The fiery depths of Old School RuneScape are about to get hotter. On May 14th, players will face off against Yama, the Master of Pacts-a brand-new high-level boss located deep within the Chasm of Fire. With difficulty scaling through a contract system similar to Tombs of Amascut (TOA) invocations, this update is poised to redefine what it means to be late-game ready. Whether you're a seasoned PvMer or a curious adventurer looking to make the leap, OSRS gold, this guide will walk you through everything you need to know to prepare for Yama's arrival.

Who Is Yama and Where Do You Find Him?

Yama is a massive demon and is expected to be one of the largest and most complex boss encounters yet in OSRS. With concept art describing him as 7x7 tiles, he rivals the scale of end-phase Verzik or even the Wardens in TOA. You'll be fighting him in a huge arena-likely requiring quick movement, positioning awareness, and possibly a fair amount of stamina potion chugging.

Yama's lair will be in the Chasm of Fire, likely on the bottom floor or even deeper. The quickest route is via the Fairy Ring code DJR. If you haven't completed the Lumbridge Elite Diary, now's a great time to knock it out-this lets you use fairy rings without a Dramen staff.

The Contract System: Make It Your Fight

Yama introduces an optional difficulty system via contracts, akin to invocation mechanics from TOA. This means you can tailor the difficulty to your experience level and goals-whether you're dipping your toes into PvM or going for max-challenge loot. Jagex confirmed that the hardest versions of Yama will exceed the difficulty of Awakened Desert Treasure II bosses, so now's the time to start brushing up.

If you're looking to simulate what you'll face, practice bosses like Awakened Vardorvis, Fasanis' Nightmare, and Desert Treasure II's Awakened bosses. All of these share DNA with Yama's design-developed under the watchful eye of Mod Arcane, who's known for mechanically-rich encounters.

Gear Preparation: Bring All Three Combat Styles

The most interesting part about Yama? We don't know for sure which style will be best-in-slot. And that's intentional. Here's what we do know:

·Yama is a demon, meaning Demonbane weapons like the Scorching Bow, Emberite, and especially the Purging Staff will likely shine.

·Jagex specifically noted in their April 9th QoL blog that Purging Staff's accuracy was being corrected while testing Yama. That's no coincidence.

·A follow-up blog (Poll 84 Batch 2) straight-up told players to "dust off those Demonbane weapons."

·So what should you do?

Prepare gear for all three combat styles-Melee, Ranged, and Magic. This includes:

·Magic: Purging Staff + Mark of Darkness + Demonbane spells

·Ranged: Scorching Bow, Venator Bow (for AoE?), chins

·Melee: Scythe of Vitur, Inquisitor's, or Slash/Crush alternatives

·Historically, Jagex buffs underused gear with new content. The Purging Staff might finally have its moment in the spotlight.

Potions, Pre-pots, and Herblore Prep

You're going to want your pre-fight routine on lock, especially if Yama ends up being high-paced and punishing. Here's what to stock:

·Stamina potions: Movement is likely key in such a large arena.

·Divine potions: Super combat, Ranging, and Magic.

·Prayer-restore options: Sanfew serums, Super restores, Prayer potions.

·Antivenoms: Extended for longer fights.

·Holy Water: No spoilers-just trust the process.

·Blood Fury with Blood Shard: For passive healing, especially valuable in solo or duo formats.

·Chugging Barrel: Combine up to 5 potions for one-click pre-pots. A major QoL tool for bossing.

·New Surge Potions - Crafting Requirement

The new Surge Potions, dropped by Yama, are untradeable and require 81 Herblore to make. You'll need:

·An unfinished Torstol potion

·A drop from Yama

·These Surge potions will likely grant Special Attack Energy, making them essential for max-DPS rotations.

TL;DR: If you don't have 81 Herblore, go get it. Now.

Mod Arcane and the Mechanics You Can Expect

Mod Arcane has been behind nearly every boss with minion mechanics in OSRS. Fasanis, Kefri, Ba-Ba, Zebak, Araxxor-you name it. What do they all have in common? They spawn adds.

Expect Yama to have:

·Minions or summoned entities mid-fight

·Possible AoE attack opportunities

·Movement-based mechanics (big arena, maybe dodging AoEs or chasing phases)

·To prepare:

·Practice AoE options: Barrage spells, Venator Bow, Chinchompas

·Get used to dodging mechanics and target-switching from TOA and DT2

·Yama is meant to test not just your gear but your PvM fundamentals.Find Your Team - Now, Not Later

One of the biggest mistakes you can make is waiting until release day to find a team. Don't be that player standing at the Chasm entrance in a Fire Cape hoping to tag along.

If you want to be taken seriously:

·Get your Infernal Cape

·Network before release day

·Join PvM clans

·Hang around FFA Raid worlds

·Add skilled players from recent bossing sessions

·Soloing might be possible in lower contract versions, but for higher-level encounters, you'll want trusted teammates who know what they're doing.

Pre-Release Market Tips

Items that will likely increase in price as the update goes live:

·Blood shards (for Blood Fury)

·Stamina potions

·Sanfews and Antivenoms

·Holy Water

·High-tier gear across all styles

·Unfinished Torstols (for Surge potions)

·On the flip side, expect gear investments like Torva, ancestral, and scythe to stabilize or even dip post-release, as players cash out. You can grab them during that dip window if you're quick.

Final Checklist Before May 14th

·Unlock Fairy Ring DJR (Lumbridge Elite recommended)

·Stock up on Stamina, Divine, and Antivenom potions

·Prepare gear sets for Magic, Melee, and Ranged

·Train Herblore to 81 minimum

·Get a Chugging Barrel for pre-pots

·Complete the Inferno or at least avoid showing up in Fire Cape

·Practice Awakened DT2 Bosses

·Reach out and find teammates before launch

·Load up on Blood shards and Torstol potions

·Remember to have fun and take breaks

Conclusion: A New Era of Bossing Begins

Yama is shaping up to be one of the most exciting and flexible bosses in Old School RuneScape history. With variable difficulty through contracts, grow up with buy RuneScape gold, multiple viable combat styles, and the potential revival of underused weapons like the Purging Staff, this encounter rewards those who come prepared.
