Ashbolt

A streak of superheated air and red hot ash fires from your palm toward a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 fire damage, and for the duration of the spell the target takes 1d10 fire damage at the start of each of its turns. The spell ends early if you lose concentration or a creature takes an action to douse the fire.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the initial damage increases by 1d10 for each slot level above 1st.
