Breath Weapon | Bonus Action

Each creature along a 5 x 30 foot line must make
a saving throw of 8 + your Dexterity modifier +
your proficiency bonus.
A creature takes 2d6 damage on a failed save, and
half as much damage on a successful one. The
damage increases to 3d6 at 6th level, 4d6 at
11th level, and 5d6 at 16th level.
