This card's ability can be activated as many times as you like as long as you have a room to sacrifice. However, it's ability only applies to 1 Hero, excess or remainder damage does NOT carry over to another Hero.


A card that works well in conjunction with Recycling Center. It also works well when a player has rooms that are built over rooms with an uncover effect, as the uncover effect will activate when using this card.

This room is also handy later on in the game, as the player will have most likely built up room stacks which can easily be destroyed to kill Epic Heroes.


The idol and boulder in the artwork may be a reference to the opening sequence of the film "Indiana Jones and the Raiders of the Lost Ark"
