The Tesla club is a modified version of the sledgehammer. As such it is technically a tool, rather than a weapon, and is found in the tools section of inventory. This club works like a melee weapon, but also can deal extreme damage via a blast of purple electricity emanating from the tip when wielded during a critical hit. The Tesla club is said to be derived from the science of the Tesla coil.
