Contributed to the PathOfBuildingCommunity/PathOfBuilding repository by delivering an enhanced defense calculation feature aimed at improving damage mitigation accuracy in game modeling. The work involved implementing a conditional calculation function in Lua, ensuring that armor defense types are processed before miscellaneous calculations to maintain correct dependency order. This approach addressed miscalculations related to spell suppression when evasion mastery was active, resulting in more reliable in-game damage assessments. The developer focused on algorithm optimization and code hygiene, including correcting a logic typo to reduce edge-case errors. Their contributions demonstrated proficiency in Lua programming and game development within a complex calculation pipeline.
