Attacking the Shadow without being noticed will give the player an advantage, whilst the enemy gains an advantage if the player is attacked first.[10] Battles use the "Press Turn" system, in which both allies and enemies take turns to attack using weapons, items, or Persona abilities.[5] Using the Tactics option, the player can assign specific battle AI to each party member (in Persona 3 Portable, they may also choose to issue direct commands).[11] Offensive attacks are divided into three physical types; Strike, Slash, and Pierce, and six elements; Fire, Ice, Electricity, Wind, Light, and Dark, attributes of which both Personas and Shadows may possess strengths and weaknesses against.
