Antimagic Cone. This monster’s central eye creates an area if antimagic, as in the antimagic field spell, in a 150-foot cone. At the start of each of its turns, this monster decides which way the cone faces.
ACTIONS
Multiattack. The creature uses its Frightful Presence. It hen makes three attacks: two with its claws, and one with its bite.
Claws. Melee Weapon Attack: +15 to hit, reach 15ft., one target. Hit: 24 (4d6+10) slashing damage.
Bite. Melee Weapon Attack: +15 to hit, reach 15ft., one target. Hit: 32 (4d10+10) piercing damage. On a critical hit against a target in an astral body (as with the astral projection spell), this monster can cut the silvery cord that tethers the target to its material body, instead of dealing damage.
Frightful Presence. Each creature of this monster’s choice that is within 120 feet of it and aware of it must succeed on a DC 18 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to this monster’s Frightful Presence for the next 24 hours.
