Dharnon's Soul Spikes

You pull soul and blood essence from a target, coalescing them into three spikes that circle around your body. Choose one creature within range. That target must make a Constitution saving throw. A creature takes 3d6 necrotic damage on a failed save, or half as much damage on a successful one. When you cast the spell — and as a bonus action on each of your turns thereafter — you can throw one of the spikes at any creature within range. You can choose to either make a spell attack roll and deal 3d6 necrotic damage, or choose the target and heal them for 3d6 hit points.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you create one more spike and deal an extra 2d6 initial necrotic damage for each slot level above 3rd.
