Afturburn

You move 120 feet in a straight line, leaving a plume of fire behind you as you go. While you are using this movement, you do not provoke opportunity attacks, you can move through the spaces of hostile creatures, and moving through difficult terrain doesn't cost you extra movement. If you move through or within 5 feet of a creature's space, that creature must make a Dexterity saving throw, taking 4d6 fire damage on a failed save, or half as much damage on a successful one. A creature can only be made to make this save once per round.
