The first major boss of Persona Q2 is Kamoshidaman. This fight serves as a tutorial for boss mechanics. Kamoshidaman has no inherent weaknesses, but he is susceptible to various status ailments. His attacks are primarily physical, with some minor Fire and Electric skills. Focus on buffing your party's defense (e.g., Tarunda, Rakukaja) and debuffing Kamoshidaman's attack (e.g., Tarunda).
Kamoshidaman will occasionally summon 'Shadow Kamoshida' minions. These minions are weak to Ice and Wind. Prioritize taking them out quickly to prevent them from overwhelming your party and to gain Boosts. Use your strongest single-target attacks on Kamoshidaman himself. If you have characters with status ailment skills (e.g., Panic, Dizzy), try to inflict them to gain an advantage. Keep your party's HP above 50% at all times, especially your healers. This fight is a test of resource management and basic combat strategy. After defeating Kamoshidaman, you'll complete the first movie and unlock new areas in the Central Cinema.
