Boss Icon - Lei Shi


This guide is intended to provide a comprehensive description of the encounter with Lei Shi in Terrace of Endless Spring. It is targeted at anyone who desires to understand the fight mechanics.

This guide is updated for World of Warcraft WoD 6.1.2.

Lei Shi is the third boss in the Terrace of Endless Spring raid instance. This is a straightforward, single-phase fight, which does not pose any significant positional challenges.

The difficulty of the fight comes mostly from the strict enrage timer, which is made harder to beat due to the fact that Lei Shi is often unattackable.

Overview of the Fight

The encounter against Lei Shi is a single-phase fight. The fight requires two tanks, who must alternate tanking the boss. As the fight goes on, Lei Shi's casting speed progressively increases, resulting in more and more tank damage.

When Lei Shi reaches 80%, 60%, 40%, and 20% health, she summons several adds, and goes immune until at least one add has been killed.

Additionally, she sometimes disappears and must be damaged through AoE attacks in order to return.

Finally, a few times during the fight, Lei Shi will channel a sort of wind that pushes all players away from her and damages them. Players will have to move against the current and damage Lei Shi in order for the effect to break.



Lei Shi does not perform melee attacks. Instead, she constantly spams Spray Icon Spray at her current target. This deals a large amount of Frost damage to that player and all players within 2.5 yards, and adds a stacking debuff to all affected players, which increases Frost damage taken by 16% per stack, for 10 seconds.

Afraid Icon Afraid is a buff that Lei Shi gains a stack of each time she loses 10% of her maximum health. For each stack, Lei Shi's casting speed is increased by 8% for the remainder of the encounter. This results in much faster (and thus more frequent) casts of Spray.

When Lei Shi reaches 80%, 60, 40%, and 20% health, she shields herself (becoming immune to all damage), and spawns several Elemental adds called Animated Protectors. These adds have normal threat tables, and have no abilities. Their melee attacks are extremely damaging, but they are susceptible to crowd-control. Lei Shi will remain shielded until one of the Animated Protectors is killed, at which point her shield will vanish, and all remaining Animated Protectors will despawn. For the first two Protect casts (at 80% and 60% health), Lei Shi summons 3 adds, while on the final two Protect casts, she summons 4.

Finally, Lei Shi has two more abilities that she casts, although the timing of them was rather erratic on the Beta.

  • Hide Icon Hide is an ability that Lei Shi sometimes casts. She goes invisible, and cannot be targeted. Lei Shi will continue to cast Spray (at random raid members, this time, rather than at the tank) while in this state. The only way to force Lei Shi to become visible again is to deal a certain amount of damage to her. While she is not visible, if a player is close enough to Lei Shi's location, they can see certain indicators of her whereabouts (clouds, sparks, etc.). Players then have to spam AoE abilities in this location.
  • Get Away! Icon Get Away! is an ability that Lei Shi sometimes casts. She teleports to the center of the platform, and begins channeling a spell for 30 seconds. This spell pushes all players away from Lei Shi, dealing a large amount of Shadow damage to them every second. Players who run towards Lei Shi (so, against the current) only take half the damage. Lei Shi can be forced to stop this channel prematurely by dealing 4% of her maximum health in damage to her.


The strategy for defeating Lei Shi can be summarised as follows.

  • Have the two tanks alternate tanking her, in order for the debuff applied by Spray Icon Spray not to stack too high.
  • When Lei Shi casts Hide Icon Hide, distribute your DPS players evenly on the platform, so that you can quickly find Lei Shi and break her out of invisibility.
  • When Lei Shi casts Get Away! Icon Get Away!, run in towards her and deal as much damage as you can through instant casts, in order to force her to stop the channel.
  • When Lei Shi casts Protect Icon Protect, focus down one of the Animated Protectors. When one Protector is killed, the others will simply despawn. The other Protectors should be crowd-controlled or tanked.


Your raid should form a triangle, where one corner is your main tank, one is your off-tank, and the other is the rest of your raid, with Lei Shi located in the center. This will allow the two tanks to taunt Lei Shi off of each other without risking having both of them affected by the same Spray Icon Spray. The raid can stack safely together, since there are no abilities (other than Spray) that deal damage in an area.


Dealing with Protect

One of the more delicate parts of the encounter is when Lei Shi casts Protect Icon Protect. Even while Lei Shi is shielded, she will continue to spam Spray Icon Spray at her main target. Additionally, the Animated Protectors deal very high melee damage.

You will want to have a tank switch right before the protectors reach the raid (you have a few seconds of warning thanks to their spawning animation), in order to allow as much time as possible to kill the Animated Protectors. This is because, once your off-tank picks them up, it will be very difficult to perform a tank-switch between your tanks, and the damage of tanking both Lei Shi and the adds at the same time is too great for a single tank.

Therefore, your aim is to have the Protectors killed before a new tank switch is required.

We remind you that only one Protector needs to be killed for Lei Shi's immunity to break, and that when one Protector dies, the others immediately despawn. Therefore, there is absolutely no benefit in AoEing the Protectors (they do not share health pools), and you should focus on killing one of them.

We encourage you to crowd-control the Animated Protectors you are not killing, since this will reduce the damage your tank takes, and it will make this part of the fight easier.


Dealing with Get Away

Get Away! Icon Get Away! is another difficult mechanic to deal with. The damage that the wind current deals to your raid is very high if you are standing still. Therefore, all raid members must be moving forward, towards Lei Shi. However, while moving forward, you cannot cast any abilities with a cast time (unless you are using class-specific abilities that allow you to do so, such as Spiritwalker's Grace Icon Spiritwalker's Grace for Shamans, or Kil'jaeden's Cunning for Warlocks), which greatly reduces your raid's DPS and healing.

Your raid should use cooldowns at this time, both defensive (Devotion Aura Icon Devotion Aura and Rallying Cry are excellent) and offensive, in order to survive more easily.

Your goal is to damage Lei Shi for 4% of her maximum health as quickly as possible, in order to break the effect. We suspect that DoT classes and classes that can do a lot of damage while moving (such as Hunters) will be at an advantage here, but it remains to be seen how much damage Get Away! Icon Get Away! will do, and how much health Lei Shi has.


When to Use Heroism/Bloodlust/Time Warp

We recommend using Heroism Icon Heroism/Bloodlust Icon Bloodlust/Time Warp Icon Time Warp towards the end of the fight, particularly when Lei Shi is below 20% health. This is the part of the fight when Lei Shi deals the most damage, so you will want to kill her as quickly as possible.

Ideally, you should use Heroism/Bloodlust/Time Warp immediately after dealing with a Get Away! Icon Get Away!, Hide Icon Hide, or Protect Icon Protect phase, in order to minimise the downtime you have while the cooldown is active.


Learning the Fight

The Lei Shi fight is not a complicated one, and the boss has a strikingly low number of abilities that your raid must deal with.

The first thing to master is the tank switch that must be performed regularly. This is a little more difficult than usual tank switches due to the fact that the debuff applied to the main tank by Spray Icon Spray can splash to the off-tank if they are too near, and also due to the high frequency of Spray casts. Therefore, properly executing the triangle formation we described in the guide is important.

The next big test for your raid will be the ability to survive the damage of Get Away! Icon Get Away!, and to deal the required amount of damage to Lei Shi to break the effect. This will most likely take some practice at first, and you should not hesitate to use any available cooldowns to get through this phase (you can even save your cooldowns specifically for it).

Finally, the Protect Icon Protect "phases" should be handled with care, as the melee damage from the Animated Protectors is high and can surprise your raid.

Overall, however, there is very little synergy between Lei Shi's abilities, so the tasks that your raid needs to get familiar with can be considered and learned independently of each other.


Achievement: Face Clutchers

The Face Clutchers Icon Face Clutchers achievement is part of the Glory of the Pandaria Raider Icon Glory of the Pandaria Raider meta achievement. The achievement requires all of your raid members to be affected by a debuff called Parasitic Clutch Icon Parasitic Clutch when you defeat Lei Shi. The Parasitic Clutch debuff is obtained by attacking certain adds called Parasitoid Sha, which are located in the waters around Lei Shi's platform.

These adds just swim around in the water and do not do anything unless attacked. When attacked, each add will fixate on the player that attacked it, applying the Parasitic Clutch debuff, which is a DoT that deals a small amount of Shadow damage to that player every 3 seconds. There is a limited number of adds in the water, but once they attach themselves to players, new adds soon spawn in the water.

Once each player is fixated upon by an add (which essentially latches onto your character), all you need to do is complete the encounter as you normally would. There is added difficulty due to the increased raid damage from the adds, and this is something you simply need to survive.


Heroic Mode

The Heroic mode for this fight presents an innovative new ability that actually renders the fight considerably more difficult. For most players, the fight will appear to be largely unchanged, but a few select raid members will have some crucial tasks to perform.


Differences From Normal Mode

Lei Shi and the Animated Protectors both have increased health, and deal increased damage. The Animated Protectors in particular will one-shot any non-tanks that they hit, and even tanks will take extreme damage.

The new mechanic is something called Scary Fog Icon Scary Fog. This is a stacking debuff that Lei Shi constantly applies to all players who are not within around 10 yards of her hitbox. The debuff lasts 35 seconds, and has two effects.

  • It causes the affected player to take a small amount of Shadow damage every 3 second, per stack.
  • It causes all targets (friendly or hostile) around the affected player to take 10% increased damage, per stack. We are not sure about the radius of the effect, but it appears to be about 10 yards.


The strategy of Heroic mode is pretty simple. Your raid's goal is to spend as much of the fight as possible with Lei Shi being debuffed by the Scary Fog Icon Scary Fog (so, by having someone affected by Scary Fog in range of her). All the while, you want to make sure that no one else in your raid is affected by the debuff.

You will assign several players to stand outside of Lei Shi's range, stacking Scary Fog on themselves, and moving in next to Lei Shi in an alternating fashion to cause her to take increased damage.


Stacking Scary Fog

As we said, Scary Fog Icon Scary Fog stacks on players who are essentially outside of Lei Shi's melee range. The goal of your raid is to have two players (as well as possibly a third as a back-up, as we will discuss below) standing outside of Lei Shi's range, and having the Scary Fog stacking on them. These players should be well away from the rest of the raid and the tanks, and they should also be out of range of each other (so that they do not cause one another to take increased damage).

After the start of the fight, when these players reach a reasonable number of stacks (between 5 and 9 stacks is a good number, but this depends on how many stacks of the DoT the healers can heal through on the affect players), one of them should move into Lei Shi's melee range, where they will remain until their Scary Fog drops off. At this point, the other player who is stacking Scary Fog will move in, while the first player goes back out and re-starts stacking Scary Fog on themselves.

You can also have three players stacking Scary Fog on themselves, to ensure that you never get to a situation where no one has Scary Fog, but this may not be necessary.



Your raid should be stacked very close being Lei Shi, either to her right or to her left. This will allow the player with Scary Fog to move in on Lei Shi on the other side from where the raid is, and remain there to debuff the boss without touching the raid.

The tanks still need to taunt off of each other to deal with the debuff that Lei Shi stacks on them, and they cannot stand in the same position. These are positioning constraints that you will need to iron out on your first attempts, but it is possible to have the two tanks, the raid, and the Scary Fog player all in Lei Shi's range without any conflicts.


Handing Protects

Protect Icon Protect is much more dangerous on Heroic mode, since the adds deal a lot more damage than in Normal mode. To ensure that the designated add dies quickly, you should have someone with Scary Fog be in the add's range. In 25-man (or in 10-man, if you are using 3 tanks), you can have the add tank stand outside of Lei Shi's range before a Protect is cast so that they stack Scary Fog on themselves.


Handling Get Away!

Get Away! Icon Get Away! is much more damaging in Heroic mode, so it is imperative that Lei Shi is debuffed with Scary Fog Icon Scary Fog while she is casting this, so that Get Away! is broken as quickly as possible. The player who is debuffing Lei Shi with Scary Fog has to be careful not to accidentally debuff any other players around her (and these players must also be careful of the same thing), because taking increased damage during Get Away! will very quickly lead to deaths.


Handling Hide

Hide Icon Hide must be broken as quickly as possible, since Lei Shi does not stack Scary Fog Icon Scary Fog during this time, which can cause the stacks to drop off from the Scary Fog players if it goes on for too long. Many abilities can be used to find Lei Shi quickly at the start of a hide, Mind Sear being a prominent example.
