Multiattack

The dream eater uses its Lotus Scent. It then makes one Bite attack and one Claw attack.

Bite

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 15 (2d10 + 4) piercing damage.

Claw

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) slashing damage, and the target is grappled (escape DC 14) if it is a Large or smaller creature. Until this grapple ends, the creature is restrained. The dream eater has two claws, each of which can grapple only one target.

Lotus Scent

The dream eater secretes an oily chemical that most creatures find intoxicating. Each creature that isn't a Construct or Undead within 15 feet of the dream eater must succeed on a DC 14 Constitution saving throw or be poisoned for 1 minute. While poisoned, the creature is charmed by the fiend. A poisoned 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 the dream eater's Lotus Scent for the next 24 hours.

Waking Dreams (Recharge 5-6)

Each creature within 20 feet of the dream eater must make a DC 14 Charisma saving throw. On a failure, a creature takes 21 (6d6) psychic damage and is incapacitated for 1 minute. When it moves, an incapacitated creature moves in a random direction. On a success, a creature takes half the damage and isn't incapacitated. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
