The fire thrower is a unique ranged troop, using grenades of Greek fire to set his surrounding alight from short range. He has an area attack, meaning that he can lob fire over walls and short towers, effectively attacking targets on the other side.

Fire throwers can light pitch ditches on fire without Braziers, and they can start a fire anywhere and keep it going indefinitely. Certain landscape features (notably bushy shrubs) can be set alight, although their number is not usually great enough or in a place that can be manipulated in a defensive or offensive manner. The throwers themselves have high resistance to fire, allowing them to safely move through flames.

While very effective on the ground, they prove very bad against elevated targets: they cannot damage units on towers or walls as their grenades bounce back (fire will still spread where they land). Furthermore, their low speed, short range and high cost make them suitable rather for defensive purposes.
