Spear Trap

The Spear Trap is a trap found naturally in the Jungle Temple. When activated, it launches a spear in a straight line that can pierce an infinite number of enemies and retracts upon hitting a block or reaching its maximum range of 19.5 blocks. It has a cooldown of 3 seconds between firings ( 3.33 or 31/3 seconds).

Spear Traps can be rotated 90° with a hammer.

Tips

 * Rarely, Spear Traps will spawn outside the temple and can be harvested. They work well against the Goblin Army or, in some cases, the Pirate Invasion or Blood Moon.
 * They are good for battle arenas.
 * When actuated, these can be used as a very efficient way to kill off bosses, or clear waves in events like Pumpkin Moon and Frost Moon, easily.
