Voidheart Vortex creates a powerful, swirling vortex of dark energy that devours matter and magic alike.

Vortex Creation: When you cast this spell, choose a point you can see within range. A vortex forms at that point, with a 40-foot radius. The vortex moves 10 feet in a random direction at the start of each of your turns.

Matter and Magic Consumption: Each creature in the vortex's area when it appears, or that enters it later, must make a Dexterity saving throw. On a failed save, a creature takes 6d10 force damage and is pulled 10 feet toward the center of the vortex. On a successful save, a creature takes half damage and isn't pulled.

Spell Disruption: Spells of 5th level or lower cast within the vortex or into the area are automatically nullified. Higher-level spells require a caster level check against your spell save DC to succeed.

Void Gateway: Each round the vortex exists, there is a 5% cumulative chance that it will tear a temporary rift to the void. Roll a d20 at the end of each of your turns; on a roll of 20, a rift opens. Creatures within 20 feet of the vortex are pulled into the void, potentially lost forever.

Gravity Distortion: The intense gravitational pull of the vortex makes the area difficult terrain, and flying creatures have disadvantage on saving throws against the vortex's pull.

When the spell ends, the vortex collapses, potentially ejecting anything that was pulled into the void at a random location within 1,000 feet.
