Worked on the pf2e repository for FoundryVTT, focusing on stabilizing the core healing logic within the Ambient Magic system to enhance gameplay reliability and balance. Addressed a critical bug by correcting the healing calculation in the Administer Ambient Magic feature, ensuring that hit point recovery now scales accurately with actor level. This fix improved player experience by reducing confusion around healing outcomes and supporting consistent combat mechanics. The work involved precise JSON manipulation and a strong understanding of game development principles, with changes delivered through a single, well-documented commit that maintained traceability and upheld code quality standards throughout the process.
