Based on Fire Lances Of The Ancient Hyperzephyrians
Let’s start with the obvious: NO THEY’RE NOT JUST GUNS! Everybody can put guns into D&D. Hell, everyone already has! That’s boring, moving on.
The Lances are fired with a stabbing motion, at which point they release a small projectile with a thunder crack, that sets the thing it hits on fire (as greek fire or similar, can not be put out, burns underwater). Because of it’s method of activation, aiming the Fire Lances at long distances is all but impossible. The Fire Lances actually have a bayonet attached to their business-end so they’re useful even when empty.
Once the Lance is out of charges, reloading is done by fire aswell. Thrown into a campfire (or fire of similar size) and waiting for the fire to die down will leave the weapon fully recharged.
Damage: 1d6 + 1d4 fire damage for 1d4 rounds OR 1d6
