Astral Geyser

A concentrated beam of gravitational force and astral energy being forcibly combined by ripping a hole through space in front of the caster, compressed into a 120 foot long and 5 foot wide beam designed to erase any form of matter caught within it from existence. Each creature in the line must make a Dexterity saving throw. A creature takes 6d6 force damage and 4d6 radiant damage and is pushed up to 30 feet away from you on a failed save, or half as much damage and a 10 foot push on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the force damage increases by 1d6 for each slot level above 5th.
