The skill system undergoes a revolutionary transformation with its modular approach to ability customization. Each skill gem now offers multiple specialization paths that fundamentally alter how abilities function in combat. A simple fireball spell might be enhanced to leave burning ground, split into smaller projectiles, or transform into a sustained beam attack. This unprecedented flexibility allows players to tailor their skills to match specific playstyles and combat situations, creating truly unique character builds.Itemization embraces a sophisticated new philosophy through its intelligent loot system. Equipment now features contextual properties that activate based on character builds and combat approaches. The crafting system has been enhanced to provide more deterministic paths to powerful items while preserving the excitement of discovery. This balanced approach respects player time investment while maintaining the depth that defines the Path of Exile experience.
