Why does the attack order not change, even if an enemy is inflicted with [Decreased SPD]?

The attack order for characters during battle is determined by each character’s SPD values at the beginning of each turn. As a result, if a character’s SPD value is changed via debuffs or buffs such as [Decreased SPD] or [Increased SPD], it will not affect the attack order during that turn. Instead, the changes will affect the attack order after the beginning of the following turn.

 

In addition, while characters with high SPD values are meant to be more likely to attack sooner during battle, having high SPD does not always ensure that a character will attack before other characters.
