Dire Judgement

1/day

Each creature of the onyx magistrate's choice that is within 30 feet of the magistrate and aware of it must succeed on a DC 16 Wisdom saving throw or be cursed with dire judgment. While cursed in this way, the creature can't regain hp by magical means, though it can still regain hp from resting and other nonmagical means. In addition, when a cursed creature makes an attack roll or a saving throw, it must roll a d4 and subtract the number from the attack roll or saving throw. The curse lasts until it is lifted by a remove curse spell or similar magic.
