Tungsten Ballsack

A guitar appears out of thin air, and creates a bolt of lightning forming a line 50 feet long and 5 feet wide in any direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 1d6 lightning damage on a failed save, or half as much damage on a successful one.

The lightning ignites flammable objects in the area that aren't being worn or carried.

At Higher Levels. the damage scales for every 4 levels (level 4 is 2d6 level 8 is 3d6 level 12 is 4d6 level 16 is 5d6 and level 20 is 6d6)

This cantrip may only be casted once per day
