Yama Guide-A Deep Dive Into RuneScape's Newest Duo Boss

Today we're going deep into the fiery depths of the Chasm of Fire to break down everything you need to know about Yama, the brand-new endgame duo boss that just dropped on live servers following its reveal at RuneFest 2025.

Whether you're a PvM veteran or a curious explorer looking to add this fight to your bossing log, this comprehensive guide will help you secure your first KC, understand every mechanic,get more OSRS gold and get on the grind for uniques, the pet, or even just that sweet flex of beating one of OSRS's newest and most intricate bosses.

Accessing the Fight: Requirements and Setup

To face Yama, you must first complete the A Kingdom Divided quest. While that's the only hard requirement, let's be honest - this is no mid-game encounter. You're going to want:

·Base 90 combat stats

·Piety & Augury unlocked

·73 or 83 Agility (for the critical boss shortcuts)

·Despite being a demon, Yama is not slayer taskable, and even perks like Like a Boss won't let you get him as an assignment. That's one common stream question out of the way.

Gear Recommendations

This is not a fight you want to enter with budget or rag gear. While melee is viable, Magic is currently the dominant method due to safety and consistency.

Bare Minimum Magic Loadout:

·Purging Staff (must-have for orbs)

·Emberlight

·Demonbane spell access via Arceuus spellbook

·Accessories like the Alter Ring, Vernic Defender, Rancor, and optionally a Saturated Heart (or just bring Forgotten Brew + Super Restores)

·Best-in-Slot Magic Loadout:

·Full BiS Mage gear

·Shadow or Tumeken's for added DPS (if budget allows)

·Magic Damage-boosting accessories

·You don't need a full melee switch unless you're taking a hybrid approach. If you can only afford one item, Purging Staff > Emberlight due to the utility with demonic orbs.

Getting to Yama

The fastest way is using Fairy Ring code DJR near the Chasm of Fire, then:

·If you have 83 Agility, use the chain shortcut.

·With 73 Agility, take a slightly longer route.

·Without either, you'll need to descend using cage elevators - a time-consuming path you'll want to avoid.

·Training Agility for these shortcuts is highly recommended if you plan to farm Yama regularly.

Fight Difficulty & Duo vs Solo

Duo Mode: Surprisingly forgiving. Easier than Nightmare.

Solo Mode: A significant step up in challenge. The final phase can be more demanding than Fosani's Nightmare.

If you're up for an intense, mechanically rich fight, solo Yama is a superb test of your PvM skills.

Phase-by-Phase Mechanics Breakdown

Let's dive into what makes this fight tick. Yama transforms into a massive demon and begins attacking right after initiating the challenge. Here's what to watch for:

Phase 1:

·Five Glyphs appear in the arena.

·Glyph color dictates prayer:

·Red Glyphs: Pray Range → stand on glyph → switch to Mage prayer

·Purple Glyphs: Pray Mage → stand on glyph → switch to Range

·Yama's basic attacks follow visual cues:

·Mage Attack: Flame rings & fire animation

·Range Attack: Subtle shadow swirl & dark arm animation

·Specials to watch for:

·Flame Walls: Diagonal black and horizontal red flames

·Step on the corresponding glyph color to nullify the effect.

·Standing on a used glyph makes it temporarily unavailable.

Demonic Orbs:

·Spawn randomly and must be dealt with quickly.

·Purging Staff + Mark of Darkness = best solution

·Kill both orbs before they heal Yama or hurt you.

·Alternative (less effective): Kill one orb and step on the glyph matching the other orb's color to nullify the damage.

Intermission at 66% HP:

·Yama teleports you to one side of the arena.

·Jump rocks diagonally to dodge incoming fireballs.

·On the other side, attack a demon that caps your max hit regardless of gear.

·Use Magic first, then switch to Melee with Emberlight.

·You can even step under the demon to bait self-damage, but it's not required.

Phase 2:

·Similar to Phase 1 with glyphs and prayers.

·Red Glyph = Meteor: Pray Range and stand right next to it. Meteor = one-hit KO if you're in the center.

·Purple Glyph = Minor AoE: Nothing crazy, just block damage.

·Black Flame Walls now stack - dodge two at once or rely on purple glyph if overwhelmed.

·Another intermission follows when Yama hits 33% HP.

Phase 3 - Final Phase:

·Yama begins with the opposite style from Phases 1/2.

·Glyphs are gone - you'll have to react with prayers and positioning alone.

·He alternates between Mage and Range with no visual glyph guidance.

·New mechanic if using Magic:

·Yama drops 3 falling rocks after each basic attack:

·Horizontal: Step up or down

·Vertical: Step left or right

·Diagonal: Move one tile perpendicular to the slant

·Using melee allows you to skip this mechanic entirely.Tips for Progress and KC

Firstfew kills will be overwhelming. Here's a priority list:

1.Prayer switching

2.Dodging rocks

4.Avoiding flame trails

6.Managing orbs

8.Solo runs will take longer, so don't hesitate to stock up on food & potions and learn the mechanics gradually. If you have a reliable duo partner, the fight becomes significantly easier - you'll alternate glyph responsibility, manage orb aggro, and damage shared HP bar demons during intermissions.

Loot & Uniques

Like most new bosses, Yama's loot table is evolving, and many tradeables are already dropping in price.

Key Drops:

·Oath Blade Armor: High offensive bonuses, less Strength. Can also be crafted using Oath Blade Shards.

·Soulflame Horn: Boosts team melee DPS.

·Forgotten Lock Box / Dossier: Contain random loot and contracts.

·Demonic Tallow Barrel: Used to make new Surge Potions.

·Ether Catalyst: Allows Ether Rune creation.

·Diabolic Worms: Speeds up Anglerfish gathering.

·Casm Teleport Scrolls: Quick access to the boss area.

·And of course, the pet.

·Because armor can be crafted, market saturation is already occurring. Don't expect insane GP/hr unless you snag a unique early.

Final Thoughts

Yama is one of the most engaging and satisfying bosses added to Old School RuneScape in recent memory. The complexity and learning curve may be daunting at first, but the fight rewards mechanical mastery, team coordination, and flexibility between combat styles.Also,you can buy OSRS gold to grow up quickly.

Whether you're hunting the pet, showing off your PvM skills, or chasing the next best-in-slot magic armor, Yama is well worth your time. Just make sure you're prepared, agile, and ready to get dunked on - because this demon doesn't mess around.
