Brain Chip

Brain Chip is an uncommon head armor that boosts every stat by +1 across the board, but the Uncontrollable passive means the cat acts on its own without player direction. The all-stat upgrade is excellent value, but losing direct control is a real cost — the cat will follow its AI instincts rather than your strategy. Best on cats with simple, aggressive kits that play well on autopilot.

The all-stats +1 applies to STR, DEX, INT, CHA, CON, SPD, and LCK simultaneously, making it the most broadly beneficial stat item at uncommon rarity. Uncontrollable removes player input for that cat entirely — it takes actions based on AI logic, targeting whatever seems most threatening. Simple, aggressive cats with straightforward kits (basic melee attackers, thorns tanks, or spawn-heavy builds) function well on AI since their optimal play is obvious.

Brain Chip works best as a set-and-forget helmet on expendable frontliners or pure physical tanks that don't require strategic ability timing. Avoid on cats whose value depends on precise targeting, ability combos, or specific positioning decisions — the AI will not execute those correctly. Think of it as upgrading a unit to a smarter companion rather than a player-controlled fighter.
