Tales of Tolgard
Scrolls can be of the arcane or divine varieties. Some spellcasters, such as wizards, can learn spell from scrolls. In the process of transferring the spell to their spellbooks, however, the scroll is used up.
These magic items can give a group of adventurers the edge they need to come out victorious. Strangely, though, scrolls tend to be much more uncommon on Material Plane than elsewhere in the multiverse.
