Walker Reid expanded role-playing options in the WorldOfDarknessXIII/World-of-Darkness-13 repository by adding Salubri bloodline support for Anarch roles, specifically enabling Bouncer, Emissary, and Sweeper positions. He achieved this by updating configuration data, modifying the allowed_bloodlines lists within job definitions to include Salubri, and ensuring all changes remained backward compatible. Working primarily with DM language and leveraging skills in game development and role-playing game mechanics, Walker established a reusable approach for future bloodline-based features. The work was scoped to data files, minimizing risk, and was deployed without major bugs, reflecting careful change management and a focus on maintainability.
