Blades in the Dark: Deep Cuts is a 118-page expansion for the Blades in the Dark roleplaying game — containing a treasure trove of lore, setting material, and alternative mechanics I've developed over the years for use in Blades campaigns.
The first part expands on the setting of the game, including:
    27 factions, providing new lore and crew opportunities
    Over 100 heritage and background packages to flesh out the characters and the setting even more
    13 new innovations in technology to reflect ongoing industrial-age advances, including new rare and restricted technology for nefarious Scoundrels to get their hands on
Also included is a new concept I'm calling a "catalyst" — which is a world-shaking event that expands and alters the setting of the game, providing new avenues for intrigue and adventure, as well as opportunities and scores for every crew type.
The second part contains 6 modular rules systems, including:
    More flexible and impactful Harm & Trauma rules
    A modified Advancement system to customize the rate at which characters progress
    Diceless Downtime, with modified Vice, Healing, Crew Development, and other systems, as well as a system for Debt
    A modified Load system that's more tied to the fiction while remaining simple and easy to use
    A new Action system, which overhauls and streamlines the action resolution mechanics to empower players even more and speed up the process of play
The whole book is packed with tons of lore, gameable details, plug-and-play systems, GM tools, crew opportunities, and new artwork to take your Blades in the Dark games to the next level.
