Notes
- The stat increase that can be applied by Spd Opening is considered a
Bonus.
- Unit selection takes place after all Bonuses on allies are removed, and before any new Bonuses or
Penalties are applied. All other existing Bonuses and Penalties count towards their respective stats during unit selection.
- Spd Opening does not compare Spd stats, so 【Phantom】 effects will not work.
- If multiple units are tied for the highest Spd, each of those units will receive the effect.
