Rocket, Incendiary (Average)

You have a +1 bonus to attack rolls made with this enhanced rocket launcher ammunition, which deals 2d6 kinetic damage on a hit. This bonus is in addition to any bonuses granted by the weapon. Additionally, hit or miss, the rocket then explodes, setting the ground beneath it in a 15 foot radius ablaze for 1 minute. When a creature enters the fire or starts its turn there it must make a DC 16 Dexterity saving throw. On a failed save, the creature takes 4d8 fire damage or half as much on a successful one. A construct makes this save with disadvantage.
