur.)
Effect:【Dagger 7】

【Dagger 7】
After combat, if unit attacked, inflicts Def/Res-7 on target and foes within 2 spaces of target through their next actions.


  • If unit initiates combat means if the user starts combat on their turn. The unit does not need to deal damage, nor be the first to attack.
    • However, if the effect is applied after combat, the unit must also survive it to fulfill this condition.
  • The stat increase that can be applied by Constant Dagger is considered a combat boost.
  • Constant Dagger can prevent the foe from counterattacking.
    • A foe with Null C Disrupt 3.png Null C-Disrupt 3 will be able to counterattack.
    • A foe with Icon Class Green Axe.png Nifl's Bite will only able to counterattack against ranged units.
  • Movement occurs only if both the unit and the target can enter the target spaces normally.
  • Constant Dagger triggers before Røkkr area-of-effect Specials.
  • The counterattack prevention and support partner swapping effects of Constant Dagger will only activate if the unit has a support partner active on the map.
  • If unit attacked means if the wielder 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 activate.
  • The stat decrease that can be applied by Constant Dagger is considered a  penalty.
    • Any 【Penalty】 on a unit, including  penalties, lasts until that unit takes an action. If the unit takes multiple actions in a turn, they will only have the penalty 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.
