Traits

Aura of Madness

The Aberration emits an aura of insanity in a 20 ft. radius. Any creature that starts its turn within the aura must make a DC 21 Wisdom saving throw or succumb to madness for 1 minute. While maddened, they roll a d6 to determine their action: (1-2) Attack the nearest ally, (3-4) Attack themselves, (5-6) Attack the nearest enemy.

Actions

Multiattack

The Vortex Aberration makes two attacks: one with its Disrupting Pseudopod and one with its Mindrend Split.

Disrupting Pseudopod

Melee Weapon Attack: +14 to hit, reach 15 ft., one target. Hit: 30 (4d10 + 8) bludgeoning damage. The target must succeed on a DC 21 Wisdom saving throw or be filled with uncontrollable terror, taking 28 (8d6) psychic damage and becoming frightened until the end of the Aberration's next turn.

Mindrend Split

The Aberration splits into two figures of itself temporarily, confusing foes. Ranged Psychic Attack: +14 to hit, range 60 ft., all creatures within a 20 ft. radius. Hit: 36 (8d8) psychic damage and the target must make a DC 21 Intelligence saving throw or be unable to discern friend from foe, attacking randomly for one round.

Chaotic Eruption

The Vortex Aberration releases a pulse of chaotic energy in a 30 ft. radius. Each creature within range must succeed on a DC 21 Constitution saving throw or take 45 (10d8) force damage and be knocked back 20 feet.

Bonus Actions

Fluid Form

The Vortex Aberration can move through a space as narrow as 1 inch wide without squeezing. Its form becomes intangible and unpredictable, making its movement a chaotic blur.

Legendary Actions

Legendary Actions (3 per round)

Warp Space

The Aberration momentarily alters reality around it, causing difficult terrain within 30 feet.

Echoing Horror

Triggers a maddening echo in the mind of a creature, forcing a DC 23 Wisdom saving throw. On a failure, the creature takes 26 (6d8) psychic damage.

Unravel Reality (Costs 2 Actions)

The Aberration tears a rift in space-time, dealing 50 (10d10) psychic damage to each creature in a 20 ft. line originating from it, and causing wild surges of magic to swirl erratically in the area.

Description

A bubbling mass of chaos, the Vortex Aberration is a twisted manifestation of pure insanity. Its colossal purple form perpetually shifts and distorts, with no two glimpses of it appearing the same. Its translucent, gelatinous body undulates in a perpetual dance of madness, colors swirling within it in a wild cacophony that defies logic. It emanates a palpable aura of terror, warping the minds of those who dare to look upon it. Its presence is a fracture in reality, bleeding unpredictability into the world around it.

Lore: Born from the void between realities, the Vortex Aberration is feared as a sentient vortex of chaos. Scholars speculate it exists to unravel the fabric of sanity, offering a glimpse into the mind-bending chaos that lies beyond the veil of reality.
