Notes[]
- "If unit initiates combat" means if the user starts combat during the player phase. 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.
- Flow Force will not neutralize the additional follow-up of Potent Follow effects.
- Follow-up effects that are neutralized by Flow Force:
- Effects active on the unit that prevent their follow-up attacks, such as
Windsweep 3, Watersweep 3, or Weaving Fighter. - Effects active on the foe that prevent the unit's follow-up attacks such as Steady Impact, Vengeful Fighter 4, or Foe Cannot Follow-Up.
- Effects active on the unit that prevent their follow-up attacks, such as
- Flow Force can neutralize Penalties during combat.
- Penalties are neutralized by granting temporary buffs of the same amount during combat.
- Temporary buffs from Flow Force do not stack with temporary buffs from effects such as Grand Strategy and Atk/Spd Unity, only temporary buffs from Flow Force will apply.
