Spiky Ball

Spiky Balls are spiked metal consumable weapons that are dropped by any goblin in the Goblin Army or can be bought from the Goblin Tinkerer.

Spiky Balls can be thrown as a weapon, much like a Shuriken; however, they have a very short arc and quickly fall to the ground, where they continue to roll. On the other hand, they can be thrown very quickly, and each ball can hit up to five times before vanishing. Even when the balls come to a stop, they can still do harm to enemy monsters and players in PvP mode. This is also very useful against groups of enemies, or bosses if you can get them to charge you in such a way that they either pause in a group of Spiky Balls, or fly/tunnel through them. Once thrown, a Spiky Ball cannot be returned to the player's Inventory.

A good strategy is to place multiple balls along a hall where mobs will walk through maximizing the damage of the item.

It is also effective on the wall of flesh, as the spiky balls do a large amount of damage in great numbers
