Wands of Lightning are highly unstable, at least in the early stages of their construction. Many an inexperienced caster has found his laboratory the site of a sudden squall or charged fog, having failed to speak the proper incantations in just the right manner. It is said that elder wizards have allowed tomes with faulty rituals to be circulated, hoping to indirectly teach some humility.
Wands cannot be equipped to any of your inventory slots. You may assign a wand to your quickslots.
