Burst Shot

You weave volatile magic into your weapon, causing it's next attack to detonate on impact. You brandish the weapon used in the spell’s casting and make a ranged weapon attack with it against a creature within its range. On a hit, the creature suffers the weapon attack’s normal effects and one creature of your choice within 5 feet of it takes fire damage equal to your spellcasting ability modifier.

This spell’s damage increases when you reach certain levels. At 5th level, the ranged attack deals an extra 1d6 fire damage to the target on a hit, and the fire damage to the second creature increases to 1d6 + your spellcasting ability modifier. Both damage rolls increase by 1d6 at 11th level (2d6 and 2d6) and 17th level (3d6 and 3d6).
