Weave Explosion

A brilliant explosion of pure magic flashes in a 120-foot radius centered on you. Each creature within range must make a Constitution saving throw. On a failed save, a creature takes 40d12 force damage and is petrified. On a successful save, it takes half as much damage and isn't petrified by this spell.

A creature dropped to zero even if they passed the save is petrified.

The caster must make a DC 25 Constitution Saving Throw. On a failed save, the caster dies. On a successful save the caster is reduced to 0 but is in stable condition with 4 points of exhaustion.

This spell dispels any other magic in its area that was created by a spell.
