A wizard is a very reclusive, wise man familiar with the ways of magic. He is one of the few remaining mortals capable of shaping magic and casting spells. Most importantly, however, he can bind his spells into magic scrolls, which even those unfamiliar with magic can use.
In return for a few common items, a wizard will offer to create magical Scrolls. These scrolls capture the wizard's power in a form that anyone can use. Due to their reclusive nature, only the most experienced of adventurers can locate a wizard.
