Shatterspark

The Shatterspark is a war hammer. The majority of the hammer is forged of a dark, shiny, iridescent-blue metal. Its handle mostly appears overgrown with faintly luminous, bright blue, teal and cyan flowers attached to thin dark blue vines, which upon closer inspection are made of a strange metal weave. Upon striking a target, it releases an explosive blast of electricity, scorching the area around it and especially anything it hits. When the spike on the back of the hammer strikes a target, it produces a constant, steady charge as long as it is in contact. The machinery involved with the electrical aspect of the hammer is mostly hidden within the handle.

The head has more flowers carved into it, with the spike on the back appearing like a spiked vine. The handle is mostly a lighter weight metal as compared to the head of the hammer, with the whole of it being excellently balanced.
