Rocket Maul

One of Artificer Elyana's inventions, the head of this maul is made from blackened metal, and its front is sculpted to resemble a boar with large curved tusks. The back of the head is a large conical hole, inside which a small flame always burns. Clockwork gears and hoses run along the shaft to a canister of fuel at the end of the metal handle.

You gain a +1 bonus to attacks and damage rolls with this magic weapon. The weapon has a number of charges equal to your proficiency bonus. When you hit an enemy, you can expend a charge to activate the rocket in the head, dealing 9 (2d8) additional fire damage, or 13 (3d8) if the target is a Plant or Ooze.

If you have the Divine Smite feature, using one of the weapons charges counts as using Divine Smite. You can also choose to deal Fire damage with your normal smites, and Plants and Oozes take 1d8 extra damage from your smites.
