A trident is a military one-handed melee weapon in the spear weapon group.[AV:9]

A trident is a heavy thrown weapon, so a character can throw it to make ranged attacks, using Strength instead of Dexterity for ranged basic attacks. It is also a versatile weapon, so medium characters may wield it two-handed to deal 1 extra damage. Small characters must wield it two-handed, and they deal no extra damage for doing so.

Ardents, avengers, barbarians, battleminds, fighters, paladins, rangers, wardens, and warlords are proficient with all military melee weapons, including the trident.

Other classes do not have proficiency with the trident as a class trait, but any character can become proficient by taking a Weapon Proficiency feat.
