The book contains lore on each subclass, as well rules for playing them as a playable character or a non-playable character. Each subclass differs immensely from each other, and are primarily only unified by their connection to the Doctors Guild.

The Doctors Guild is what connects all the different doctor subclasses. Each doctor is licensed by the Guild, the guild also provides doctors with access to abilities, tasks, and items. The book includes a comprehensive lore on the Guild, and guides on how to use it in-game. 

Most Doctors are not as interested in the magic items that adventures normally covets, they simply have no use for them beyond their value. Doctors instead get their upgrades from the Guild Emporium, a massive boutique run by the Doctors Guild.

Every doctor subclass has their own tailor made doctor’s office. These offices will allow the doctor to expand their abilities and give more depth to the character. Upgrades to their office may be purchased from the Guild Emporium. The primary focus of the bag is not to enhance the doctor’s combat abilities, but rather their roleplaying abilities.

The Doctor’s bag, provided by the Guild, comes in three versions that become available as the doctor gains more experience. Common to the bags are that they all provide access to the doctor’s office, an extra dimensional space within the bag. Thereby, doctors are able to bring their profession with them on adventures.

Besides providing the rules for the Crit Cards, the book also contains an in depth look into the aftermath of players that have suffered loss of a limb or a broken bone. The book guides the reader on how to mitigate the damage done, and provides examples on how the player might turn the situation to their advantage.
