Blood Bridge

You touch two creatures and draw blood out from one (the “donor”), channel it through yourself, and infuse it into the other (the “recipient”) within 15ft (the target can be yourself at full healing minus 1). This causes the donor to lose hit points equal to 1d8 + your spellcasting ability modifier and the recipient to gain half that number of hit points. The donor does not need to be willing and may make a Dexterity saving throw to evade your grasp.

This spell has no effect on undead, constructs, plants, and other creatures that lack blood.

At Higher Levels: If cast using a 2nd level spell slot or higher, the damage and healing increases by 1d8, up to a maximum of 6d8
