8th-level transmutation (sorcerer, wizard)
Casting Time: 1 action
Range: 60 feet
Components: V, S, M (a lump of melted wax infused with blood)
Duration: Concentration, up to 1 minute (or permanent; see text)
This spell functions as mutation but affects multiple creatures, no two of which are more than 30 feet apart.
Targets need not be of the same type or subtype, nor must they all acquire the same deformities (if using the temporary fleshcurdle-like effect) or mutations (if choosing to cause permanent mutation). However, if all targets are of the same type (and subtype, if applicable) and you choose to make all of the deformities or mutations inflicted by the spell the same for all targets, all targets have disadvantage on their saving throw.
