Brain Wash. When the Zoneless Doll casts an enchantment or spell to charm one or more creatures, it can alter one creature's understanding so that it remains unaware of being charmed. Additionally, if the Zoneless Doll wants to, these creatures forget what they did while charmed.

Etherealness. The Zoneless Doll is freely able to travel between the Ethereal Plane and Material Plane at will.

False Appearance. While the Zoneless Doll remains motionless, it is indistinguishable from an ordinary object.

Telepathic Bond. The fiend ignores the range restriction on its telepathy when communicating with a creature it has charmed. The two don't even need to be on the same plane of existence.

True Form. All means of detection show this state to be it's true form.

Innate Spellcasting. The Zoneless Dolls innate spellcasting ability is Charisma (spell save DC18+15 to hit with spell attacks). The Zoneless Dolls can innately cast the following spells, requiring no material components.

At-will: Charm Person (cast as an 18th-level spellcaster) WIS Save (DC18)

At-will: Mind Sliver (cast as an 18th-level spellcaster.) INT Save (DC18) (4d6)

True Form. All means of detection show this state to be it's true form.

Bite. Melee Weapon Attack: +15 to hit, reach 5 ft., one target. Hit:  (6d8+8) piercing damage.

Charm. One humanoid the fiend can see within 30 feet of it must succeed on a (DC18) Wisdom saving throw or be magically charmed for 1 hour. The charmed target obeys the fiend's telepathic commands. If the target suffers any harm or receives a suicidal command, it can repeat the saving throw, ending the effect on a success. If the target successfully saves against the effect, or if the effect on it ends, the target is immune to this fiend's Charm for the next 24 hours. The fiend can have only one target charmed at a time. If it charms another, the effect on the previous target ends.

Grease. Slick grease covers the ground in a 10-foot square centered on a point within range and turns it into difficult terrain for the duration. When the grease appears, each creature standing in its area must succeed on a Dexterity saving throw or fall prone. A creature that enters the area or ends its turn there must also succeed on a Dexterity saving throw or fall prone.

 Puppet Control: The Zoneless Doll casts Dominate Person on a target of its choice within 60ft. Target must succeed on a (DC18) Wisdom saving throw or be charmed by the fiend for the duration, target rolls with advantage if fiend has attacked target. If the fiends succeeds in charming the target, they cast Plane Shift upon themselves. During targets initiative they control the target to take an action in combat, Attack, Cast a Spell, Dash, Disengage, Dodge or Grapple, status effects apply (rage, extra attack, traits, etc.) While under control target, magical or not, can cast At-will Spells of the Zoneless Doll as a bonus action. At Zoneless Doll's initiative, they control the target to take an action in combat, casting an At-will Spell as a bonus action. During this time fiend can also cause the target to use a reaction, this causes the fiend to use its reaction for the round of combat and may not use another. Each time the target takes damage, it makes a new Wisdom saving throw against the spell. If the saving throw succeeds, the spell ends. When the spell ends, the Zoneless Doll Plane shifts back to a zone within 25 ft. of where it teleported from.
