Animate Ghoul

This is a blood magic spell.

You raise one Medium humanoid corpse as a ghoul under your control. Any class levels or abilities the creature had in life are gone, replaced by the standard ghoul stat block.

At Higher Levels. When you cast this spell using a spell slot of 3rd level, it can be used on the corpse of a Large humanoid to create a large ghoul. When you cast this spell using a spell slot of 4th level, this spell creates a ghast, but the material component changes to an onyx gemstone worth at least 200 gp.
