Wake of Kabyrizhad

A burst of thunder forming a line 100 feet long and 5 feet wide blasts out from you in a direction you choose. Each creature in the line must make a Constitution saving throw. A creature takes 6d10 thunder damage on a failed save, or half as much damage on a successful one. Creatures, constructs, and objects made of earth and stone take an additional 2d10 thunder damage.

When the ground or structures made of earth or stone are impacted by the burst, a tunnel of diameter equal to the burst width is carved.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the width of the line increases by 5 feet for each slot level above 6th.
