Spiky Ball

Spiky Balls are consumable weapons that are primarily used as passive traps, by tossing them to the ground, where enemies who pass over them will take damage up to 6 times (after which the Spiky Balls vanish). If not destroyed, they will automatically vanish in 1 in-game hour(1 minute in real world). They can also be used as thrown weapons, but they have a very short arc and quickly fall to the ground. Spiky Balls are dropped by all Goblins in the Goblin Army, and can be purchased from the Goblin Tinkerer for each. The Goblin Tinkerer also uses them to defend himself.

Tips

 * Useful against groups of enemies, or bosses, if you can get them to charge you through a group of Spiky Balls, or fly/tunnel through them.
 * Especially useful against the Eater of Worlds, since all its segments continue emerging from the same point on the ground.
 * When wearing Frost armor, Spiky Balls will glow from the Frostburn effect and can serve as makeshift Glowsticks.
 * When thrown on the ground they can serve as an immobilizer to any monster without knockback resistance.
