Harpoon

Harpoons were spear-like weapons used to hunt marine animals.

Description
The metal head of a harpoon was fixed to a wooden shaft. The head was often pointed and hooked to increase the weapon's grip in flesh and cause more harm. The harpoon was connected to a rope which the thrower could release or increase tension on to reel a target in or throw it off balance. A typical harpoon weighed and could be purchased for 20 gp.

History
Anchors, who were specialty priests of Umberlee, favored using harpoons in combat.
