Design: Wand of Lightning Bolts [4, 5, 2]
Made from turned glass, an Adamantium core, and painted with copper and zinc leafing, the Wand of Lightning Bolts is our second attempt to develop a battle spell that an individual wizard could cast by himself. The wand must be charged beforehand, which is the simple task of building a lightning rod tower and calling down the Hammer of Allah on it. Each wand can carry a single charge and unleash a modestly powerful lightning bolt that could fry a single man, cannon, or multiple birds (if they're close together). The bolt always terminates at the ground, limiting its range to Close - or Medium range, if the wizard is flying.
The wand is difficult to aim, and the lightning often arcs off in random and surprising directions. Wizards who use the wand must stand a great distance apart to avoid friendly fire. Like normal lightning, we have yet to figure out how to control the powerful force of nature absolutely, and on rare occasion the over-eager bolt will shatter the wand as it leaps towards the ground, maiming the wizard. This is relatively rare, however, and our mages have taken to wearing thick, cumbersome leather gloves on their casting hand to prevent being mutilated by the glass shards. The lightning will slowly fade in the glass prison, and Wands of Lightning have a shelf-life of a couple days before they must be recharged.
Because the wands are relatively easy to fabricate and charge, they are merely Expensive.
