Gravity Well. The demon exudes a powerful gravity field in a 30-foot radius around itself. This area is considered difficult terrain for all non-evil creatures. Other creatures within this field cannot jump or fly and have disadvantage on Strength and Dexterity checks. Additionally, all ranged weapon attacks against the demon are made with disadvantage.
Actions
Multiattack. The demon makes three attacks: two with is claws and one with its tail.
Claw. Melee Weapon Attack: +8 to hit, reach 5ft., one target. Hit: 8 (1d8 + 4) slashing damage plus 9 (2d8) force damage.
Tail. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 15 (2d10 + 4) slashing damage plus 9 (2d8) force damage.
Crushing Forces (Recharge 6). The demon causes the power of the gravitational field to increase tenfold for a moment. Each creature in the area of the gravity well must make a DC 15 Strength saving throw, taking 44 (8d10) bludgeoning damage and being knocked prone on a failed save, or half as much damage and not knocked prone on a successful one.
Gravity Surge (3/Day). The demon causes the gravitational forces around it to surge with power. Each creature in the area of the gravity well must succeed on a DC 15 Strength saving throw or be pulled to an unoccupied space adjacent to the demon. Afterwards, the demon makes a claw attack against each enemy pulled, making a separate attack roll for each attack.
