Ashardalon's Burst

The billowing flames of a dragon blast from your feet, propelling you forward 30 feet in a direction of your choice. This movement does not provoke opportunity attacks.

You leave a line of fire along the path, any creatures in your path must make a dexterity saving throw or take 2d6 fire damage on a failure, or half as much on a success.

If you end this movement in another creatures space, both you and the creature must make opposed strength saving throws, the loser takes 2d6 force damage. You also take this damage if your movement is ended early by colliding with an object.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, fire the damage increases by 1d6 for each slot level above 1st.
