- Face Yama, the formidable Master of Pacts as the latest boss challenge
- Claim rare rewards including Demon Tallow and Grimoire Pages upon victory
- Discover new mining and smithing opportunities within the expanded Chasm
Old School RuneScape's newest update plunges players deeper into Great Kourend's turbulent politics and infernal underworld, where an ancient, wrathful force has awakened. The Chasm of Fire now hosts Yama, Master of Pacts - a fire-wreathed minotaur demon who's been biding his time, building power for this very confrontation.
This content continues the narrative from A Kingdom Divided (post-Royal Titans questline). Those who faced Yama's Judge in 2021 knew the conflict wasn't truly resolved. The true menace reveals itself - complete with towering horns, blazing wings, deadly hooves, and a devastating two-handed axe. Yama commands his fiery zealots, the Disciples, who fight with suicidal devotion.
Designed for elite adventurers, this battle requires quest completion, maximum combat stats, and Best-in-Slot equipment. The encounter supports both solo and group play. Victors gain access to exclusive rewards: Demon Tallow for crafting powerful Surge Potions, Chasm of Fire Teleport Scrolls, mysterious Grimoire Pages, and other secret treasures.

The Chasm now boasts expanded features, including a specialized mining and smithing section where players can extract Crimson Lovakite ore. This rare material crafts Oathplate armor, a formidable end-game set that makes exploration worthwhile even for non-boss hunters.
