About this project
What it does
The Custom Companion Management App began as a Blink Dog manager and is structured to support multiple D&D companion types, including pseudodragons, tressyms, flumphs, and homebrew additions. It ties one or more companions to a player character and guides advancement through legal level-gated choices.
Ability modifiers, proficiency, saves, attacks, skill bonuses, and other derived values are calculated from the current state instead of being stored as fragile numbers. Everything persists locally, while data-driven definitions keep rules for each companion inspectable and extensible.
