Red Pill

A rare single-use consumable dropped by the Spewer boss. On use, flip a coin: 50% chance to gain Chungus (+4 Constitution), 50% chance to take 8 damage. Chungus is described as strictly beneficial, making it excellent for disorder-synergy builds — and +4 CON is a meaningful permanent stat boost. The 8 damage on failure is painful but not run-ending. For disorder-focused builds that want Chungus, the gamble is absolutely worth taking.

The 50/50 coin flip is unaffected by Luck, making this a pure chance item with no way to bias the outcome through stats. Chungus is a disorder (not just a stat change) which has implications for builds that care about disorder count — notably the Disorder Immunity mutation or Jester-style chaos builds. The 8 damage penalty on failure scales poorly in late game but is genuinely threatening if you're already at low HP when you pop it.

Use it when you're above half HP so the failure case doesn't kill you. On CON-scaling builds, +4 CON is a substantial permanent bonus worth the risk. For disorder builds specifically, Chungus is a highly desirable disorder to acquire, making the Red Pill one of the better consumables from the Spewer fight. Try to save it for a calm moment between fights rather than using it during combat.
