Bloodbridge

You touch two creatures and draw blood
out from one (the “donor”), channel it
through yourself, and infuse it into the other
(the “recipient”). This causes the donor to
lose hit points equal to 1d6 + your
spellcasting ability modifier and the recipient
to gain 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.
