Aura of Erebos. Any creature that starts its turn within 10 feet of the giant must succeed on a DC 18 Constitution saving throw, or it takes 10 (3d6) necrotic damage and can't regain hit points until the start of its next turn. On a successful saving throw, the creature is immune to the giant's Aura of Erebos for 24 hours.
Magic Resistance. The giant has advantage on saving throws against spells and other magical effects.
Multiattack. The giant makes two slam attacks.
Slam. Melee Weapon Attack: +11 to hit, reach 15 ft., one target. Hit: 20 (3d8 + 7) bludgeoning damage plus 10 (3d6) necrotic damage.
Noxious Gust (Recharge 5–6). The giant exhales a mighty gust that creates a blast of deadly mist in a 60-foot line that is 10 feet wide. Each creature in that line must make a DC 18 Constitution saving throw. On a failed save, the creature takes 36 (8d8) necrotic damage and is knocked prone. On a successful save, a creature takes half as much damage and isn't knocked prone.
