Trivia[edit | edit source]
- Most items in this pool will increase stats, increase health, grant pickups, grant trinkets, or some combination of the four. The ones that don't,
Little Steven,
Little C.H.A.D., and
Little Gish, are familiars that will always drop from the boss they are themed after, respectively Steven, C.H.A.D., and Gish. Said bosses are all references to previous games made by Edmund McMillen, and all of them need to be unlocked by beating the chapter they appear in a certain amount of times.
