The Binding of Isaac: Repentance/Additions

Gold Pills
Gold Pills (or Golden Pills) can be used multiple times and grant a random pill effect, even from pills not in the pill pool. Every time a Golden Pill is used it has a chance of being consumed. Its Horse Pill variant will make it give only Horse Pill Effects.

Horse Pills
Horse Pills appear as larger versions of the standard pills with a more powerful effect, and their effects and appearances are similarly randomly chosen. All items that work with pills work identically with horse pills. A horse pill with a given effect has the same color as the normal pill does. Unlocked by:
