Moonfire

9-level Evocation

A 120-foot cone of fiery white moonlight flies from your fingertips. All creatures in the area must succeed on a Constitution saving throw, taking 8d12 radiant damage on a failure, and half on a success. An undead creature, or a creature with the shapechanger tag have disadvantage on the saving throw.   A creature that fails the saving throw takes an additional 1d6 radiant damage at the start of each of their turns for the next minute.   Additionally, a creature that fails the saving throw cannot assume a different form for 1 minute, be it with a feature, trait, or spell. Creatures currently in another form are also reverted to their true forms.
