A Fire Pot is an utility item created with the tinkering skill which can be used to set hexes on fire. When thrown, it sets the desired hex on fire and three adjacent hexes. It can be thrown to an occupied hex.
The fire will spread to other hexes for the next two turns. The fire will then extinguish from the centre to the outer flames. Any unit inside the hexes on fire, will get the burning status effect and lose 20-30 hitpoints per turn.
It can also be used to burn down barricades. As far as known, the smoke or the flames themselves have no effect on the accuracy of arrows and bullets.
