Decided to build a full Foundry VTT v13 system for Vagabond RPG instead of using Custom System Builder (CSB). Reasons: (1) Variable crit thresholds per skill require Active Effects which CSB handles poorly, (2) Dynamic spell casting with delivery+duration+damage customization needs custom dialogs, (3) Future multiclass support requires proper class-as-item architecture, (4) Parchment theme with accessibility needs full CSS control. Project location: /mnt/NV2/Development/vagabond-rpg-foundryvtt. See PROJECT_ROADMAP.json for 98 tasks across 11 phases.
