Spiky Ball

Spiky Balls are heavy metal Nonexplosive Consumables category spheres with sharp points on them that are dropped by Goblin Peons. 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. Once thrown, a Spiky Ball cannot be returned to the player's inventory. This is also very useful against groups of enemies.

A good strategy is to place multiple balls along a hall where mobs will walk through maximizing the damage of the item. On the other hand, The Spiky Ball is most likely a walking Mine.
