From publisher blurb: Call to Arms is a book line for players and gamemasters alike. Each book focuses on a different type of item, expanding rules for those items and adding everything from new mundane and magical examples of the item to new character options related to the item. Call to Arms: The Magic Satchel offers new and old methods to help characters with inventory management by introducing a new mechanic to simplify the process for characters as well as new magic items that help provide a player with just the right thing at the right time, or at least make it easier to be sure they have the space to have it on hand. This is in addition to the usual cursed, mythic, and artifact items you can expect to see in a Call to Arms book.
