Stynger

The Stynger is a ranged weapon that drops off the boss Golem. The ammo it uses is Stynger Bolt which initially drops off the Golem as well, and can later be purchased from the Witch Doctor and Arms Dealer. The shots do an area of effect explosion which will deal damage to anything in the explosion radius. Arching shrapnel is thrown from the explosion, each causing additional explosions smaller than the original but with the same base damage.
