Greg O’Sullivan focused on improving reliability and balance in the WorldOfDarknessXIII/World-of-Darkness-13 game repository during March 2025. He addressed a critical bug in the ability stat logic, ensuring that the target’s mental stat is now correctly compared against the caster’s social stat for Hellweaving and Kiai abilities. This fix, implemented in DM and leveraging his skills in bug fixing and game development, aligned the mechanics with the intended game design and prevented unintended player advantages. While no new features were added, Greg’s targeted debugging contributed to a more balanced gameplay experience and demonstrated careful attention to system integrity.
