8th Level

• A bright streak flashes from your pointing finger to a point you choose within range and then blossoms with a low roar into an explosion of flame. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 fire damage on a failed save, or half as much damage on a successful one. The fire spreads around corners. It ignites flammable objects in the area that aren’t being worn or carried.

16th Level

• When you inscribe the Ild rune on your body, you radiate heat and light. All creatures within 10 feet of you take 4D6 fire damage. All creatures within 20 feet of you take 2D6 fire damage. Waves of heat radiate from you, and you are considered obscured. Unless your enemies can see through heat distortions, you gain a +4 to your armor class. You become resistant to cold and energy damage. You gain 40 temporary hit points. These effects last up to 10 minutes. You can only benefit from this one time per day. Too much risks consuming yourself in the heat you generate. Any remaining temporary hit points vanish at the end of 10 minutes.
