An otherworldly entity of immense, formless darkness that swallows light, sound, force and life. it is a writhing, dense mass of nothingness, a palpable absence beyond understanding or definition. The Void Elemental is a cosmic force that disrupts the very fabric of reality, a vortex dragging everything into its vast and empty embrace.
Habitat. The Void Elemental roams the vast emptiness of space until it is drawn to places where planar breaches have caused the boundaries between dimensions to grow thin, creating areas of cosmic instability.
Motivation: To absorb excess magic, light and matter in the universe and restore equilibrium to the void of space.
Void Effects. The Void Elemental absorbs light and sound, creating a 60-foot area of darkness and silence around it. Furthermore it distorts the region up to 5 miles around it, obscuring the stars and deepening shadows.
Null Magic Zone. An area within 60 ft. of the Void Elemental is devoid of all magical effects. Spells cast within 100 ft. have a chance to be nullified (as dispel magic DC 18). The Void Elemental gains hit points equal to twice the spell level of a nullified spell.
Dissonant Whispers: Unsettling, unintelligible whispers echo in the minds of creatures within 60 ft of the Void Elemental causing 3d6 psychic damage dues to an overwhelming sense of despair (frightened). Those affected must make a Wisdom saving throw at the start of their next turn.
Temporal Stasis: Time is distorted within a 40-ft radius, the speed of all targets in the area is halved, they take a -2 penalty to AC and Dexterity saving throws, and can't use reactions.
Force Absorption. Whenever the Void Elemental is subjected to force damage, it takes no damage and instead gains temporary hit points equal to the force damage dealt.
Ethereal Distortion. Ethereal creatures within 60 ft. are drawn into the Material Plane.
Vortex. Ranged Spell Attack: +6 to hit, range 60 ft. Hit: 23 (3d10) force damage. Creatures within 60 ft. of the Void Elemental must succeed on a DC 16 Strength saving throw or be pulled 30 ft. towards the Elemental.
Suffocating Aura. Creatures within 20 feet of the Void Elemental must succeed on a DC 16 Constitution saving throw at the start of their turn or be unable to breathe. They can repeat the saving throw at the start of each of their turns.
Tactics
Lurker: Using its Void Effects to cloak its approach, the Void Elemental strategically positions itself in areas of Darkness before surprising its enemies.
Nullify Magic: The Void Elemental seeks to render magic useless and thus weaken its adversaries.
Battlefield Control: Using its mobility, Vortex and Suffocating Aura to control enemy position and make them suffer.
