You can cast this 
 Spell only at night. Choose up to three corpses of 
 Humanoids within 
 Range. Each corpse becomes a 
 Ghoul under your control.
Onyx stones rest upon the corpses, grave dirt forming a circle around them. Brackish water drips from your fingers as an eerie glow envelops them. The ghouls rise, lifeless eyes staring ahead.
