Unveiling weaknesses is crucial in Persona 3 Reload as it can lead to powerful All-Out Attacks. However, some gatekeeper bosses like the Arcanist Decapitator pose challenges with resistances and no clear weaknesses, testing your strategic prowess. Here's how you can triumph over this formidable foe.

Locating the Arcanist Decapitator

Yabbashah Block (First Half)

The Arcanist Decapitator awaits on the 82nd floor of the Yabbashah Block within Tartarus. Positioned as the second gatekeeper boss in this segment, it follows the Ochlocratic Sands gatekeeper. Utilize the floor's teleporter to regroup and prepare your team effectively for the impending battle.

Defeating the Arcanist Decapitator

Arcanist Decapitator's Vulnerabilities

The Arcanist Decapitator boasts no inherent weaknesses and resists Ice and Wind attacks. To emerge victorious, focus on employing physical assaults and aim for critical hits. Accompanied by the Heat Overseer and the Sky Overseer, ensure your team can strike their weaknesses effectively.

Building a balanced team that can exploit all Affinity weaknesses is vital. Consider including Yukari, Mitsuru, and Akihiko in your lineup. Equip the protagonist with Personas specializing in buff/debuff abilities or excelling in Physical Skills. Coordination is key; target enemies strategically to avoid inadvertently aiding them.

Utilize tactical maneuvers like the Shift feature to exploit vulnerabilities efficiently. Prioritize eliminating the Sky Overseer and Heat Overseer before engaging the Arcanist Decapitator directly. Mitigate Fire-based attacks by equipping Mitsuru and the protagonist with appropriate accessories.

Employ skills such as Tarukaja for Attack boosts, Sukukaja for enhanced Accuracy/Evasion, and Rakunda to weaken targets' defenses. Leverage the Revolution Skill for increased critical hit rates. By focusing on strategic skill deployment and coordinated attacks, you can emerge victorious against the Arcanist Decapitator and its allies.
