Trash Pulls to Boss 1

Pull 1 — Pathing Taskmaster

From the entrance, head down all the stairs and stop at the last landing (before the final set of stairs). Everyone except the tank stays on this landing with their back to the rock wall (by the flaming blue torch). The tank stands at the top of the last landing facing the trash.

Wait for the pathing Mordath Taskmaster to approach from the left, then pull him to the top of the steps (face away from the group). Burn him down — adds spawn at 80% but die when the Taskmaster dies, so ignore them.

Pull 2 — Overseer Group

Mobs: 1 Overseer, 1 Slave-Culler, 2 Condemned Soldiers, 3 Enslaved Nurnhoth

Lock down the Slave-Culler (Lore-master or Burglar). Kill order: Overseer > Soldiers > Nurnhoth > Slave-Culler.

Pull 3 — Double Taskmasters

Mobs: 2 Taskmasters

Each tank pulls one and separates them. Burn one down, then the other.

Pull 4 — Taskmaster(s)

Mobs: 1 Taskmaster (sometimes you can get both from Pull 3; if not, repeat the same approach)

Burn down one at a time.

Pull 5 — Large Mixed Group

Mobs: 1 Overseer, 1 Captain, 2 Slave-Cullers, 1 Defiler, 1 Tracker, Enslaved Nurnhoth (inactive unless aggroed)

Lock down the Defiler and 1 Slave-Culler. Kill order: Overseer > Captain > Slave-Culler (free) > Tracker > Slave-Culler (locked) > Defiler (locked). Remove corruptions throughout.

Pull 6 — Largest Trash Pull

Mobs: 1 Taskmaster, 1 Defiler, 1 Overseer, 1 Captain, 2 Slave-Cullers, Enslaved Nurnhoth (some inactive)

Lock down the Defiler and both Slave-Cullers. Off-tank stays on the Taskmaster. Kill order: Taskmaster > Overseer > Captain > Slave-Cullers > Tracker > Defiler (locked). Remove corruptions and wounds throughout. Slow the Slave-Cullers if possible — the Marked buff deals massive damage (7 million in T2) but only lasts 12 seconds, so slowing them gives the targeted player time to move away.

Pull 7

Mobs: 2 Bloated Pit Crawlers, Nurnhoth, 1 Shadowy Remnant

Pull 9

Mobs: 2 Abyssal Maggots, Nurnhoth, 1 Shadowy Remnant

Pull 10

Mobs: 1 Deathless Watcher, 1 Ritualist, 2 Assassins, 1 Warrior, 4 Zealots

Pull 11

Mobs: 1 Deathless Watcher, 2 Ritualists, 2 Assassins, 2 Warriors, 4 Zealots

Boss 1: The Spoiled of Eye (The Twins)

Main Bosses

Two bosses: The High Priest of Khokali and The High Priestess of Dauraga (commonly called "The Twins"). Key mechanics:

• Tanks must keep them separated — when too close they gain a shield preventing damage and begin regenerating morale
• Damaging one boss deals roughly equal damage to the other
• Most groups focus all DPS on the Priestess

Mini Bosses

Mini bosses spawn at health thresholds:

Health %	Mini Boss	Notes
75%	Gurmaush Stone-hide (Rhino)	Zergs targets. On death, debuffs players with Blood Sickness — 10% morale damage every 2s, spreads to nearby players on expiry
50%	Thornethril the Tainted (Spider)	Drops Tainted Bile poison clouds — 20% morale damage every 2s. Often gets stuck in side room. On death, spawns spiderlings that root players
25%	Falchranc the Hewn (Ent)	On death, buffs the Twins with periodic heal bubbles that must be burned quickly

• T1: Main tank grabs all mini bosses (low damage)
• T2: Main tank holds Rhino and Ent; secondary tank grabs Spider if loose

Devoted Supplicants

Spawn roughly every 40 seconds (2 at a time on T2). They take 30 seconds to reach the altar. Can be stunned/slowed but not CCed otherwise. When they reach the altar they sacrifice themselves and buff the Twins' damage.

• T1: Ignore this mechanic (buff is minimal)
• T2: Stagger them with stuns/slows so tanks don't eat a double buff simultaneously

Blood-Spirits

At 70% boss health the High Priest says: "Sauron shall be reborn in blood." 4 Blood-Spirits spawn, with 4 more every 75 seconds (max 8 at a time — don't kill them).

• Low damage unless you are within 5m when they induct (spinning red circle at their feet)
• They don't move while inducting — simply walk away
• Cannot be interrupted

Tip: Scroll your camera way out so you can see 360 degrees around you. Most wipes happen because players don't notice Blood-Spirits inducting behind them.

Altar Mechanic

Starting at 85% health and roughly every 60 seconds:

1. The High Priest says: "The Eye is cast upon you, [player name]" — that player is teleported atop the altar. Healers must get them to full health before they can break free (keep trying to jump off)
2. Simultaneously, the High Priestess says: "Silence!" — everyone is hit with a fear. Pot or remove immediately

---

T1 Strategy

1. Two tanks start the fight and separate the Twins (tanking position doesn't matter in T1)
2. Move at least 5m from Blood-Spirits when they induct (red circle)
3. Stay out of green puddles (Spider)
4. Heal altar targets to 100% and pot the group fear
5. Ignore Devoted Supplicants
6. All DPS on the Priestess until she dies
7. Burn the Priest (may have residual morale)
8. Kill mini bosses: Stone-hide > Ent > Spider

T2 Strategy

Challenge: The Order of Death — Kill all 3 mini bosses within the blood pools (red water) before the main bosses die.

1. Two tanks separate the Twins and tank them in a blood pool
2. Stun/slow one of the two Devoted Supplicants; tanks prepare defensive cooldowns (Juggernaut, Pledge, Shield of Doom, To Arms, etc.) for the DPS buff
3. Move 5m from inducting Blood-Spirits; stay out of green puddles; heal altar targets and pot fears
4. All DPS on Priestess until just under 25% (Ent spawns — last mini boss)
5. Tank pulls the Stone-hide to the blood pool and group burns it down. It must die in the blood pool. Use incoming healing debuffs on the boss just before it dies. Fellowship manoeuvres help position kills
6. Tank pulls the Ent to the blood pool — same approach
7. DPS the Priestess to roughly 9% morale, then switch to Spider
8. Tank pulls the Spider to the blood pool — burn it down (must die in the pool)
9. Switch back to the Priestess and finish her off

Boss 2: The Deathless Warden (Sagrog)

One main boss with Embittered Shadow-guard adds spawning roughly every 60 seconds.

Core Mechanics

Corruption Bubble: Starting at 90% health and periodically thereafter, Sagrog says: "Ulur ilzu-ûr, drû-glob!" and gains a corruption shield (-70% incoming damage). The group must remove 25 corruptions to break it.

Wages of Fear: If you are not facing the boss when he uses this, you will be feared and he gains positional damage advantage — one-shotting most squishies. Face the boss at all times.

Hateful Shadow: Pottable wound debuff — 23,212 damage every 3 seconds for 18 seconds.

Spiteful Javelin: Pottable wound debuff — -75% incoming healing and -75% outgoing healing for 12 seconds.

Shadow Debuff: Periodically applies +500 shadow to the group (roughly every 30 seconds). Must be removed immediately — nearly any attack will one-shot players with this debuff. Burglar's Antidote (raid-wide) is ideal; Muster Courage is second best.

Embittered Shadow-guards (ESGs): Spawn every 60 seconds (1 on T1, 2 on T2). Do not kill them — on death they spawn two lights that randomly zerg, and leave puddles dealing morale-based damage.

The Unseen Spear: Spawns after the first corruption bubble is removed (relevant for T2 challenge only).

T1 Strategy

• Guards make excellent off-tanks (easy single-target pulls and fast corruption removal); Captains make good main tanks
• Main tank pulls the boss; all DPS burns while the tank positions
• Off-tank stays with the group initially, helping remove corruptions when the bubble appears
• When the first ESG spawns, the off-tank moves to a separate position (always facing the boss) and tanks the ESG there, cycling through corruption removal
• Main group alternates between DPS phases (no corruptions) and corruption removal phases (bubble up). One person should call out transitions
• Pot wounds ASAP
• Off-tank continues to pick up ESGs as they spawn, removing corruptions from each
• Ignore the Unseen Spear in T1

T2 Strategy

Challenge: A Light in the Darkness — Heal the Unseen Spear to 100% health after Sagrog is below 1 million morale, before killing Sagrog.

• Same tank setup as T1 (Guard off-tank, Captain main tank)
• Same DPS/corruption rotation, but ESGs spawn in pairs (2 per wave)
• Off-tank will accumulate 6–8 ESGs by the end; if they reach 10 ESGs, start kiting. If the off-tank drops below 20% health, ESGs use Execute and will one-shot them
• Burglar and/or Lore-master should help remove corruptions on ESGs if needed
• Unseen Spear healing: Keep 1 dedicated healer on the Spear at all times. A Beorning is the best choice (percentage-based heals); Minstrels can work but are less ideal

Beorning tips for the Unseen Spear:

• Place Mark of Grimbeorn on the Spear as soon as it appears
• Tooltip the Spear (hover and press H) — it goes invisible during corruption phases but remains selectable if tooltipped
• Focus on three things: healing the Spear, applying Bees/Armour Crush on Sagrog, and removing corruptions
• Once the Spear is one proc away from full heal, remove the Mark and wait until DPS is ready. When called, re-apply the Mark and heal to full

Boss 3: The Master of the Seven (Fingar the Greedy)

Three-phase fight with a 25-minute enrage timer — after 25 minutes Fingar enters Wrath of the Great Worm (+900% damage).

Phase 1: Chained (100%–65%)

Fingar is chained down during this phase.

Key Mechanics:

• Will of the Ring corruption — remove ASAP or Fingar gains Will of Urya (prevents morale-to-power conversion, critical for T2 challenge)
• Ignore Watchers of Glurnakh (T1)
• Ignore the Devoured that spawn (T1)
• Stay out of fire puddles

Phase 2: Unchained (65%–25%)

Fingar breaks free. Position with the tank at Fingar's head and DPS at his hindquarters. Keep the tank in heal range.

Main Attacks:

Attack	Notes
Tail Lash	Rear cone attack
Flames of Angband	Fire breath — at 50% morale he starts turning to face players; occurs every 45 seconds thereafter
Belly of the Beast	Every 35 seconds. Distributed damage. Fingar rises on all fours and shakes, then belly-flops. When he rises, everyone except the tank must bunch up to split damage. Return to positions after the knockback

At 30% morale, King Vaskmun Greytooth spawns.

Phase 3: The King (25%–0%)

King Vaskmun Greytooth spawns. The tank grabs him (minimal damage). Continue the Phase 2 strategy while finishing Fingar.

---

T1 Strategy

Phase 1:

1. Have a Burglar use Diversion at the start of the fight
2. If no Burglar: melee should avoid engaging Fingar directly (use ranged attacks only). Ranged DPS stands as far back as possible (use the rock on the ground as a distance guide)
3. DPS Fingar until he breaks free (65%)
4. Ignore Watchers, Devoured, and fire puddles

Phase 2:

1. Position tank at head, DPS at hindquarters
2. Bunch up for Belly of the Beast (every 35 seconds)
3. Continue DPSing until Phase 3

Phase 3:

1. Tank grabs King Vaskmun
2. Finish Fingar
3. Kill remaining mini bosses: Stone-hide > Ent > Spider (if applicable)

T2 Strategy

Challenge: The Power of the Dwarf Rings — Kill all Watchers of Glurnakh before Fingar hits 65%, burn through his power bar within 100 seconds for Will of Urya, and defeat King Vaskmun before Fingar reaches 3%.

Phase 1:

1. Burglar uses Diversion at the start
2. Melee use ranged attacks only; ranged DPS stands max distance
3. DPS Fingar until first adds spawn. The Devoured randomly zerg and explode on death (morale damage to nearby players) — DPS them if overwhelming, or use Bane Flare/CC
4. Kill all Watchers of Glurnakh — Devoured stop spawning once Watchers are dead
5. Return to Fingar until Phase 2

Phase 2:

1. Tank at head, DPS at hindquarters. Stay out of big red circles (falling ceiling damage)
2. Remove Will of the Ring corruption immediately — burn through his power in under 100 seconds for the Will of Urya conversion
3. Bunch up for Belly of the Beast every 35 seconds
4. If Will of Urya is completed successfully, at roughly 60% health gold coin cyclones begin pathing randomly (persist until the end). Being hit throws you through the air — position so they knock you away from the boss rather than into danger. Ranged classes should stand near the back/sides of the arena
5. Stop DPS at 9 million morale on Fingar and switch to King Vaskmun

Phase 3 (Challenge):

1. Group up and follow the off-tank who kites King Vaskmun in large circles — this keeps you ahead of the coin cyclones
2. At 40% of the King's health, adds spawn. At 30%, damage is distributed to his soldiers
3. Lock down Rune-carvers when they spawn (Burglar/Lore-master) — keep them locked for the rest of the fight
4. Watch for Soldiers — they reflect damage (kite them or remove corruptions)
5. When the King dies (try to be on the opposite side of the arena from the main tank), Fingar becomes immune briefly while doing 3 fire breaths that consume sections of the room
6. As soon as Fingar is vulnerable again, burn him to 3% as fast as possible (coin cyclones stop at 3%)
7. Finish Fingar

Recommended Consumables

The Abyss of Mordath is a long raid with high sustained damage. Full consumable uptime is non-negotiable for T2.

Recommended Consumables

Consumable	Example	Purpose
Cooked Food (crit)	Luxurious Roasted Oryx Shank	Primary stat food for your class
Trail Food	Pot of Mûrai Honey and Oats	Trail food — mitigation buffs
Battle Scroll	Scroll of Mûrai Battle Lore	Offensive mastery buff
Warding Scroll	Scroll of Mûrai Warding Lore	Defensive mitigation — critical for tanks and off-tanks managing ESGs
Hope Token	Mûrai Edhelharn Token	Hope buff — counters Abyssal Darkness dread from Deathless Watchers
Athelas Essence	Greater Mûrai Athelas Essence	Emergency morale after Bursting Boils or Blood Sickness
Celebrant Essence	Greater Mûrai Celebrant Essence	Power sustain — essential during long corruption removal phases
Enhancement Rune	Enhancement Rune +4, Lvl 151	Extra LI item levels for DPS and healing output
Shield-spikes	Mûrai Westernesse Shield-spike Kit	Shield-spike for tanks (match damage type to content)

Tip: Bring at least 3 stacks of each consumable — the Abyss is long and wipes mean rebuffing. The 25-minute enrage on Fingar means every stat point counts. Coordinate a Splendid Mûrai Feast or Durable Umbari Feast before each boss pull.
