Elauria

Flames race across your body, shedding bright light in a 30-foot radius and dim light for an additional 30 feet for the spell’s duration. The flames don’t harm you, granting immunity to fire damage and resistance to cold damage. Any creature that moves within 5 feet of you for the first time on a turn or ends its turn there takes 1d10 fire damage. You can use your action to create a line of fire 15 feet long and 5 feet wide extending from you in a direction you choose, forcing creatures in the line to make a Dexterity saving throw, taking 4d8 fire damage on a failed save, or half as much on a successful one.
