Persona 3 Reload goes a long way toward improving the gameplay mechanics from the original release, and the introduction of the Theurgy mechanic is one of the biggest combat additions. Theurgy skills allow Persona 3 Reload players to unleash powerful moves after fully filling a party member's Theurgy Gauge, and each character has their own unique Theurgy skills available to them. However, some Theurgy skills are much stronger than others, and players will definitely want to prioritize the use of certain skills over others.
