Old School RuneScape Leagues VI adds Demonic Pacts, runs through June 10

Leagues VI gave Old School RuneScape players a new reason to clear the calendar: Demonic Pacts landed on April 15 and runs until June 10, giving mobile and PC players eight weeks to chase boosted progression, rare drops, and cosmetic rewards on separate league worlds.

The biggest change is the Demonic Pacts system. Instead of leaning only on the usual relic-powered rush that defined earlier Leagues, this season adds an all-new skill tree built around specialization. Jagex says the pacts let players master different combat styles much earlier than they would in the base game, which pushes buildcrafting and role choice deeper into the season. In practice, that means more room to commit to a plan early and less need to wait for standard account progression to open up the fun.

Everyone starts from scratch on a brand-new character, with the league running in its own worlds away from the main game. Jagex also built in faster pacing through boosted XP, with the official announcement calling out 5x starting XP and unlimited run energy, plus relics, combat masteries, explosive loot, and demonic cosmetic rewards. Trophy Points earned during the event convert into exclusive cosmetics, so even a short run through the season has a clear payoff beyond the combat grind.

The structure of the world map is just as important as the new combat system. Players begin in one region and unlock more by completing tasks and earning points. Community and official league materials point to Varlamore as the starting region, with Misthalin inaccessible in this league. Karamja is the first area unlocked, followed by three more regions chosen by the player, which keeps the early route tight and forces sharper decisions about where to build a path.

Echo Bosses return as the endgame carrot, and they are not just decorative difficulty spikes. Players need an Echo Orb from the normal boss to unlock the tougher version and its rewards, making the season’s progression loop about preparation, execution, and a final push into the harder variants. That fits the whole design of Leagues VI, which Jagex says returns after a two-year break and is themed around Yama, with Yama’s Lair serving as the starting point and launch pad for the season.

For returning mobile players, the appeal is immediate: the same event is live on iOS and Android, with cross-platform progression across Old School RuneScape on PC, Steam, and mobile. If you want a short-term grind with a hard deadline, a fresh character, and a real shot at unique rewards before June 10, this is the kind of seasonal reset that can swallow a few evenings fast.
