The Stone Guard

 

 

This guide is intended to provide a comprehensive description of the encounter with The Stone Guard in Mogu'shan Vaults. It is targeted to anyone who desires to understand the fight mechanics.

This guide is updated for World of Warcraft MoP 5.0.5.

The Stone Guard is the first encounter in the Mogu'shan Vaults raid instance. Its relatively low difficulty is a testament to its status as an entry-level encounter.

On normal mode, the fight will mostly test your raid's ability to switch targets and to react to simple mechanics, all while maintaining reasonable amounts of healing.

Overview of the Fight

This encounter consists in a single phase that repeats until you defeat the 4 Quilen Guardians that make up The Stone Guard:

• Amethyst Guardian;
• Cobalt Guardian;
• Jade Guardian;
• Jasper Guardian.

The Guardians have a shared health pool, and each Guardian has its own individual energy bar. The Guardians gain energy when they are close to other Guardians, and when a Guardian reaches maximum energy, it unleashes a very damaging, raid-wide attack. Each Guardian has its own version of this maximum-energy attack; these attacks are called Overloads. Fortunately, at any given time, one of the Guardians is also providing protection to the raid from its own maximum-energy attack, in the form of a 90% damage reduction from that attack.

Therefore, the main objective of the encounter is to control the order in which the Guardian's energy bars fill up, by moving them close to, and away from other Guardians, depending on which Guardian is applying the debuff.

A few seconds after a Guardian uses its maximum-energy attack, a new Guardian will start applying its debuff, and it is this Guardian that you must get to maximum energy.

This cycle continues until you defeat the Guardians.

Additionally, the Guardians have a few damaging abilities, which we will also detail.

Finally, note that in 10-man and LFR, only 3 of the 4 Guardians are active (which of the 4 are active is chosen at random each lockout), while in 25-man all 4 are always active.

Energy Generation

In their normal state, the Guardians are affected by Solid Stone, which causes them to take 90% reduced damage, and not generate any energy. This buff is removed if a Guardian is within 12 yards of another Guardian.

When they are within 12 yards of each other, the Guardians generate energy at a rate of approximately 1.7 per second, regardless of what actions your raid takes. As we mentioned above, it will be your goal throughout the fight to often move Guardians together, and then apart, in order to control their energy generation.

Abilities

Besides Solid Stone, mentioned above, all the Guardians have an ability called Rend Flesh. Rend Flesh is a bleed effect that each Guardian applies on its tank. It lasts 15 seconds and deals a moderate amount of physical damage. This bleed effect does not stack. Overall, it is not problematic.

In addition to this, each Guardian has its own set of 3 abilities. While these are different for each Guardian, they can easily be categorised as follows (Amethyst abilities are only used by the Amethyst Guardian, and so on).

• Amethyst Pool, Cobalt Mine, Jade Shards, Jasper Chains are damaging abilities. Throughout the fight, the Guardians will regularly attempt to damage one or more raid members with these abilities.
• Amethyst Petrification, Cobalt Petrification, Jade Petrification and Jasper Petrification are the Petrification abilities that one (and only one) of the Guardians will use per cycle. These abilities apply a stacking debuff to the raid (it takes the form of a resource bar that fills up to 100). If the Guardian manages to stack this debuff fully, the raid will become paralyzed. The Petrification is broken by the Guardian's Overload (explained below). Petrification also greatly reduces the damage done by the respective Guardian's Overload. For example, Amethyst Petrification only reduces the damage done by Amethyst Overload, but not the damage done by Cobalt Overload.
• Amethyst Overload, Cobalt Overload, Jade Overload and Jasper Overload are the Overload abilties that the Guardians will use when they reach maximum energy. An Overload deals damage to the raid, stops the Guardian from casting petrification, and removes the Petrification debuff from the raid.

Damaging Abilities

• Amethyst Pool is cast by the Amethyst Guardian. It is a void zone, placed at a random raid member's location, that inflicts Shadow damage ever second to everyone inside it. It lasts 1 minute and 20 seconds, and it is cast roughly once every 5-10 seconds.
• Cobalt Mine is cast by the Cobalt Guardian. It is a cobalt shard launched at a random raid member's location. After 3 seconds, the shard becomes active, and any player who comes within 7 yards of it causes it to detonate, dealing Arcane damage to all allies within 7 yards, also rooting them for 6 seconds. This is ability is cast every 10 seconds.
• Jade Shards is cast by the Jade Guardian. It is a raid-wide nuke, dealing a small amount of Nature damage to all players. This spell is cast every 10 seconds.
• Jasper Chains is cast by the Jasper Guardian. It links two random raid members together (indicated graphically by chains). If the two players are more than 10 yards apart from one another, the chains deal Fire damage to them every second. The damage is increased by 15% (10% in LFR) for each second that the two players are more than 10 yards apart, and being more than 10 yards apart for 15 seconds removes the chains. Note that this effect is cumulative, meaning that you do not need to be apart for 15 continuous seconds; for each second that you are apart you get a stack of an otherwise harmless debuff, and at 15 stacks the chains are broken. The spell is cast roughly every 10 seconds.

Petrification

Petrification is an ability that Guardians possess, but only one of the Guardians can cast its Petrification ability at one time. It is a stacking debuff (although it appears on players' screen as a distinct resource bar) that is applied on the entire raid. If the debuff reaches maximum, it paralyzes its targets.

• Petrification has a maximum capacity of 100, and it takes around 80 seconds for it to reach maximum capacity.
• Petrification is cast for the first time 5 seconds into the fight, and again 5 seconds after each Petrification ends.
• A random Guardian is selected to cast Petrification each time, and the same Guardian cannot cast petrification twice in a row. There seems to be a tendency for the Guardian with the lowest energy to be chosen to petrify the raid, but we cannot confirm this.
• While Petrification is stacking on players, they take 90% reduced damage from the school of damage belonging to the respective Guardian
  • Amethyst Petrification: Shadow;
  • Cobalt Petrification: Arcane;
  • Jade Petrification: Nature;
  • Jasper Petrification: Fire.
• Reaching maximum Petrification can only be prevented by the Guardian's Overload (see below), and not by another Guardian's Overload. For example, Cobalt Overload does not remove Amethyst Petrification.
• Reaching maximum Petrification causes all players to become unable to move or act. They continue to take damage, meaning that it always leads to a wipe.

It is important to differentiate between the two Petrification states:

• The first represents the fact that one of the Guardians is applying the debuff to the raid, reducing damage taken from their school of damage.
• The second represents Petrification at maximum capacity, when the raid is stunned. This second effect must always be avoided.

Overload

Overload is the final ability of the Guardians. Overload is only cast when the Guardian reaches 100 energy. It deals a large amount of damage of the Guardian's school, and stops Petrification.

• Amethyst Guardian casts Amethyst Overload.
• Cobalt Guardian casts Cobalt Overload.
• Jade Guardian casts Jade Overload.
• Jasper Guardian casts Jasper Overload.

5 seconds after Overload breaks a Petrification, a new Petrification begins. An Overload from a Guardian other than the one who is currently petrifying the raid will have no effect whatsoever on the Petrification.

Strategy

The strategy for defeating The Stone Guard revolves around two concepts:

• Each Guardian who casts Petrification must overload (reach 100 energy) before he finishes petrifying.
• Do not allow Overloads to take place without the respective Guardian's Petrification being active. For example, Amethyst Overload should not happen without the raid being protected by Amethyst Petrification.

This means that the Guardians will have to often be moved close and away from one another, in such a way that the petrifying Guardian is always within 12 yards of another Guardian (so that he gains energy, in order to overload). At the same time, you should minimise the amount of energy that non-petrifying Guardians get, by rotating which of them is in close proximity of the petrifying Guardian.

We detail this in a dedicated section.

Positioning

In 10-man and LFR, you should have two locations for tanking the Guardians. In one location, your off-tank should keep a Guardian that is not casting petrification, while in the other, your main tank should keep the petrifying Guardian together with the lowest-energy Guardian.

The Guardians only have to be more than 12 yards apart in order not to gain energy, so it is advised not to have the two tanking locations too far apart.

The rest of your raid members should stand close together near the center of the room. There are two important positioning challenges for your raid members.

 

• Raid members must be quick to move out of Amethyst Pool whenever it spawns underneath them.
• Raid members must be quick to move away from Cobalt Mines when they are placed next to them.

Finally, Jasper Chains also requires that the affected raid members move, which can cause some interactions with the abilities mentioned above, although it should not be problematic.

None of the other abilities of the Guardians pose any positional problems.

Taunting and Positioning the Guardians

The energy generation of the Guardians is determined entirely by their positioning, so it is up to the tanks to make sure that the strategy of the encounter is executed properly. We believe that it is optimal, for several reasons, for the tanks to remain stationary in the pre-assigned tanking locations, and to simply perform taunt switches between them, whenever a Guardian must be moved.

Tanks must expect to taunt Guardians roughly every 20 seconds, which is neither problematic in terms of the cooldown of taunt, nor in terms of the diminishing returns of taunt.

The tanking locations we provided in the previous section are approximate, of course, since tanks will sometimes have to move, due to the location of Amethyst Pools or other damaging abilities.

Guardian Energy Management

The principle for managing the energy of Guardians optimally can best be summarised as always have the petrifying Guardian next to the Guardian with the lowest amount of energy.

The best strategy is to rotate the Guardians, always moving the petrifying Guardian next to the lowest non-petrifying Guardian. The ideal time to move the Guardians is every 25 energy in 25-man, and every 50 energy in 10-man and LFR.

Naturally, when you find yourself in a situation where the energy of the non-petrifying Guardian you are currently using is less than or equal to the energy of the other non-petrifying Guardian(s), you should maintain the status-quo, for convenience. This is because you will need to choose a non-petrifying Guardian to gain more energy than the other(s) anyway, so it might as well be the one you are currently next to.

Dealing with Mechanics

The encounter checks if your raid members are able to react accordingly to a number of abilities, while maintaining the required amounts of DPS, HPS, and threat. In this section, we will go through each ability and the way in which it should be dealt with.

Amethyst Pool

Amethyst Pool is simply avoided by stepping out of it. As the fight goes on, the floor of the room will become increasingly covered by the pools, but finding safe spots should not be an issue.

This ability can interact with Cobalt Mine, which can root players in place. We will detail this in the section below.

Cobalt Mine

Cobalt Mine should be avoided by moving away from the crystal shard. However, since the floor of the room can become quite crowded, your raid may opt to detonate some mines on purpose (while making sure that no one except the detonating player is within 7 yards of the crystal).

When the Mine is detonated, it damages and roots all players within 7 yards of it. The root effect lasts for 6 seconds, and is dispellable. The root effect can interact negatively with Amethyst Pools, preventing players from moving out of the pool. In this case, healers should be quick to dispel and heal the affected players.

The idea time to purposefully detonate Cobalt Mines is during Cobalt Petrification, since the 90% damage reduction renders them practically harmless. However, if the mines are becoming problematic and a Cobalt Petrification is not forthcoming, you will have to detonate them and simply heal the damage.

Jasper Chains

Jasper Chains links two random players together. In order for the chains to disappear, the players must stand 10 yards away from each other for 15 seconds. However, standing at this distance causes the chains to deal damage to the two players, so this is not always the best option.

There is no other way to get rid of the chains.

We advise your raid to implement a "buddy system" for handling the Jasper Chains. In short, the system relies on not breaking the Jasper Chains that link two players, and having the two players stand close to each other for the rest of the fight. This is made possible by the fact that there is a limit to how many chains can be active at one time (3 in 10-man; unknown yet in 25-man), meaning that your raid will only have to control a few buddy pairs.

The system we propose works as follows. Every time two players are linked by chains, they become each other's buddy. The two players should always stand next to each other (within 10 yards), and move together throughout the remainder of the fight.

Since it is problematic if a healer and a melee DPS are linked together, undesirable links can be broken while there is a Jasper Petrification going on (since the damage the chains deal will be vastly reduced). Your raid can continue to do this until favourable links are formed (melee DPS with melee DPS, healer with ranged DPS).

Alternatively, it is possible for your raid to pre-assign buddies, and break all chains (during Jasper Petrification) that do not correspond to these buddies. This is easier to organize beforehand, but it may result in too much confusion during the encounter.

As we mentioned earlier in the guide, the linked players do not need to spend 15 consecutive seconds apart - this effect is cumulative, so they can simply move in and out of range of each other and still eventually break the chains.

Sources of Damage

Healers will have to contend with the following sources of damage:

• Steady tank damage from melee attacks and the Rend Flesh bleed.
• Regular raid-wide damage from Jade Shards.
• Random avoidable single or multiple target damage to players from Cobalt Mine.
• Avoidable damage from players standing in the void zones created by Amethyst Pool.
• Varying damage from Jasper Chains, depending on the strategy your raid is using.
• High raid-wide damage from overloads, each time a Guardian reaches 100 energy (roughly 200,000 damage after reductions).

A situation of particular interest occurs when a player is rooted by Cobalt Mine while inside a void zone from Amethyst Pool. In this case, that player must quickly be dispelled so that he can move out.

Cleaving and Multi-Dotting

Since two Guardians will always be tanked together, classes with cleave effects (Arms Warriors, Combat Rogues) or DoTs (Warlocks, Shadow Priests, Balance Druids) can boost their (and the raid's) DPS greatly by taking advantage of the situation.

These techniques are highly advised, especially since the Guardians have a shared health pool.

When to Use Heroism/Bloodlust/Time Warp

The fight does not have different phases, nor does its difficulty change as it goes on. Therefore, you should use Heroism/ Bloodlust/ Time Warp at the start of the fight, to maximise the benefit of players' potions and initial cooldowns.

Learning the Fight

As the encounter is stable in difficulty, and no new phases are unlocked by reaching a certain stage of the fight, the best way for your raid to learn the fight is to ensure that everyone understands fully how to handle each of the mechanics individually.

• Players must move out of Amethyst Pool;
• Players must move away from Cobalt Mine;

In addition to this, all that your raid must know is what the basic mechanics of the fight are (Guardian energy generation, petrification and overloads).

Achievement: Must Love Dogs

The Must Love Dogs achievement is part of the Glory of the Pandaria Raider meta achievement. It is a very simple achievement for your raid. It simply requires that each one of your raid members is accompanied by a canine non-combat pet (companion) when defeating The Stone Guard.

We currently know of the following viable canine companions (based on a comment on Wowhead):

• Perky Pug (easily obtained as a reward for completing roughly 25 heroic dungeon through the Dungeon Finder Tool);
• Core Hound Pup (obtained by anyone who attaches a Blizzard Authenticator to their account);
• Curious Wolvar Pup (a reward from the Children's Week world event);
• Worg Carrier (a drop from Quartermaster Zigris in Blackrock Spire);
• Fox Kit (small drop chance from Baradin Foxes in Tol Barad Peninsula).
