Ogron Hauler deals heavy tank damage, and should be faced away from the raid for Slag Breath. Overhead Smash will damage melee, while Ground Stomp damages the ranged.

Workshop Guardians debuff tanks with Grievous Mortal Wounds, and cast Spinning Blade that players must move out of.

Iron Flame Binders deal heavy damage with Lavaburst, sometimes at random targets.

Iron Slag-Shapers channel Rain of Slag, dealing very heavy AoE damage to the entire raid. This can be interrupted.

Ironworkers use Hammer Throw against their threat target, and cast Explosive Ore on random targets.

Darkshard Acidbacks come in swarms and will create Acidback Puddles that deal moderate periodic damage to players standing within them.

Darkshard Gnasher will cast Insatiable Hunger on players and chase them with Shattering Charge, dealing heavy damage and stunning all nearby players when the Charge completes. The Gnasher then deals heavy melee damage to the fixate target until fixate wears off. Fixated targets should run away quickly; movement speed boosts may be required.

Darkshard Crystalbacks throw Shard Volley at a few randomly-chosen ranged targets, dealing splash damage to players around them. The raid should spread out to minimize Volley damage.

Return to Table of ContentsOregorger Tips & Strategy

Oregorger begins the fight at 100 mana, and when he runs out of mana, he enters phase 2.

During phase 1, players should interrupt Blackrock Barrage, off-tanks must soak Acid Torrent, and ranged must move out of Retched Blackrock.

During phase 2, Oregorger enters a Rolling Fury, and travels throughout the encounter area in search of Blackrock Ore to eat.

Players must destroy Ore Crates to reveal the Blackrock Ore.

After Oregorger rolls over 10 un-boxed Ore, he will be full on mana and re-enter phase 1.

Phase 1 is where players can deal the most damage to Oregorger, as he is mostly stationary.

Blackrock SpinesBlackrock Barrage

The Barrage deals very heavy, unavoidable raid-wide damage, and should be interrupted.

Oregorger will cast Barrage three times, usually in a row, but sometimes other spells sneak in

The raid will need a rotation of at least three players to handle the interrupts

Backup interrupters may be useful in case a player wastes their interrupt on one of the other spells

Interrupters should be prepared to interrupt for the entire duration of Blackrock Spines

Acid Torrent

Oregorger will turn towards a random ranged player and shoot an Acid Torrent in their direction.

The first player this projectile passes through will take extremely heavy Physical damage.

All other players the projectile passes through will take a smaller amount of Nature damage.

The Nature damage portion is reduced dependent upon the first target's total damage reduction, including CDs and armor.

The current off-tank should stand between the boss and the ranged players, and soak the Acid Torrent projectile.

Soaking an Acid Torrent leaves a 20-second debuff that increases the damage of further Acid Torrents; tanks should swap roles after each Torrent.

Melee DPS should be sure not to stand near the off-tank, to avoid taking any Acid Torrent damage.

Ranged DPS and healers should stay stacked up so the off-tank can easily intercept the Acid Torrent.

Retched BlackrockExplosive ShardExplosive ShardAcid TorrentRolling Fury

He will roll through the various passageways in the encounter area, foraging for Blackrock Ore.

Players who are caught in Oregorger's path will take extremely heavy single-target damage and will be stunned.

Before Oregorger begins to roll, he pauses briefly and faces the direction in which he will move; players must simply get out of his way.

Additionally, Oregorger cannot return down the path he just took, meaning the space behind him is always safe.

At the end of each roll path, Oregorger will cause an Earthshaking Collision, dealing raid-wide damage.

Due to Hunger Drive, each subsequent Earthshaking Collision will deal more damage, so damage is heavier at the end of the phase.

Return to Table of ContentsTank Responsibilities

Face Oregorger so that the ranged group is to his side, not his back

When not tanking Oregorger, stand between the boss and the ranged group

The off-tank should use a personal CD when Oregorger uses Acid Torrent

Tanks should taunt off one another after each Acid Torrent, so that no tank soaks two Acid Torrents in a row

Acid Maw stacks will fall off on their own as tanks trade for the Acid Torrent mechanic

During the Rolling Fury phase, DPS the Ore Crates and avoid Oregorger's path

Quickly taunt Oregorger following the Rolling Fury phase, and move him into position in an area clear of Retched Blackrock pools

Return to Table of ContentsDamage-Dealer Responsibilities

Melee DPS must watch for Explosive Shard near them and move away to avoid being stunned

Ranged DPS should move out of Retched Blackrock, but avoid blocking any of the passageways entirely with these puddles

Ranged DPS should use personal survivability CDs to mitigate Acid Torrent damage

Interrupt Blackrock Barrage; set up a reliable rotation of 3 interrupters

During the Rolling Fury phase, move to your assigned location in the room and DPS nearby Ore Crates

Oregorger can be DPSed during the Rolling Fury phase, but avoid standing in Oregorger's path

Return to Table of ContentsHealer Responsibilities

The tank who is soaking Acid Torrent will take strong single-target damage, and may require an external CD to reduce its damage

The ranged pile will take heavy damage following each Acid Torrent; prepare AoE heals for these casts

Move out of Retched Blackrock and use personal survivability CDs to mitigate Acid Torrent damage on yourself

During the Rolling Fury phase, the raid will spread out; be sure all areas of the room have an assigned healer

Move to your assigned position and heal players killing Ore Crates, while avoiding standing in Oregorger's path

Use healing CDs towards the end of the Rolling Fury phases, when Earthshaking Collision damage is high

Great! Looking forward to using these. Question: How do you know about the trash mobs? Were they included on the Beta way back when? I thought beta people were only able to see the boss that was being tested for the week rather than all the trash included in the instance.

Comment by AllFatherYmer

Is it possible to pop the ore crates early to minimize phase 2? Can your ranged DoT up the crates to bring them down in health?

Comment by kaanna

So, does this mean that traditional BoP/Bubble/Ice Block/etc. cheese tactics are in play for the Acid Torrent, a la Iron Juggernaut mines? Or is this another mechanic that bypasses full immunities?

Comment by Phunshine

At 7 minutes Oregorger with begin casting Earthshaking Stomp as his enrage effect.

Comment by Robford

The Iron Flame Binders summon an elemental that does a continous raid wide aoe attack that can easily wipe a raid group. The summon cast should be interupted.

Comment by Shortzo

Acid torrent says it increases in damage with each cast; this is applied via a debuff to the first person hit, but it's not clear whether this affects the second stage damage (which is magical, not physical, and has a completely different damage range).
does anyone know?

An easy map for P2:
X=Wall
O=Ore crate spawn point
Breaking an ore crate allows Oregorger to eat ore. P2 ends when Oregorger eats 10 piles of ore. If an exposed ore pile is not consumed during this P2, it can still be consumed by Oregorger in the next P2.

O

Oregorger's rolling path:
When Oregorger hits the wall at ┫┻┣┳ squares it stops for 2 seconds to decide whether to turn left or right (it can never go back), and stay for another 2 seconds before it starts rolling. Some says it will always go to the direction with the most ore piles, but I have not confirmed it yet.

How to position:(edited)Stand on edges of squares and move between squares to avoid the hit.
1: If the boss is at the turning point near you then move there.
2: If the boss is not near you then you are always safe there.
3: Move around.

Whyzzim, that looks great in theory, but in practice, having just been dead for an extensive part of 2 attempts and having stealthed all over the map, the locations you have marked '3' are actually impassable. The map looks like:\n\n\n2\n\n\n\n\n

No offense - I wish as much as anyone that these really were safe areas.

You can use evasion if you ever find yourself in his path.

Comment by Jovio

As a thought for the tanks: The guide does not say this straight out, but could mention that the tanks should switch places when the taunting is done. It says:

When not tanking Oregorger, stand between the boss and the ranged group

and

The current off-tank should stand between the boss and the ranged players, and soak the Acid Torrent projectile.

It should be clear for everyone but it apparently is not.
