Touch of Unlife

You touch an undead creature and concentrate raw unholy energies into them, bolstering their life force. The target regains 2d6 hit points.

If the target is not an undead, it instead must make a Constitution saving throw, taking 2d6 necrotic damage on a failed save, or half as much on a success.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the amount healed/damage dealt increases by 1d6 for every level above 1st.
