Partial Incorporealness. The Visage is not technically incorporeal, it cannot pass through solid objects, but it can move through very small openings, like keyholes.

Lucidity Control. The Visage can control the perceptions of others. As a bonus action, the visage can control the perceptions of up to six targets. It can change an entire terrain, make objects seem further or closer away, create subtle changes on building design or architecture, change what the target hears, smells, sees, feels, and more. It can even completely cut off all the target’s senses. There is no save if the target does not suspect the illusions. If the target believes their senses are being manipulated, they can make a Wisdom Save DC 15 to see past the illusions for one round. This effect lasts as long as the Visage maintains concentration.

Natural Spellcasting. The Visage uses Charisma as its casting ability (DC 14, +6), and can cast the following spells:

1/Day: Dominate Monster

Assume Identity. The Visage can assume the identity of a victim it kills by stealing a portion of their spirit before it goes to the afterlife. This disguise is nearly perfect, and only close friends have a chance to tell that something is wrong (Insight DC 14 for close friends, family). If it changes form back to normal or assumes another form, it must release the spirit (assuming the spirit was not consumed; see below). It cannot use its claws, but it can use its Lucidity Control and Natural Spellcasting.

While the Visage is using this ability, the victim cannot be raised, resurrected, or affected by any spell which targets the dead (such as speak with dead). If the Visage is killed or releases the spirit within one week, the spirit can go to its proper afterlife and can be affected by spells as normal. If not, the Visage consumes the spirit entirely. It is gone forever - never to experience it's appropriate afterlife.

Multiattack. Visage can attack with two claws.

Claw. Melee Weapon Attack:  +7, reach 5 ft. One target, hit 7 (1d8+3) slashing damage. Hit: 7 (1d8+3)
