Voice of the Void

Actions

Multiattack. The Voice uses 1 of its 4 non-attacks abilities, it then makes 8 khopesh attacks.   Voidling's Khopesh. Melee Weapon Attack: +18 to hit, reach 10 ft, one target. Hit: 14 1d8+10 slashing + 14 1d8+10 force + 14 1d8+10 untyped damage.

Non-attacks

Nightmare Veil. (recharge 6-8) The Voice emits a 60-foot-radius cloud of condensed darkness centered on itself, which lasts for 30 seconds.
While active, the Voice regains 26 4d12 HP at the start of its turn and makes 16 khopesh attacks each turn.
However, it can't use Maddening Presence, Corrupting Touch, cast spells, or move beyond the Veil.
If a force would move it outside the veil, it teleports to the center of the veil instead.
Additionally, the Veil counts as magical darkness for Darkvision and lowers the range of true sight by half. This does not affect Voidlings.   Maddening Presence. Each creature of the Voice's choice that is within 120 feet of it must succeed on a DC 30 Wisdom saving throw or become frightened for 1 minute. While frightened in this way, a target is also disturbed, acting as if under the effects of the confusion spell. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the Voice's Maddening Presence for the next 5 minutes.   Fold Reality. (Spell) The voice reaches out and bends the fabric of the material plane.

A 60-foot cube within 100 feet of the voice becomes spatially distorted for 2 minutes.

Any creature in the area when the spell is cast is pushed to one side of the cube (voice's choice which side).

All sides of that cube are treated as portals to the direct opposite side of the cube, while the area within the cube is treated as though it doesn't exist.

Any creature that passes through the cube (including any that enter the "portals" and any move when the spell is cast) must make a Con save or take 33 6d10 force + 33 6d10 untyped damage.

Any Non-voidling with less than 20 INT, that looks at the cube for more than 2 rounds must make a Wis save or become compelled to enter the cube.

  Corrupting Touch. (recharge 2-3) The Voice infects a creature it can touch, causing it to make a Con save.
On a fail, it's infected with a magic disease called Void phage.
See The Null Ocean, Far Realms page for details on the disease.
