Polearms are some of the biggest weapons in the game, and as such can do very high damage at a very low cost. On the downside, it’s hard to use most of them unless you have a very large sized race and even then some are hard to use unless mounted.
Polearms include: harpoon, short spear, javelin, boar spear, bardiche, long spear, fauchard, trident, pilum, voulge, ranseur, glaive, scythe, gisarme, halberd, pike, and lance.
