This versatile class blends summoning demons from the Burning Hells, casting chaotic fire and magic spells, and engaging in mind-controlled melee combat with eldritch weapons. Warlocks can levitate their right-hand weapon, allowing them to wield two-handed weapons alongside an off-hand item like a shield - a unique mechanic enabling unprecedented build flexibility.

The Warlock features three skill trees: Chaos (fire and magic casting with sigils), Eldritch (hexes, melee manipulation, and support), and Demon (summoning and binding hellspawn). Below is a full breakdown of all 30 skills, including descriptions and synergies where applicable. Note that exact mana costs, levels, and prerequisites are still being refined in early Season 13 testing, but these provide the core functionality.
