    • Retro Vision
  • 4 Rooms:
    • Gulp!
    • I can see forever!
    • Stat-downs (health, range, speed, tears, luck, shot speed)
  • 6 Rooms:
    • Hematemesis
    • Experimental Pill
    • Vurp!
  • 12 Rooms:
    • 48 Hour Energy
    • Balls of Steel
    • Full Health
    • One makes you larger/small
    • Pretty Fly
    • Stat-ups (health, range, speed, tears, luck, shot speed)

Golden Pills use the recharge time of the pill they mimicked. Recharge time is unaffected by whether or not it was a normal pill or Horse Pill.

Note that because the recharge time is determined after using the pill, Placebo cannot be used as a way to narrow down what type of pill Isaac is holding before he uses it.

Synergies[]

  • Removed in Repentance 48 Hour Energy: Can spawn an unlimited number of Lil' Batteries, allowing unlimited use of another activated item or pill.
  • Removed in Repentance Balls of Steel + Sharp Plug Sharp Plug: The player can gain functional invincibility.
    • Removed in Repentance The Wafer The Wafer: Allows for Virtually infinite health.
  • Added in RepentanceButter! Butter!: Because Placebo is dropped upon usage, the recharge time is reset to 4, allowing to use more expensive pills much more frequently.
  • Added in Repentance Vurp: Allows pills that normally take 12 rooms for Placebo to charge to be used twice as frequently.

Interactions[]

  • Added in RepentanceBook of Virtues Book of Virtues: Spawns white wisps on the middle ring. The wisps spawn Pills when destroyed. The effects of the wisps and types of pills they spawn is independent from Placebo's charge time and the most recently used pill. Unlike Blank Card Blank Card and Added in RepentanceClear Rune Clear Rune, enemies killed by these wisps' tears do not have a chance to drop pills.
  • Starter Deck Starter Deck: All pills are replaced by cards, rendering Placebo useless.
  • If used with Bethany Bethany or Tainted Bethany Tainted Bethany, using a pill that has a larger charge requirement than Placebo's current will still consume soul or blood charges equal to the difference (likely a bug).

In-game Footage[]

Trivia[]

  • Placebo is a medicine or procedure prescribed for the psychological benefit to the patient rather than for any physiological effect.

Bugs[]

Bug Bug! Strange behavior when the player has a 12-charge pill, Placebo is dropped on the ground with more than 4 charges and the player has Battery - when the player re-equips Placebo, it's capped at 8 charges, which stack strangely in the UI
