The Ultimate Gauge increases when a character takes action or receives damage. Gains from taking damage are small, while acting provides a larger increase, typically 60 to 90. A character can usually use their Ultimate after acting 4 or 5 times.

Ultimates can be used regardless of the turn order, allowing you to unleash them before an enemy attacks.
