Shrines are a newly-added feature to Revita that allow for a small bonus in a combat room. With a small price to pay, they range from being a solid addition to your run to having run-saving potential. All shrines are unlocked from the beginning of the game.

Payment & Corrupted Shrines
For standard shrines, 0.5 HP must be offered to a shrine in order to receive its benefits. With a tinkerer unlock, Corrupted Shrines become available in a run.

These simply serve as an alternate payment method and provide no buffs compared to their counterparts. They have a chance to replace a standard shrine and are paid for with a chance to curse the player instead of 0.5 HP.
