Oregorger

1.1. Normal and Heroic Difficulty

This guide covers both the Normal and Heroic versions of the encounter, as far as mechanics and general strategy is concerned. The only difference between these two modes is found in the tuning, with Heroic being more difficult.

When we speak of extreme situations (such as the difficulty of a soft enrage timer, or damage from a certain source being too high to survive), we mostly refer to Heroic mode.
1.2. Enrage Timer

We do not currently know what the hard enrage timer for this encounter is. There do not seem to be any soft enrage mechanics in the fight.
2. Summing Things Up

In this section, we will very briefly summarise what the players belonging to each of the three roles have to do during this fight. This is by no means meant to provide sufficient information to master the encounter, and it is only supposed to give you a very rough idea of what to watch out for.
2.1. Tanks

Perform a tank switch on the boss for each Acid Torrent cast. The tank currently tanking Oregorger must make sure that they are the closest player to the boss. When Acid Torrent is cast, consider using a damage-reduction cooldown.

2.2. Healers

During Phase One
Make sure that the tank who is being hit by Acid Torrent has some damage mitigation cooldown active, or otherwise be prepared for high raid-wide damage.
Heal the raid-wide damage from Acid Torrent, as well as occasional damage from Retched Blackrock, Explosive Shard, and Blackrock Barrage.
During Phase Two, heal the regular, increasing raid-wide damage, and make sure not to lose line of sight to other raid members.

2.3. DPS

During Phase One, DPS Oregorger.
During Phase Two, DPS and quickly kill Ore Crates.

2.4. Everyone

During Phase One
Interrupt as many casts of Blackrock Barrage as possible.
Avoid the Retched Blackrock void zones (ranged) and the Explosive Shards (melee).
During Phase Two
Avoid being hit by Oregorger.
Do not lose line of sight to the healers.

3. Overview of the Fight

The encounter against Oregorger is a single target, two-phase fight. Oregorger has a Mana resource, which determines when the phase changes occur.

He begins with full Mana, in Phase One, and each one of his abilities costs some Mana.
When he runs out of Mana, he enters Phase Two, during which he rolls around the floor of the room, collecting Blackrock Ore to refill his Mana.

When Oregorger has refilled his Mana, he goes back into Phase One, and so on until the end of the fight. Throughout Phase Two, raid members will have to destroy crates containing Blackrock Ore in order to ensure that Oregorger has enough ore to collect and refill his Mana pool.

4. A Note on Surroundings

You engage Oregorger in a rather large room, which is shaped much like a maze. Large rocks are scattered all over the floor, creating a network of corridors, and blocking line of sight.

During Phase One, as we will see, the layout of the room does not play an important role at all, but during Phase Two, it is very important. In this second phase, the boss will regularly roll through these corridors at great speed, and your raid members will have to avoid the boss as much as possible.
5. Phase One

Phase One lasts until Oregorger runs out of Mana, at which point he enters Phase Two. Most of Oregorger's abilities cost Mana, but, as we will see, there is one interruptible ability that only consumes Oregorger's Mana if the cast is successful.
5.1. Abilities

Acid Maw is a stacking Nature damage DoT that Oregorger applies to his tank. This ability requires a tank switch.
Acid Torrent is an ability that Oregorger uses regularly throughout Phase One. He deals a massive amount of Physical damage to the closest player to him, and he also deals raid-wide Nature damage. The amount of raid-wide Nature damage is, by default, very high, but it is reduced by the total damage mitigation of the closest player (the player who was hit by the Physical damage). The closest player will also be debuffed to take increased damage from Acid Torrent for 20 seconds.
Retched Blackrock is a damaging void zone that Oregorger regularly places at the location of random raid members (mostly ranged players). These void zones deal Nature damage, and they persist for a relatively long time.
Explosive Shard is an ability that Oregorger uses regularly throughout Phase One. He throws an explosive shard at the location of a random raid member (he seems to prefer melee players), which deals a high amount of Physical damage to any players in a small radius, knocking them back. 3 seconds after this, the shard explodes, dealing a high amount of Fire damage to any players around it, also stunning them.
Blackrock Barrage is an interruptible spell that Oregorger often casts throughout Phase One. It deals a high amount of raid-wide Physical damage. Every successful cast of this ability consumes some of Oregorger's Mana, but interrupted casts do not.

5.2. Strategy

The strategy for Phase One is, generally speaking, to interrupt as many casts of Blackrock Barrage as possible, while dealing with the rest of Oregorger's abilities. Doing so will prolong the amount of time the boss spends in Phase One (and reduces raid damage taken), which is arguably easier than Phase Two.

In the sub-sections that follow, we will go into detail about each of the tasks that the raid has to perform.
5.2.1. Tank Duties

There are two abilities that concern the tanks, namely Acid Maw and Acid Torrent. Acid Maw is easily handled through a simple tank switch, and as you handle Acid Torrent, this will happen on its own.

Acid Torrent, however, requires more explanation. This ability does not target Oregorger's tank, but rather the player closest to the boss. However, to make things easier, it is best if the tank currently tanking the boss moves in to be closest. When this ability is cast, the tank will suffer a massive amount of Physical damage (but because tanks have a lot of Armor, the damage finally taken will not be very great), and the raid then takes a very high amount of Nature damage. The important factor here is that the damage the raid takes is reduced by the total amount of damage reduction that the tank had active when he was hit by the Physical damage.

As a result, whenever Acid Torrent is being cast, the raid should make an effort to increase the damage mitigation on the tank. This can be done either through use of the tank's own cooldowns and abilities, or through the use of external damage reduction cooldowns.

Another component of Acid Torrent is that the affected tank will also take greatly increased damage from subsequent Acid Torrent casts within 20 seconds, which naturally means that the tanks should perform a tank switch to handle this debuff. Performing a tank switch for each Acid Torrent will solve the problem, and it will also deal with the Acid Maw debuff in the process.
5.2.2. Positioning and Movement

Your ranged raid members should stack together some distance away from the boss, while your melee players should be loosely spread out around the boss.

The ranged group will have to consistently move out of the Retched Blackrock void zones that the boss will throw at them. It is important that these void zones be placed as close to each other as possible, in order to conserve space (which is needed greatly, especially during Phase Two). As such, the ranged group should always be stacked together at the edge of the existing void zones, so that the void zones can even overlap.

On the Beta, having all ranged raid members in one single group was not a strict requirement, since the frequency of Retched Blackrock void zones was very high. As such, it was possible to have ranged players spread out in two groups, or even have them loosely spread out individually, but we still advise stacking into a single group.

Melee players will have to keep a constant eye out for casts of Explosive Shard, and when a shard is dropped, they need to make sure not to be in its close proximity when it detonates (3 seconds after landing). Moreover, melee players must make sure not to be closer to the boss than the tanks (as doing so could cause them to be hit by the Physical damage portion of Acid Torrent).
5.2.3. Blackrock Barrage

Interrupting as many casts as possible of Blackrock Barrage is very important. Depending on your raid size and composition, you may not be able to interrupt every cast, but you should still try. Each cast that you fail to interrupt will cause an amount of raid damage, and, more importantly, will reduce the amount of time that Oregorger spends in Phase One.
5.2.4. Healing Concerns

Throughout this phase, healers will have to mostly watch out for the raid (and tank) damage caused by Acid Torrent. For this purpose, using external damage reduction cooldowns on the tank who will be affected by Acid Torrent is an important part of the fight.

There will be additional raid damage caused by players who do not immediately move out of Retched Blackrock void zones, as well as both avoidable and unavoidable raid damage caused by Explosive Shard, but these damage sources should not require extraordinary amounts of healing.
6. Phase Two

Phase Two begins as soon as Oregorger runs out of Mana. The boss can no longer be tanked (and he does not melee anymore), and instead he simply rolls around through the room at high speed. As he does so, he collects any blackrock ore that he comes in contact with, and the phase ends when Oregorger has collected enough ore to refill his Mana.

The ore is located in a number of Ore Crates that spawn at the start of each Phase Two, which are scattered around the room. Attacking and killing these completely harmless and stationary crates reveals the blackrock ore that Oregorger can then collect.

When Oregorger reaches full Mana, Phase One restarts.
6.1. Abilities

Rolling Fury causes Oregorger to roll around the floor, dealing a very high amount of Physical damage to any players he comes in contact with, knocking them down.
Earthshaking Collision causes Oregorger to deal a small amount of raid-wide Nature damage each time he comes to the end of one of his rolls.
Hunger Drive is a stacking buff that increases the damage that Oregorger's Earthshaking Collision deals by 5% per stack.

6.2. Strategy

Throughout this phase, your raid will regularly take damage from Earthshaking Collision. This damage will ramp up as the boss gains more and more stacks of Hunger Drive, so it is in the raid's best interests to end the phase as quickly as possible. For this reason, DPS players should destroy as many Ore Crates as possible, as quickly as possible.

Throughout the phase, avoiding Oregorger as he rolls around is of paramount importance. Doing so is not very easy, however, because the pattern in which Oregorger rolls through the maze is very difficult to predict. There has been much speculation on the topic of Oregorger's pattern, but as far as we can tell no consensus has been reached. The only thing you can rely on is that the path that the boss took to reach a certain point is safe, since he will never roll back the way he came.

Players should be mindful of their positioning, since it is easy to lose line of sight to the healers while running around and trying to kill Ore Crates. The healers should be spread out throughout the room so that they can reach most raid members easily.
7. When to Use Heroism/Bloodlust/Time Warp

We recommend using Heroism Icon Heroism/Bloodlust Icon Bloodlust/Time Warp Icon Time Warp at the start of the encounter, since this is when all players will have their DPS cooldowns available, and especially because there are no other, more suitable moments during the encounter.
8. Learning the Fight

Your raid's success or failure in this encounter will depend on your efficiency during Phase Two. If many players get hit by Oregorger's rolling during Phase Two, or if the raid fails to destroy enough Ore Crates in time (before the raid damage overwhelms the healers), then this phase will lead to deaths. Therefore, it is important to stress proper efficiency in Phase Two, and to ensure that players are always mindful of their position as far as line of sight to the healers is concerned.

During Phase One, the area in which you have the most room for improvement (or for mistakes) is interrupting Blackrock Barrage, so setting up an efficient interrupt rotation is very important.

Re: Oregorger


Boss encounters are a series of mini-games that, when mastered, will result in a kill.

Re: Oregorger

It's a very interesting fight and phase 2 is just a matter of killing of the right crates, walk the correct route and keep an eye on the boss.

Re: Oregorger

Very doable just need to be aware of where you are all the time, not hard to side step him as needed.

Re: Oregorger

As phase 1 is very straight forward and the challenge is handling phase 2 correctly, I made a few images showing movement and Oregorger's impact points.

As soon as phase 1 starts, the entire raid will follow Oregorger and waits till he chooses a direction as seen in image 1.

http://bossblueprint.com/savedImages/wow/blackrock-foundry/oregorger-the-devourer/dgNi:M9RU.jpg

Green = Ore Crate.
Cross + Square = Possible Directions.

When he chooses to go Cross, we need to be careful on which Ore Crate to destroy first. Oregorger will always favors a direction where ore is exposed for him to eat.

Because Oregorger will always chooses a path that will take him to next possible ore to eat, we'll need to destroy the crate at Skull first.
Note that the whole raid stays clear of his impact point. Also melee dps is likely to stay back and hold dps, because of the risk of being run over and be stunned or die.

Shown in image 2 is crate kill order when Oregorger choose Cross

http://bossblueprint.com/savedImages/wow/blackrock-foundry/oregorger-the-devourer/EQBc1teXZ.jpg
[*]Note that when Oregorger chooses to go to Square the kill order of the crates at Star isn't important

Next the Triangle Crates need to be destroyed and after that moving on to Circle

Now the raid will need to split up for the remaining 4 crates at Square and Diamond.
http://bossblueprint.com/savedImages/wow/blackrock-foundry/oregorger-the-devourer/zFBApwF1E.jpg
Moon will be the ideal position for the raid to wait while Oregorger eats the 4 remaining ores, however this will be depending on how fast we will be able to destroy the crates.

Important to know is that we control the path Oregorger will choose by destroying crates and exposing ore. Destroying a crate to soon could alter his path and could cause him to roll over the raid.

HOLY WATCH THIS - https://www.youtube.com/watch?v=DDGEPPf … qwqiyuvraJ

Hey look.. they follow Oregorger (well to an extend).. Didn't I suggest that? tongue

Anyway, it seems that we simply start out wrong. So start the boss on the outer right should make things easier indeed. People will still need to be aware of their surroundings though.
