Trident

A trident is a type of spear designed for use in fishing. It has decent defensive capabilities but is not an especially deadly weapon, though it is nearly as effective as many other spears and can be thrown a short distance. The trident is a two-handed weapon and its combat effectiveness is modified by the Spear skill. "Trident is a triple-pointed spear.  Trident is commonly used in fishing.  When used as a combat weapon it attacks no better (sometimes worse) than a spear, but its three prongs enable its user to catch, block and break enemy weapons; this gives it a somewhat better defensive capacity."
