Eternal Void Abyss

Effect: You call upon the absolute destruction of the Void, releasing an overwhelming wave of energy from within. All creatures within a 60-foot radius of you must make a Constitution saving throw. On a failed save, each creature takes 40d8 necrotic damage as the Void tears at their very essence. Creatures reduced to 0 hit points by this damage are disintegrated, leaving no trace behind, as if erased from existence.

On a successful save, a creature takes half damage and suffers no additional effects. The caster is immune to the effects of this spell and is unaffected by the damage or disintegration effect and is immune to necrotic damage for 10 minutes. The Void energy is so powerful that even the environment around you is consumed by its force, turning the ground to ash, leaving only an empty, desolate space in the wake of the Abyss.

Lore & Flavor:

Eternal Void Abyss is the ultimate manifestation of void energy—an eruption of the Void’s all-consuming power that disintegrates not only the body but also the very essence of the target. Those who dare cast this spell invite the deepest and most dangerous forces of entropy, calling forth the power of oblivion itself. Once cast, it leaves nothing but ruin in its wake. The spell is said to be used by beings of immense power—gods, ancient sorcerers, or creatures of the Void who wish to annihilate everything within their grasp. Casting it is a supreme act of power, as the Void itself can never be contained once unleashed. The caster stands unaffected by the spell's destructive force, but the cost is high, as the very fabric of reality is bent and torn around them.
