Ash Step

You are engulfed in flames, and stomp the ground. The flames disperse and spread a 100 ft in every direction and immediately turn any grass or wildlife or creatures of 1/4 CR or lower into ash. Wherever the ash is within 100 ft. of you, you can teleport to the ash. The spell can be moved using a wind type spell, however, you can only teleport if you are within the 100 ft. circle. Furthermore, you have advantage on Dex throws. 

You can use a lvl 6 spell slot to up the CR to 1/2, you can also use a lvl 9th spell slot to up the CR to 1, as well as increasing the range to 200ft. as well as making Ash Step both a bonus action as well as a reaction, taking only half if you save on a disadvantage DC 20 Dex save.
