Persona fusion is the most powerful tool at your disposal. Beyond basic fusion, understand 'Fusion Spells' (unique skills gained by fusing specific Personas together, like Cadenza from Orpheus and Apsaras) and 'Skill Cards' (obtained from maxed Social Links or Shuffle Time, allowing you to teach skills to any Persona). Always aim to inherit useful skills from parent Personas. Pay attention to elemental resistances and weaknesses when fusing; a Persona with no weaknesses is invaluable. The 'Triangle Spread' fusion allows for more complex combinations. Don't be afraid to experiment, and always save before a major fusion session. Maxing out Social Links is crucial for unlocking the most powerful ultimate Personas for each Arcana.
