Yama, the New Boss, Emerges in Great Kourend in Old School RuneScape

Author:Kristen Update:Jun 13,2025

Yama, the Master of Pacts, emerges as Old School RuneScape’s latest and most formidable boss yet—a fire-wreathed minotaur demon who has long been building power in the Chasm of Fire. Now awakened, Yama brings with him a host of new challenges and rewards for players daring enough to face him. Defeating this infernal beast grants access to unique items such as Demon Tallow, used in crafting powerful Surge Potions, and Grimoire Pages that enhance your magical capabilities. The Chasm itself has also received an update, now featuring dedicated mining and smithing zones where players can extract Crimson Lovakite and forge the new Oathplate armor set—perfect for those looking to strengthen their late-game progression.

A New Chapter in Great Kourend

Old School RuneScape's newest content plunges players back into the turbulent heart of Great Kourend, a land once torn apart by political strife and now threatened by ancient demonic forces. This expansion builds directly on the events of *A Kingdom Divided* and follows up on the aftermath of the 2021 encounter with Yama’s Judge. It turns out, that was merely a precursor to the real danger—one that now stands before you, horns blazing, axe raised, and ready for battle. Yama is not alone; he is supported by his loyal Disciples of Yama, a fanatical cult devoted to spreading fire and destruction across the land.

Challenging Combat & Powerful Rewards

The fight against Yama is designed for seasoned adventurers. A completed prerequisite quest, elite combat stats, and Best in Slot gear are practically mandatory for survival. Whether you choose to tackle the encounter solo or team up with friends, victory unlocks a variety of exclusive items. Among them: Demon Tallow for potion crafting, the Chasm of Fire Teleport Scroll for quick access, and several Grimoire Pages that offer meaningful boosts to spellcasting efficiency and damage output. Hidden surprises await those who delve deeper into the post-boss loot system.

New Crafting Opportunities in the Chasm of Fire

Beyond the boss fight, the Chasm of Fire now serves as more than just a battleground. Players can explore newly added mining and smithing areas, harvesting the rare resource Crimson Lovakite. This material allows for the creation of the Oathplate armor set, offering substantial defensive bonuses and becoming a coveted addition to any endgame setup. Even if raiding isn’t your thing, the Chasm remains a valuable destination for crafting-focused players seeking new materials and progression paths.
