Curse of Wild Magic

When this spell is cast on a creature, they must make a DC 20 wisdom saving throw. On a success, nothing happens. On a failure, that creature must immediately roll on the Wild Magic Surge table. For 1 hour, the affected creature must roll on the Wild Magic Surge table every time they cast a spell. When the spell wears off, the affected creature must succeed on a DC15 wisdom saving throw or roll on the Wild Magic Surge table one last time.
