Bolt of Lightning

In-game description
"This bolt seems to crackle with energy as it is held in the hand. When shot from the crossbow, it seems to leap forward towards its target leaving behind an electric sulphuric smell. As it hits there is a crackle as the energy stored is released into the targets wound."
