Life Transference

Action • 30ft • V, S • Instantaneous
You sacrifice some of your health to mend
another creature’s injuries. You take 4d8
necrotic damage, which can’t be reduced in any
way, and one creature of your choice that you
can see within range regains a number of hit
points equal to twice the necrotic damage you
take. The damage increases by 1d8 for each
slot level above 3rd.
