Dread Curse of Azathoth

Recorded only in desecrated tombs by worshipers of Azathoth, this spell withers a creature that you can see within range. This spell reduces each of the target’s ability scores to 3 (unless they were already lower). The target can follow simple instruction and recognizes friends. It can’t cast spells. Although the target gets no saving throw to resist the spell initially, the target makes a Charisma saving throw (using its new Charisma ability modifier) at the end of each of its turns. On a success, the spell ends. This spell can be ended early by greater restoration, heal, or wish.
