Dark Sacrifice

An intangible spirit, which looks like a Pseudodragon or Imp (your choice), appears within 5 feet of one creature of your choice that you can see within 30 feet of you. At the end of the current turn, the spirit explodes, and each creature within 5 feet of it must succeed on a Dexterity saving throw or take 1d6 force damage + 1d6 for each other Creature or Familiar under your Control. Until the Spell ends, you can use this effect again, summoning another spirit, on each of your turns as a bonus action.
