Developed and integrated the Tavern Fighter trait within the Rotwood-Vale/Ratwood-2.0 repository, focusing on expanding role-playing and gameplay options for tavern-centric sessions. The work involved implementing trait-based buffs and status effects using DM, ensuring these enhancements were linked across tavern areas and specifically applied to the Barkeep job. This approach established cross-module cohesion by connecting traits, status effects, and area interactions, laying groundwork for future quest and event scenarios. Throughout the process, clear traceability was maintained through detailed commit references. The project demonstrated skills in game development and role-playing game mechanics, emphasizing modular design and future extensibility.
