If you sacrifice health on the spikes until you have one health left, it spawns three waves of enemies. If you beat all the waves, it shows you the items you are currently carrying, and you pick one from among them. That item will now be bound to the character you're playing, and future runs with that character will start with that item! Each character can only have one bound item at a time. Also, the altar at the bottom of the encampment will display the bound item.
