RuneScape’s first League, Catalyst, launches on September 15, bringing an eight-week ruleset that turbo-charges progression and hands players overpowered relics inside a fresh, members-only server.
Starting at 09:15 UTC on 15 Sept 2025 and running until 12:00 UTC on 10 Nov 2025, the Catalyst League re-balances the entire game loop, cutting grind times and layering new mechanics Jagex will detail next week. Membership grants instant access, and the studio has confirmed the League contains zero microtransactions, focusing purely on skill, speed and experimentation. A full rules post is expected imminently, giving min-maxers the data they need to plot their race for top-tier relic power.
