In Persona 5 Tactica, the gameplay has been updated and changed from previous installations, and one of these changes was in the skill trees. As in many games, choosing the right skills for different characters is important as it determines how you play the game. Persona 5 Tactica utilizes turn-based battle gameplay, meaning each move matters and skills that affect those must be chosen carefully.
