Soul Siphon

1-level Necromancy (ritual)

You target any creature in range that has a soul. The target must make a constitution saving throw against your spellsave DC. On a failed save the target takes 1d8 + wis soul damage, on a successful save the target takes half damage.   If the target is willing, the spell automatically succeeds.   If you target yourself and heal another, the heal is doubled.   After the damage is done choose another creature in range, or yourself, to gain hitpoints equal to the damage done. (Does not heal those without a soul).    
 
At higher levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
