Violent Lightning/Instant Flash

After entering the Thunder Breathing state, you focus the power of lightning into your legs and dash, nearly instantly crossing a certain distance while simultaneously performing a slashing attack with your weapon. A creature hit takes regular weapon damage +8 lightning damage.

When you cast this ability using a spell slot of 2nd level or higher, the range goes up by 10ft and the damage increase goes up by 1d8 for each slot level above 1st. At slot levels 3 and 5 one may target 2 and 3 creatures respectively, as long as the complete distance crossed does not exceed the spell range.
