Yama’s debut isn’t just another boss drop—it’s a direct sequel to 2021’s “A Kingdom Divided,” where adventurers toppled Yama’s Judge. Now, the fire demon himself rises, gathering strength and minions in the Chasm of Fire. Expect a showdown steeped in lore, with Gielinor’s fate smoldering in the balance.

OSRS Yama in the Chasm of Fire
Prepare to face Yama deep in the Chasm of Fire, Old School RuneScape’s latest endgame challenge.

Whether you’re a lone wolf or rallying your clan, the Yama encounter is built for both solo and team play. The spoils? Demon Tallow (essential for Surge Potions), the Chasm of Fire Teleport Scroll, and a coveted Grimoire Page, among others. Beyond the boss, a newly opened mining and smithing area lets players unearth Crimson Lovakite—forgeable into the formidable Oathplate armour set, a serious contender for Best in Slot for crafters and combatants alike.

Venture deeper to mine Crimson Lovakite and craft the formidable Oathplate armour.

Access is strictly for those who’ve conquered “A Kingdom Divided” and maxed out their combat prowess—making this update a love letter to OSRS’s most dedicated. For these players, Yama isn’t just another boss: he’s a fresh, high-stakes PvE challenge in a game where every major addition is polled and player-powered.

This new content is classic OSRS: community-driven, lore-heavy, and fiercely challenging. The instanced mining area and new Best in Slot gear echo trends from other MMOs but are distinctly RuneScape thanks to their player-chosen roots and nostalgic flair. Even after more than a decade, the game’s fiery spirit clearly hasn’t cooled.

Bring friends for extra firepower, or tackle Yama solo for all the glory—and loot.

Will Yama ignite a new era for Old School RuneScape? For those chasing the next big challenge (and some seriously spicy loot), this is the update to beat. Whether it’s enough to lure back lapsed legends remains to be seen, but one thing’s clear: the Chasm of Fire is burning brighter than ever.

TL;DR: OSRS’s Yama boss brings brutal fights, unique loot, and new crafting for high-level players who’ve finished “A Kingdom Divided.” Brave the flames, reap the rewards.
