Aura of Immolation

You bathe yourself in bright red and orange flames. At the end of your turn, any creature within 10 feet of you must make a Dexterity saving throw. A target suffers 2d10 fire damage on a failed save, or half as much damage on a successful one. Until the start of your next turn, if a creature moves within range for the first time, it also falls under the effects of the spell.

At higher levels: When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 for each slot level above 2nd.
