Bakual

Detect Life. The Bakual can sense the presence of any living creatures with 100 feet. It learns the types of creatures, the number of creatures, and their locations, but does not learn who the creatures are.

Incorporeal Movement. The Bakual can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.

Sleepless Dreams. The Bakual gains no benefit from taking a short or long rest, as it cannot sleep.

Psychic Defense. The Bakual adds it's Wisdom modifier to it's Armor Class.

Slam. Melee Weapon Attack: +4 to hit, reach 5 ft., 1 target. Hit: 5 (1d6+1) bludgeoning damage. 

Induced Trance. Ranged Spell Attack: +5 to hit, range 30 ft., 1 target. Hit:  7 (1d10 + 2) psychic damage. If the target isn't resistant to psychic damage, it has disadvantage on it's next attack roll.

Dream Eater (Recharge 5-6). One unconscious creature that the Bakual can see within 5 feet must make a DC 13 Charisma saving throw or have their dreams eaten. A creature that fails the saving throw does not benefit from a long or short rest, and remains asleep. A creature that succeeds the saving throw does benefit from their rest, and wakes up upon succeeding.

If the affected creature failed their saving throw, the Bakual immediately gains all the benefits of a long rest. If the affected creature succeeded their saving throw, the Bakual immediately gains the benefits of a short rest, and can spend any hit dice they have.

Each time the Bakual uses it's Dream Eater ability, and the affected creature fails it's saving throw, the Bakual gains a bonus to it's maximum HP equal to the creature's level, or half it's CR (minimum of 1). The Bakual cannot target the same creature with this ability within 24 hours, nor can it target the same creature twice in a row.
