3. Overview of the Fight↑top

The encounter against Tsulong is a two-phase fight. The two phases,called the Night Phase and the Day Phase, alternate throughoutthe encounter, on a fixed timer.

• During the Night Phase, Tsulong is hostile, and your raid must DPS him,while dealing with several of his abilities.
• During the Day Phase, Tsulong is friendly, and your raid must heal him (muchlike the Valithria Dreamwalker encounter in Icecrown Citadel), while protectinghim from various types of adds.

In order to defeat Tsulong, you must either bring him to zero health duringa Night Phase, or to full health during a Day Phase. Tsulong's health isreversed each time a phase change occurs, so that the amount of health thatis missing from Tsulong's health in the Night Phase becomes the amount ofhealth he has during the Day Phase. For example, if you DPS Tsulong down to80% health in the first Night Phase, when he enters the Day Phase, he willhave 20% health. If you then heal a further 20% of his health during thisphase (bringing him up to 40% health), he will have 60% health whenentering the Night Phase.

When first engaged, Tsulong will be in the Night Phase, and every twominutes after that he will switch between phases. He has an energy barthat slowly fills up over time, and a phase transition occurs each time the baris full. However, since the boss always gains energy at the same rate, anddoes not use his energy for anything, this has no implications for your raidand it is merely a means to tell how close the next transition is.

Tsulong will always enrage a few seconds after the end of the second DayPhase.

4. Night Phase↑top

The Night Phase is the first phase that Tsulong will be in. The phase lastsfor exactly 120 seconds, after which time he enters the Day Phase.

4.1. Abilities

During the Night Phase, Tsulong makes regular use of the followingabilities.

• Shadow Breath is a frontal cone breath attack that deals ahigh amount of Shadow damage and applies a stacking debuff to the affectedtargets, which increases Shadow damage taken by 100% for 30 seconds, perstack. This ability forces the use of two tanks.
• Dread Shadows is a stacking debuff that Tsulong applies to all raidmembers every 2 seconds. Each application deals a moderate amount of Shadowdamage, and increases the damage that the players take from Dread Shadows by10%.
  • To counter-act the Dread Shadows debuff, Tsulong regularly creates a Sunbeam at a random location within the inner circle marked on the floor.This is a large beam of light that removes the Dread Shadows debuff from anyplayer who moves into it. However, each second that a player stays in theSunbeam, its radius becomes smaller, until it eventually disappears.
• Nightmares is a spell that Tsulong regularly casts at the locationof a random player. It deals a large amount of Shadow damage to all playerswithin 8 yards of the point of impact, and also fears them for 3 seconds. Thefear effect can be dispelled. This ability does not appear to target meleeplayers.

4.2. Strategy

We will begin by summarising the strategy for this phase, before going intomore details.

• Have Tsulong tanked facing away from the raid, and perform atank-switch for every one of Tsulong's Shadow Breaths. Make surethat the tank currently not tanking Tsulong is not in front of him.
• Have the ranged DPS and healers spread out at least 8 yards apart, tominimise the damage and fears caused by Nightmares. Dispel playersaffected by the fears immediately.
• Make sure that everyone regularly resets their stacks of Dread Shadows by walking into the Sunbeams.
• DPS Tsulong.

4.2.1. Positioning

As we mentioned, Tsulong should always be facing away from the restof the raid, and no other players except the tank that is currently tankinghim should be in front of the boss. This is important, since the boss' Shadow Breath is extremely damaging.

It seems that the locations where Sunbeams spawn are more or lessrandom (although it could also be that it always spawns in the same placerelative to where the boss is facing, and it appears random since the bossoften turns to face players when casting Nightmares on them), it maysometimes prove to be in front of Tsulong. In this case, the tanks must bequick to turn the boss (and everyone else must adjust their positionsaccordingly).

The rest of the raid should spread out in a semi-circle around the boss,making sure that everyone is at least 8 yards away from other players. Thiswill help minimise the damage from Nightmares greatly.

Everyone (including the player originally targeted) can avoid being hitby Nightmares, as the animation on the ground precedes the damaging effect byabout 3 seconds, giving players ample time to move out of it. In fact, thespell works more or less like shadow crash spells.

4.2.2. Tank Switching

Tanks can realistically only survive Tsulong's Shadow Breath with no stacks of the debuff applied by the breathitself. This means that a tank switch should take place after every breathattack cast by the boss.

Even though we have mentioned it before, we will reiterate that it isvery important that the tank currently not tanking Tsulong does not stand infront of him.

4.2.3. Resetting Dread Shadows

A crucial aspect of this phase is making sure that everyone resets their Dread Shadows debuff. Ideally, everyone should reset their debuffsbefore they exceed 15 or so stacks.

When resetting the debuff by running into the Sunbeam, you mustbe mindful of two things.

• You should only be in the Sunbeam for a second, moving in and out quickly.This will allow the Sunbeam to persist for longer, increasing the number ofplayers who can use it.
• You should make sure not to have too many players running to reset theirdebuff at the same time, since they all risk being hit by Nightmares ifthey are in close proximity to one another.

You will have to assign an order for players to reset their debuffs, andkeep in mind that a Sunbeam will not last long enough to allow the entireraid to reset their debuff. It may also be possible (and sometimespreferable, maybe) to simply ensure that players have a means of trackingeveryone's stacks of Dread Shadows on their raid frames, and that theyjust use common sense and on-the-fly assignments for resetting theirstacks. In any case, this is something that pertains to the organization ofthe raid.

Finally, tanks must also remember to reset their debuffs whenever they arenot tanking Tsulong.

5. Day Phase↑top

2 minutes after the start of the Night Phase, the Day Phase will begin.This phase lats for exactly 2 minutes, after which time the Night Phase willonce again begin.

5.1. Abilities

During the Day Phase, Tsulong is friendly to your raid.

• Sun Breath is a frontal cone breath attack that Tsulong regularlycasts. It deals a very high amount of damage to any adds it hits. If it hitsany raid members, it buffs them with Bathed in Light.
  • Bathed in Light instantly restores 25% of the player's maximum mana,and increases their healing done by 500% for 6-seconds.

Three types of adds are present during this phase.

• Embodied Terrors are large adds spawned by Tsulong. They placea dispellable debuff called Terrorize on random raid members and onTsulong himself.
  • When cast on players, Terrorize damages the player for 20% of theircurrent health each second for 10 seconds.
  • When cast on Tsulong, Terrorizedamages him for 2% of his total health every 2 seconds for 10 seconds.
• Fright Spawns are small adds that are created when an Embodied Terroris killed. Each Embodied Terror produces 5 Fright Spawns upon death. These smalladds often cast Fright in a cone in front of them, dealing a high amountof damage and fearing all affected players.
• Untable Shas are adds that spawn around the room, and move towardsTsulong. If they reach him, they deal a very high amount of damage to himthrough Instability, and they disappear. While traveling towardsTsulong, they also cast Unstable Bolt at a random raid member, dealing ahigh amount of damage, but losing 15% of their own health in the process.

Keep in mind that if there are any adds alive when the Day Phase ends, theywill not despawn when the Night Phase begins. Your raid will have to killthem. Any Unstable Shas that reach the boss during the Night Phase will healhim instead of damaging him.

5.2. Strategy

The strategy for this phase can also be summarised rather simply.

• Have your healers always stand in front of Tsulong, so as to benefit from Bathed in Light as often as possible.
• Heal Tsulong.
• Make sure that the Embodied Terrors and the Fright Spawns aretanked in front of Tsulong whenever possible, so that he damages them with hisbreath.
• Make sure that the Fright Spawns are always facing away from the raid.

5.2.1. Healing Tsulong and Other Healing Concerns

Your raid's main goal during this is phase is not only to survive, but alsoto heal Tsulong as much as possible. As we have explained before, anyhealing that you do to the boss during this phase is the same as damage doneto him during the Night Phase, and contributes to your success in theencounter.

Firstly, healers should always position themselves in front of Tsulong,so as to benefit from the Bathed in Light buff granted by his breathattack. We will remind you that the breath attack does not damage raid membersduring this phase, and only damages adds. Also, Tsulong often turns around,meaning that he will not always face in the same direction, and the healersmust be quick to adapt to the boss' new position.

It is important to note that Lay on Hands does not work to heal theboss. The cooldown of the ability will be triggered, Tsulong will gain Forbearance, but no healing will be done.

Also, it is very beneficial for healers to make use of the increasedhealing received by targets affected by Guardian Spirit and Life Cocoon.

In addition to healing Tsulong, the healers will have to keep the rest ofthe raid alive. There are several sources of damage to note.

• Tank damage from the melee attacks of the Embodied Terrors andFright Spawns, as well as very high tank damage from the frontal coneattacks of the Fright Spawns.
• Damage on random raid members caused by the Terrorize debuff, aswell as by casts of Unstable Bolt.

Healers must be prepared to dispel the following three effects during thisphase:

• the Terrorize debuff from Tsulong;
• the Terrorize debuff from random raid members;
• the fear effect caused by Fright, from tanks or any other raidmembers hit by this cone attack.

5.2.2. Dealing with the Adds

Your tanks and DPS players' only concern during this phase is to kill theadds. This is extremely important, not only for your raid's survival, but alsobecause it reduces the damage that Tsulong takes.

Whenever an Embodied Terror spawns, the tank should pick it up andmove it in front of Tsulong. Your raid should kill it, ideally with a fewseconds to spare before Tsulong uses his breath attack. If done correctly,this will cause all the Fight Spawns to be instantly killed by the breathattack. If your raid is too slow in killing the Embodied Terror, Tsulong'sbreath will miss the adds, and your raid will have to kill them, which isgoing to be quite disruptive due to their fears. The boss mod timers forTsulong's breath are accurate, and the timing of the Embodied Terror spawnsis fixed, meaning that you can train your raid's DPS to kill the EmbodiedTerrors in time for each wave of Fright Spawns to be killed by the breath.

Untable Sha adds are the top priority, since they must be killedbefore they reach Tsulong, or else they deal a massive amount of damage tohim. These adds cannot be tanked, but you can stun, slow, and knock them back.Death Knights can use Death Grip and Gorefiend's Grasp against themas well.

Only one tank is needed for this phase, since there is a long time betweenEmbodied Terror spawns.

6. One-Tanking the Fight↑top

A user on our forums has put forth the possibility of using a single tankfor this fight. While this is easy and requires no explanation as far as theDay Phase is concerned, it is a bit more complicated during the NightPhase.

What you must do is have a DPS player taunt Tsulong off of the maintank right before a Shadow Breath, and then have your tank tauntthe boss back. This will allow the tank to drop their stacks of the debuffapplied by Shadow Breath, and continue tanking.

There are several issues to keep in mind.

• A tank will, at best, be able to survive two consecutive Shadow Breaths.For surviving the second one, they will need to use a major defensivecooldown.
• The debuff applied by Shadow Breaths increases damage taken, and thisincludes the damage from Dread Shadows stacks.
• Tanks will have to reset their stacks of Dread Shadows while tankingTsulong, which will involve turning him to the Sunbeam. If the tank makessure not to do this right as a Shadow Breath is being cast, there should beno issues.

The DPS player who taunts Tsulong must be able to survive his Shadow Breath,and potentially also a melee attack. Whoever does this should use a majordefensive cooldown, preferably one that reduces magic damage taken.

This strategy may only be viable in 10-man Normal mode. Additionally, whileit will increase your raid's DPS (by allowing you to bring an additional DPSplayer), it may also cause quite a few complications. We only really recommendit if you are unable to bring two tanks to your raid for other reasons.

7. When to Use Heroism/Bloodlust/Time Warp↑top

We recommend using Heroism/ Bloodlust/ Time Warp during aNight Phase. This is because there are fewer distractions for your raidin this phase than in the Day Phases, and we suspect that it is moreefficient, in terms of progressing on defeating Tsulong, to DPS him ratherthan to heal him.

8. Learning the Fight↑top

Your raid will have to learn how to properly handle the mechanics in bothof Tsulong's phases. Fortunately, since the phase transition happenspurely based on time, it is possible just focus on getting through the NightPhase (at the cost of lower raid DPS) simply to experience the Day Phase.

During the Night Phase, the most difficult aspect by far is proper usage of Sunbeams, and properly resetting Dread Shadows. This may take somepractice, but once this aspect is mastered, the remaining abilities in thisphase should be easy to handle.

During the Day Phase, your raid will have to become accustomed to standingin the way of Tsulong's breath. Additionally, efficient killing of theFright Spawns will probably prove to make the difference between successand failure in this phase. It is imperative that all players focus onkilling these adds as soon as they spawn, to make the learning of the fighteasier.

We do not know what the enrage timer of the fight is, nor what the finaltuning of the damage values of the abilities is like, but we expect that thefight will provide a considerable challenge in these regards.

9. Achievement: Who's Got Two Green Thumbs↑top

The Who's Got Two Green Thumbs? achievement is part of the Glory of the Pandaria Raider meta achievement. The achievement requires thatyou defeat Tsulong while keeping the Enchanted Plant alive forthe entire encounter.

The Enchanted Plant is an NPC located on the right of the stairs which youdescent to get to Tsulong after entering the raid instance. The plant doesnothing for the entire fight, and it has a relatively low health pool. Duringthe Night Phase, the plant takes steady damage from Dread Shadows, whichwill require your raid to throw a few moderate heals its way. During the DayPhase, the plant does not take any damage.

Neither the boss, nor any of the adds directly target or attack the plant,so overall it requires minimal healing. Even hybrid classes such as BalanceDruids or Elemental Shamans can easily keep the plant alive by healing it a fewtimes during the fight.

10. Heroic Mode↑top

The Heroic mode of Tsulong presents two significant changes from Normalmode, although they do not greatly complicate the fight, nor do theyalter your raid's strategy significantly.

10.1. Differences From Normal Mode

In addition to Tsulong and the adds having increased health and dealingincreased damage, there are two changes in Heroic mode, one in each phase.

During the Night Phase, Tsulong will regularly spawn adds calledThe Dark of Night. These adds do not do anything except walk directlyto the Sunbeam. If an add reaches the Sunbeam, it is instantly despawns. Theseadds can be slowed and knocked back, and they do not have very much health.

During the Day Phase, Tsulong will regularly spawn a beam of light calledThe Light of Day. Each beam can be clicked by a player, and this grants thatplayer a 6-second buff that provides greatly increased healing and manaregeneration. The healing increase is diminished over the 6-second period,while the mana regeneration is progressively increased over the 6-secondperiod. Clicking a beam causes it to disappear. The buff granted by these beamsdoes not stack with the one granted by standing in Tsulong's breath during thisphase.

10.2. Strategy

In general, your strategy will remain unchanged. For each phase, you willwant to make minor modifications to deal with the Heroic-only mechanics, andwe will go over these below.

10.2.1. Night Phase

During the Night Phase, your raid must focus on killingThe Dark of Night adds before they can reach the Sunbeam. Since they canbe knocked back and slowed, your raid shouldn't really have trouble withthis.

That said, sometimes, you are better off letting the adds reach the Sunbeam,ignoring them and focusing your DPS on Tsulong (for example, when the beam isjust about to expire on its own anyway). Additionally, sometimes the existingSunbeam will expire naturally while the adds are up, and the new one willspawn directly on top of an add. If this happens, there is nothing you can doand you will have to endure the increased raid-damage caused by not being ableto reset your stacks. This is when healing cooldowns should be used to keep theraid alive until a new Sunbeam appears.

10.2.2. Day Phase

During the Day Phase, you will have to make optimal use of the Light of Daybeams. These should be clicked by your healers, and they should use the buffto heal Tsulong more. It is ideal to click the beam when you have a cooldownor proc active, so you should have your healers communicating so that no beamsare used without cooldowns and procs.

Additionally, as we said, the buff does not stack with the buff you receivefrom Tsulong's breath during this phase, so make sure that you do not click abeam right before or right after Tsulong's breath.
