Shaman Healer's Necklace

Adventuring Gear Varies (this item requires attunement)

When making a medicine check to stabilize a creature, you can use your constitution modifier instead of your wisdom modifier. If you do so, you can transfer hitpoints from yourself to the creature equal to your constitution modifier, a minimum of one. You can do this for free once per day. Every use thereafter gives the healer one level of exhaustion.
