Spear Trap

A Spear Trap is a type of trap that you can find in the Jungle Temple after beating Plantera, they are quite common and on desktop and console  versions of Terraria can be rotated by 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.
 * In single-player, Spear Traps inflict the Frostburn-debuff if the player wears Frost armor.
