Hydaelyn

You create a fiery typhoon at a location you can see within 120 feet of you. All creatures in a 20-foot radius must succeed on a Dexterity saving throw or take 4d6 fire damage and 4d6 thunder damage, or half as much on a success. The affected area continues to burn for 1 minute, becoming difficult terrain. A creature entering the space for the first time or starting their turn in the area takes 1d10 fire damage. If cast using Enhanced Ninjutsu, the damage increases by an additional 4d6 fire damage. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6+1d6 for each slot level above 2nd.
