Engulf. The Dream Harvester can move up to its speed and enter the space of a Large or smaller creature. That creature must make a DC 26 Strength saving throw or be engulfed and restrained by the Dream Harvester. While engulfed, the creature takes 44 (8d10) bludgeoning damage plus 22 (4d10) psychic damage at the start of each of the Dream Harvester's turns. The Dream Harvester can have up to three creatures engulfed at a time.

The creature must make a DC 26 Wisdom saving throw or fall asleep for 1 minute. While asleep, the creature is vulnerable to psychic damage and any damage taken from psychic attacks is doubled. The creature wakes up if it takes damage or if another creature takes an action to wake it up.
