Binding of Isaac: Rebirth Wiki

(in Repentance)

Dummy is a special enemy available through the Debug Console's spawn command.

It is immobile, harmless, and visually identical to a normal Shopkeeper but has a damage counter overlaid on the face, adding up any and all damage taken. Touching the Dummy will reset the counter to 0.00.

Although the Dummy has the limited amount of 10000 HP, it is nearly impossible to kill as its health refills completely on every internal tick of the game; it must take 10000 damage in one frame to be destroyed.

The game considers the Dummy to be a boss, giving it resistance to status effects, immunity to instant kills from Collectible Euthanasia iconEuthanasia and Collectible Little Horn iconLittle Horn and practical immunity to Collectible Eraser iconEraser. However, this does allow the Dummy to be killed using a Chaos CardChaos Card.
