Total annihilation

You compress the very fabric of reality into a singular, unstable point before releasing it in a cataclysmic burst that mimics the fury of a falling star.

​The Ground Zero (100-foot Radius)

​The spell centers on a point you can see within range. A blinding flash and a searing heatwave incinerate everything within a 100-foot radius sphere. All non-magical structures, buildings, plants, and animals in this area are instantly reduced to ash. The sheer force of the blast carves a 20-foot deep crater into the earth.

​Each creature in this area must make a DC 20 Dexterity saving throw.

• ​On a failure: A creature takes 15d10 + 40 fire damage and 10d10 force damage. Additionally, they are blinded and deafened for 1 hour.
• ​On a success: A creature takes half as much damage and is not blinded or deafened.

​The Shockwave (200-foot Radius)

​Immediately following the central explosion, a massive pressure wave surges outward. All creatures within a 200-foot radius of the center (excluding those in the Ground Zero zone) must make a DC 16 Dexterity saving throw.

• ​On a failure: A creature takes 10d10 + 20 force damage and is deafened for 20 turns.
• ​On a success: A creature takes half as much damage and is not deafened.

​

​Caster’s Peril: Upon completion, the caster must make a DC 18 Constitution saving throw. On a failure, they gain 2 levels of exhaustion, or 3 levels on a Natural 1. On a Natural 20 (or 19 if the caster possesses a feat that lowers critical thresholds), the caster gains Advantage on the Dexterity saving throw required to resist the spell’s own shockwave.

​Note: Due to the 2-action casting time, you must maintain concentration until the start of your next turn (or use your Action and a Surge) to complete the preparation.
