During October 2025, Gulbert Da worked on the wowsims/mop repository, focusing on enhancing combat simulation fidelity for Warlock pets. He developed and delivered a feature that recalibrated the minimum energy thresholds for the Imp and Succubus, ensuring their ability usage in simulations more closely matched intended in-game behavior. This adjustment improved the accuracy of simulation data used for Warlock balance decisions and provided a single, maintainable source of truth for pet energy tuning. Gulbert applied his skills in game development and simulation, utilizing Go to implement these changes, which deepened the reliability and traceability of pet behavior modeling.
