Azure Flame Arrow

You fire the weapon used in the spell’s casting and make a ranged weapon attack against a creature in range. On a hit, the target suffers the weapon attack’s normal effects, and you can cause the arrow to burst into a wave of ghostly azure flames causing every creature you can see within 5 feet of it to make a dexterity saving throw. The on a fail, the creatures take fire damage equal to your spellcasting ability modifier.

At Higher Levels. At 5th level, the ranged attack deals an extra 1d4 fire damage to the target on a hit, and the fire damage to the other creatures increases to 1d4 + your spellcasting ability modifier. Both damage rolls increase by 1d4 at 11th level (2d4 and 2d4) and 17th level (3d4 and 3d4).
