Flames roar across your body, shedding bright light in a 30-foot radius and dim light for an additional 30 feet for the form's duration. The flames don't harm you or your equipment. Until the form ends, you gain the following benefits:
- You are immune to fire damage and have 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. Each creature in the line must make a Dexterity saving throw. A creature takes 4d8 fire damage on a failed save, or half as much on a successful one.
