The Grand Summoners x Solo Leveling collaboration features iconic characters like Sung Jinwoo, Igris, and Shizuku Mukaisaka as playable units with specialized Dark and Physical damage kits. The event, prominent in the Japanese (JP) server, focuses on high-damage output, dark-type synergies, and unique mechanics modeled after the series, including "shadow" mechanics for Igris and fast-acting arts for Jinwoo.
