Blood Bridge

You place a hand on two creatures within range. The first creature takes 1d6 necrotic damage, and the second creature gains temporary hit points equal to the necrotic damage dealt. The first creature can make a Dexterity saving throw to avoid the grasp and prevent the damage. This spell cannot reduce the first creature's hit points below 1.

This spell has no effect on constructs or undead.

The amount of damage/temporary hit points dealt by this spell increases by 1d4 for each slot level above 1st.
