Developed the Regicide aura feature for Warriors in the wowsims/sod repository, focusing on backend and simulation programming using Go. The work involved implementing precise activation logic at 20 stacks, deactivation upon trigger, and ensuring correct interaction with the Execute damage modifier. Stack progression and aura state transitions were handled to maintain simulation fidelity and accurate APL-driven behavior. The approach emphasized incremental, traceable changes with clear commit messages, supporting maintainability and reliability within the simulation module. No bugs were addressed during this period, with efforts concentrated on delivering robust feature logic and aligning cast conditions to match gameplay requirements.
