Pill effects can vary from one-off effects to permanent changes. Note, however, that if a pill has been used with a certain effect, the same effect may recur with a different pill as well (some examples below). The same goes for additional duplicates that are found. However, if a pill is used and another pill is picked up of identical colors in that playthrough, it will have the same effect as before and its name will be shown, replacing '?'. Note, the pills do not work like Tarot cards which effects can be learned before use, the color of a pill does not foretell its effect in any way. They come in many colors and the effects change every time you play. Pills are random items that are dropped by enemies, found in chests, or spawned in rooms.
