Bind Life

You touch a willing creature, binding your lifeforce to the lifeforce of the touched creature. Anytime the creature takes damage you are able to sense the amount of damage taken and vice versa. If you are reduced to 0 hit points and the creature you are bound to has more than 0 hit points you regain 1 hit point at the start of your next turn and vice versa. You may only be bound to one other creature at a time and vice-versa. If you bind yourself to a new creature, your bond with the original creature is lost, if the creature you are bound to binds itself to another creature, its bond to you is lost. You can end the spell as a bonus action.
