Xiaoyin Xu will be the 5th Raid Boss in the Wonder Works Factory. Players will have encountered him as a mini-boss in Act II in the “Over the Rainbow” fight where he will escape at 33% health.
Cornered, Xiaoyin Xu is attempting to access the control room for the IR-Tx Mechanical when he is engaged by the raid. The Mechanical is behind a Titanic Energy Grid, essentially inaccessible until the security protocol is bypassed.
The raid will be assisted by Taran Zhu and his three lieutenants: Jiao, Quan, and Taoshi. Each member will deploy a rune on a player corresponding to one of the Aspects. These players must use their ability to dispel the debuff put on players to avoid a wipe.
Phase 1: Add killed, Xiaoyin at 75%
Adds will alternate casts of Chains of the Golden Fel. This is an interruptible cast. If successful, will link 3 players and mark them with a debuff. They will need to be dispel/cleansed with the Aspects ability before Xiaoyin casts:
Empowered Soul Gate: Xiaoyin Xu will mark a target with a debuff causing ticking shadow damage for 13 seconds. At the end of the debuff, Xiaoyin Xu will randomly teleport to a marked player and cause them to explode with shadow damage, injuring players within 13 yards. If there are multiple players with the Chains Debuff, he will teleport to one and the other marked players will send out shadow damage to 40 yards (probably blanketing the room).
Empowered Soul Gate can be neutralized by a player with a holy mark of the Aspect to cleanse it from them. In LFR, this would be handled by the NPCs. Normal/Heroic would require the specific mark tied to each Aspect. In Mythic, this must be done in the correct order as displayed above on the Energy Grid (e.g.:Tiger, Crane, Ox, Dragon). Every time the buffs are refreshed, the order would change; dispelling the buffs in the incorrect order causes the Empowered Soul Gate to explode prematurely.
In non LFR each of the four Shado Pan have a limited amount of resources/hp. As the fight goes on, Xiaoyin’s assistant Tshin-tao will summon fleshling adds to kill them. They have a limited number of heals/hp/chi. Should too many Shado Pan fall, it is a wipe. The limited number of casts/amount of hp and adds attacking will be a dps check for phase 1.
In Mythic, Taran Zhu will protect the other three but be attacked by an additional add that will suppress (silence) his ability to heal. When that is cast, another group of adds will attack one of the other lieutenants, so the raid will have to keep Taran and one other protected.
If Xiaoyin reaches 75% health before the add is killed, he will begin to heal the add and himself.
The goal of Phase 1 is to manage the Soul Gate mechanic and kill the add Tshin-tao.
Phase 2: The Warlock – Xiaoyin to 10%
Xiaoyin will use the martial forms of the Golden Fel and directly engage the raid. Golden Fel causes damage and provide a slight stacking HoTs to Xiaoyin. If he is able to cast too many, he will begin to heal beyond the raid’s ability to damage him.
Chi Bolt (Chaos Bolt): A surge of golden chi energy strikes the target in a cone in front of him and applies an immediate flat heal plus 0.5 stacks of Golden Energy.
Golden Lightning: a channeled spell adding .01 stacks of Golden energy per second (channel lasts 5 seconds). Interruptible.
Summon Golden Fel Sha: Summons a group a fel-empowered sha – every hit adds 0.1 stacks of Golden Energy. When the add dies, it explodes and leaves a void zone for the rest of the fight. Soft enrage mechanic.
Life Nova: Xiaoyin engulfs himself in flames clearing all stacks of Golden Fel. The power of the fel gives back some of the life it takes in damage to others. Each stack restores 1% health per 8 seconds for 8 seconds.Stacks to 25%. This is a retreat mechanic which requires the active tank to soak/mitigate while the raid disperses.
Phase 3: The Wangliang
At 10% Xiaoyin enrages, shedding all pretense of his Pandaren form and revealing the Wangliang demon form. He will begin to Siphon Life to attempt to heal himself marking a player with a DoT/HoT. He will alternate casting a heal for himself and Sha’s of Corruption.
Sha’s of Corruption. He will spew four smaller Golden sha from his mouth that pursue marked targets. Sha’s reaching their target explode (leaving void zones) and channel a conduit of healing back to Xiaoyin Xu.
Upon reaching 0 percent Xiaoyin Xu damages the Energy Grid and permits access to the IR-Tx Battle module.
