Thorne's Curse

This spell can only be cast on spellcasters.

When this curse is cast on a character, whenever they cast a spell, the DM can choose to do one of two things: either roll on the Wild Magic table for the character's spellcasting class, or say the spell doesn't work at all. If the DM chooses to roll on the Wild Magic table, the effect lasts for 1d4 minutes. When a character is under this curse, their skin begins to turn black, spreading out from the place they were touched by this curse. The affected area grows one inch in every direction every 3 days. The character under this curse also takes 1 necrotic damage every three days. When a healing spell of any sort is cast on the character, the necrotic damage is not removed. The only way to remove this curse is to touch a phoenix's feather to the center of the affected area.
