Robotic Arm

Defeat C-800 on Hard difficulty to unlock the Robotic Arm item. On Hard, C-800's 50 Brace stacks become even more problematic with increased HP and elite modifiers layered on top. His grenade openings deal more damage, and his random weapon switches between Shotgun, Sniper Rifle, and Machine Gun are deadlier. Bloodletting remains the best counter for stripping all Brace in a single turn. Stack Brace on your own cats to survive the firearm barrage, use Holy Shield against sniper shots, and avoid casting spells recklessly since C-800 punishes spellcasters with a lethal melee combo. Thorns and Reflect help chip away at his Brace passively.
