Enyaki's Static Tube

Through a clever pulley that twists a piece of twine like a coil, the device has stored kinetic energy. When the switch is released, a bit of fleece races around a glass rod (on the inside of the cylinder), charging it with static. No more nasty discharges or the need for two hands.

Use of this device reduces the casting time of a lightning spell from 1 action to a free action. After each use, the spring has to be re-wound which takes a full round. The static tube is in the final stages of testing, and has a 5% chance of failure each time it is used.

Campaign lore: This item was developed by the gnome Enyaki, as part of his research for Project Deatchwatch.
