I Found Pills


  • Bad Trip and Health Down pills will turn into I Found Pills when Isaac is at one heart.
  • Neutral pills will not have a secondary effect.
  • If any stat down pills were taken before picking up the item, a damage increase is given for each pill.
  • Pills are only converted while held by a character with False PHD. For example: If playing as Jacob and Esau Jacob and Esau and Jacob Jacob has this item, pills that got converted into 'bad' pills like a Tears Down pill can be given to Esau Esau to convert them back into a Tears Up pill, or whatever the pill was originally.
  • Losing the item by either dropping it as Tainted Isaac Tainted Isaac or re-rolling it via D4 D4, etc., causes the damage buffs given to be removed.


  • A Pony A Pony/White Pony White Pony: Effectively converts all Speed Down pills into Damage Up as long as one of the ponies are being held, since they will always give a minimum of 1.5 speed.
  • Black Feather Black Feather: Counts as an 'evil item, granting a damage up.
  • Lucky Foot Lucky Foot / PHD PHD / Virgo Virgo: Pills can now be both good and bad again. The other effects of False PHD still apply.
  • The Wafer The Wafer: Using a Bad Trip pill will only deal half a heart of damage and spawn a full Black Heart, resulting in a net gain of health.
    • The Wafer + Placebo Placebo: Allows for farming infinite health using Bad Trip pills.


  • Libra Libra: The balancing of stats mostly leads to a net decrease between Stat Downs and +0.6 damage up, while Luck Down provides the balanced +0.6 damage and luck -1.0.


  • Telepills will be converted to ??? even if the latter has not yet been unlocked.
  • Gulp! and Vurp! will be converted to Horf! even if the latter has not yet been unlocked.
