Antimagic Ray
Tier 2 Epic conjuration
Casting Time: 1 action
Range: 120 feet
Components: V, S, M (four obsidian shards carved into cubes)
Duration: Instantaneous
You create prisons of crushing rock from the ground in four 15- foot cubes you can see within range. The cubes have an AC of 20 and 400 hit points and if destroyed leave behind difficult terrain in the area they occupied. Huge or smaller creatures completely within those areas must succeed on a Dexterity saving throw to avoid getting imprisoned, moving to the nearest unoccupied space outside of the spell’s area on a success. Creatures that are not completely inside a tomb’s area are pushed to the nearest unoccupied space. On a failure, creatures that completely fit inside the area are encased in the stone prisons and begin suffocating.
At Higher Levels. When you cast this spell as a tier 3 Epic spell, each cube created by this spell has 800 hit points instead of 400.
