The Trident is a long polearm that deals immense thrust damage and is a fairly good weapon from horseback. It isn't as useful on foot beyond stopping a cavalry charge, but the units that wield this weapon still make their presence felt on the battlefield. While it does possess a swing attack, the damage is negligible. However, the Trident does possess among the highest thrust damage of all polearm weapons.
The Trident can be sometimes found in merchant shops, but it's easier to locate these weapons by looting the bodies of those who use them.
