WoW MoP Classic Terrace Of Endless Spring Raid Tsulong Boss Guide

Posted: Sep 10, 2025 Views: 34

Everyone, today we're taking a look at Tsulong, the second boss encountered in WoW MoP Classic Terrace of Endless Spring raid.

As a major cloud serpent, Tsulong is one of the early bosses in this raid, and players must defeat him before they can proceed and face other powerful enemies, such as Lei Shi and Sha of Fear. Beyond that, defeating this boss will drop Mists of Pandaria Classic gold and raid gear, which are crucial for facilitating smoother encounters later.

Tsulong Mechanics

Tsulong encounter occurs in two phases, following a day and night cycle.

The first phase is the night phase. Tsulong starts with full health, requiring DPS, as he needs to resist the corruption of Sha of Fear. He will then briefly awaken from a nightmare and plead with the raid to restore him to full health so he can better fight Sha of Fear.

However, whatever his health was during the night phase, it will be reversed during the day phase. This means that if he's at 75% health at the end of the first night phase, he'll only be at 25% at the start of the next day.

Our goal is to either restore him to 100% health during the day or reduce his health to zero during the night.

Either way, you'll help him break the corrupting influence of Sha of Fear and continue his progress up the mountain.

The team composition for this encounter is a bit unique, as you need to bring as many healers as possible, with 7-8 being ideal. However, if you overload your healers, you might quickly lose the boss's second phase because of insufficient DPS.

Night Phase

Depending on Tsulong boss fight's mechanics, we've divided this guide into two parts.

First, there's the Night Phase. While in a pulsing state, Tsulong is enveloped in darkness. The corruption of Sha of Fear has consumed his senses, and we hope to lull him into consciousness and help him realize who he is.

This phase lasts two minutes, and our goal is to DPS him while taking heavy damage before the day phase arrives.

Dread Shadows

Every 2 seconds during the night phase, everyone in the raid will receive a stack of Dread Shadows, dealing approximately 45,000 Shadow damage and increasing Shadow damage taken by 10%.

While this isn't too bad early on, if too many stacks accumulate, the raid will suffer significant damage. Therefore, we want to purify them by entering Sunbeams.

Sunbeams

These Sunbeams are obtained with the help of the friendly Tsulong, hidden deep within Dragon Soul. We receive our first Sunbeam stack shortly after the start of the game. After that, new ones will spawn every 40-45 seconds.

Each time you enter a Sunbeam, absorbing sunlight reduces its size and power. Therefore, players should constantly enter a new Sunbeam, clear any Dread Shadow stacks, and then quickly exit, lest they absorb all the beams too quickly and force the raid to wait 45 seconds for the next one. Never do this.

So, the best strategy is to enter quickly soak up the sun, and then exit!

The Dark Of Night

To complicate matters slightly, The Dark of Night will appear at random locations and slowly move toward the beam. If it reaches the beam, it will absorb all of its energy, temporarily blinding you.

These Dark of Night spawns are random, but you can assign stun mitigation classes or Death Knights to control them to ensure you have enough time to cleave them. Please note that The Dark of Night should never be near a Sunbeam under any circumstances.

In addition, Tsulong's Shadow Breath can stack with a 100% damage debuff for 30 seconds. Therefore, your tank should taunt swap as much as possible during this effect and set a cooldown for each Shadow Breath. The combination of Shadow Breath and Dread Shadows means you'll take a significant amount of damage.

Nightmares

The final event of this phase: Every 15 seconds, Tsulong will drop three large purple circles of Nightmares on the ground. These take two seconds to trigger after becoming visible, so be sure to stay away from them.

If you're hit, you'll take massive damage, and combined with the damage dealt by Dread Shadows, even if you only get hit once, survival will be even more difficult. So spread out, avoid them, and stay alive.

Day Phase

Okay, now let's move on to the Day Phase.

Tsulong finally awakens from his nightmare, looks around, realizes he's been injured, and pleads with you to heal him so he can have the strength to resist Sha of Fear's corruption once and for all. Healers, this is your time to shine!

To do this, you'll need to utilize some of Tsulong's abilities to help heal him.

Sun Breath

First, every 30 seconds, Tsulong will cast Sun Breath, a 3-second spell that releases a massive burst of healing energy in front of him, dealing significant damage to Sha's attacks. It also grants Bathed in Light buff to players struck by it, restoring 25% of your mana and granting you a 6-second buff that increases your healing by 500%.

500% is a lot, but the players we typically assign to exploit this effect aren't the ones doing the bulk of the healing. Those utilizing The Light of Day are the ones doing the bulk of Tsulong's healing.

The Light Of Day

These small beams now randomly pop up in a small radius. If you right-click them, they grant you a healing buff called The Light of Day, increasing your healing by 1,500%. Yes, that's three times the healing of Sun Breath.

These beams now refresh every 10 seconds, with the first appearing at the transition from Night to Day.

Also, only three The Light of Day beams can be active at any given time. If a fourth appears, the first will disappear, so keep that in mind.

Unstable Sha

Your goal during the Day phase is to protect Tsulong's healing from interruptions so you can finish the fight faster.

Unfortunately, enemies seeking to interrupt your healing can spawn in various corners of the room.

These enemies primarily fall into two types. The first is Unstable Sha. These monsters spawn randomly and move toward the boss. If they come into contact with the boss, they explode, dealing approximately 5 million damage, which is very bad, especially since we're trying to keep Tsulong at full health.

Therefore, we split our DPS into four groups and spread them around the room, but not too far from Tsulong, as we still want them to be within healing range. We need to kill all the Unstable Sha monsters as soon as they spawn and do everything we can to prevent them from getting close to the boss.

Embodied Terror

Another enemy is aimed at tanks: Embodied Terror. These powerful enemies have nearly 18 million health in Heroic mode and should be killed quickly, as they randomly apply the Terrorize effect to both the player and Tsulong himself.

Terrorize effect deals Shadow damage equal to 50% of the player's current health every 1 second, and also deals Shadow damage equal to 5% of Tsulong's current health every 2 seconds. Therefore, when this ability is activated, it's important to dispel Tsulong first, then the player.

Since Tsulong's Sun Breath actually deals significant damage to Sha's minions, if you drag an Embodied Terror into him, he'll attack them with his breath, dealing nearly 5 million damage and stunning them for 8 seconds.

However, we don't want to use this ability on Embodied Terror monsters because once they die, five smaller monsters called Fright Spawns will spawn. These will run around and scare nearby players. So, the goal here is to stun these Embodied Terrors before the breath is released, which should instantly kill them.

Tsulong has four Breaths in total: one at 30 seconds, one at 60 seconds, one at 90 seconds, and a final one at 2 minutes. After his final Breath, he returns to Night phase.

Note: Before his final Breath, healers and DPS players only need to thoroughly cleanse Tsulong, and the boss is done!

That concludes our introduction to Tsulong boss in Terrace of Endless Spring raid. Honestly, this boss's dynamic phases are unlike any other enemies we've encountered before, but once you get the hang of it, defeating it isn't difficult!
