Tainted Keeper is unlocked by reaching Home and using either the Red Key or the Cracked Key to access a special room in one of the walls while playing as Keeper. Tainted Keeper is a character added in The Binding of Isaac: Repentance.


Keepers usually fire 2 short-ranged blood shots in a V formation (similar to Fat Flies) at Isaac when he gets in their line of sight.
