Volcanic Explosion

Volcanic pyre radiates in a 30-foot-radius, 60-foot-tall cylinder around you. Each  hostile creature in that cylinder must make a Dexterity saving throw. A creature takes 6d8 fire damage on a failed save, or half as much damage on a successful one. Every hostile creature that fails the save is shunted 15 feet upwards and away from the cylinders center. All nonmagical structures in contact with the ground within the area are immediately destroyed.

When you cast this spell, you can elect to create a 10-foot-radius safe haven centered around you, which remains undamaged by the effects of the spell.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d8 for each slot level above 4th.
