Spears are offensive weaponry that provides burst damage. Spears have an attack range of 450. There are seven different spears.
Four spears (Basic, Iron, Steel, Dark) are constructed in the Armory, and the other three (Poison, Refined Poison, Ultra Poison) are constructed in a Witch Doctor's Hut. Some spears have a 60% chance of recovery after throwing, so it is wise to keep an inventory slot open if using spears. Doing this ensures you will be able to pick it up quickly and easily.
You can carry as many different types of spears as your inventory allows. Each spear has it's own stack limit and cooldown. The spears all share a general cooldown. For example, if you throw a Steel Spear you will still have to wait 8 seconds to throw any other spears you are carrying.
