Elin's True Flame

You exhale and a baseball-sized ball of fire forms in your hand, ready to be thrown at a target. Roll a ranged spell attack. A creature hit by the spell that has resistance to fire is treated with no resistance. Any creature with immunity to fire is treated as if being resistant to fire. A target takes 6d6 fire damage on hit and must roll a Dexterity saving throw. On a failure the creature ignites for 1 minute, taking 1d6 fire damage (halved if they are immune to fire) at the start of its turns. A creature can reroll the save at the end of its turn, ending the effect on a success.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 4th.
