Zombie Arm

A severed zombie arm with autoswing. It hits harder than the tungsten broadsword you would otherwise be holding at that stage, and the cost is reach: you have to be close enough that the thing you are killing is already touching you. As an early sword it is a genuine upgrade if the drop happens to come your way, and not worth farming for if it does not.

Swinging it flings bits of zombie about once a second. Turning off blood and gore removes the effect outright rather than swapping in the usual puff of smoke that other gore effects fall back on.

In expert worlds you will occasionally run into a zombie carrying one. Those hit harder and swing further than a normal one, and killing that specific zombie does nothing to improve your odds of getting the weapon. Look closely at the sprite and there is still a shackle fastened to the wrist, which is the other rare thing zombies drop.
