Void Manifestation

Medium aberration, chaotic evil

Void Manifestations are fragments of Void energy given temporary form by the Colossus's psychic emanation. They appear in the sub-foundations as the party descends: humanoid shapes of darkness, cold, and grief. They are not intelligent. They are emotional echoes weaponised by the Void. They attack anything warm, anything alive, anything that reminds the Void of what it is not.

Traits

Incorporeal Movement. The Manifestation 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.

Grief Aura. Creatures within 10 feet of the Manifestation that are not aberrations must succeed on a DC 12 WIS save at the start of their turn or have disadvantage on attack rolls until the start of their next turn. Creatures immune to the frightened condition are immune to this effect.

Void Touch. *Melee Spell Attack:* +7 to hit, reach 5 ft., one target. *Hit:* 18 (4d6 + 4) cold damage. The target's HP maximum is reduced by the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its HP maximum to 0.
