Air and clouds coalesces in a roiling sphere between your hands then a rush of sound strikes forward forming a line 100 feet long and 5 feet wide, massive gravitational force compacting and hardening it into a solid piercing lance of thunder cast forth in a direction you choose. Each creature in the line must make both a Dexterity, and Constitution saving throw. Those creatures struck take 8d8 thunder damage and are deafened until the end of your next turn on a failed save, half as much damage with a successful Dexterity save, and not deafened with a successful Constitution save.

The thunderous sound made by the lance can be easily heard in all directions out to 1 mile.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 2d8 for each slot level above 5th.
