Prerequisites
Before fighting Emperor Ssraeshza, your raid will need to complete two tasks:
1) To enter the Emperors Chamber each character must perform the Key Quest.
2) Non-spell caster classes will need to obtain Bane Weapon’s in order to damage him (bane weapon guide coming soon)
Is Emperor Ssraeshza up? Two requirements must be met:
1) Emperor Ssraeshza initially spawns as untargetable, but he will be up on tracking as a low level mob. You’ll also see him sitting on his throne in an untargetable state.
2) Either Blood of Ssraeshza or Ssraeshzian Blood Golem must be up. Killing one of these two mobs triggers the event and makes Emperor Ssraeshza targetable. The difference between the two golems is that Blood of Ssraeshza drops loot while Ssraeshzian Blood Golem (a PH) does not. Unless someone attempts and fails to kill Emperor Ssraeshza, typically you’ll see Blood of Ssraeshza and Emperor Ssraeshza up together.
— The golem (PH) has somewhere between 12-24 hour respawn (with variance) and Emperor Ssraeshza has a 3 day respawn. This means if you fail to kill Emperor Ssraeshza you must wait up to a day for Ssraeshzian Blood Golem (PH golem) to respawn in order to attempt again. If you succeed and kill Emperor Ssraeshza then it will respawn in 3 days. Blood of Ssraeshza (loot version of golem) also has a 3 day respawn.
Fight Strategy
Upon first zoning into the chamber you’ll see a giant golem in the middle and 8 snakes surrounding it. The general strategy is to kill the golem and CC the snakes. Approx. 3-6 minutes after the golem dies Emperor Ssraeshza will spawn.
Snakes
Four of the snakes are mezzable and four must be offtanked. They are all aggro linked. The puller will get harmtouched so you can use DA to pull if necessary. Two of the non-mezzable snakes also proc a -75% heal debuff. It can be curse cured (9 counters). You will need to keep the snakes CC’s for the entire duration of the fight. If you kill the snakes they will simply respawn after 2-2.5 minutes. They hit for around 300-400 each.
Grziz the Tormentor – mezzable
Klazaz the Slayer – mezzable
Zlakas the Slayer – mezzable
Skzik the Tormentor – mezzable
Nilasz the Devourer – not mezzable — casts 75% heal debuff, also flurries
Heriz the Malignant – not mezzable
Yasiz the Devourer – not mezzable — casts 75% heal debuff, also flurries
Slakiz the Nalignant – not mezzable
Blood Golem
The golem hits for around 500-600 and has relatively low HP. It is slowable. It also will dispel the main tank. Kill the golem and wait (3-6 minutes, exact time not verified) for Emperor Ssraeshza to spawn while CC’ing the snakes. Enchanters can use the Spell: Rapture to avoid resists on snake mezzes.
Emperor Ssraeshza
Emperor Ssraeshza has a few abilities:
– Rampages (have a rampage tank pull)
– Procs a 95% deaggro/4000DD/slow/AC debuff on the main tank. Curse curable (36 counters)
– Casts spin stun on the main tank
– Hits for up to 950 depending on tank gear. Hits fast.
– Slowable but only by cold based slows
– Cannot be meleed by normal weapons. Must use Ssra bane weapons.
– Has a substantial amount of HP.
– Cold and Fire spells work best for casters
The key to this fight is slow and steady DPS, lots of heals/cures on the main tank, and keeping the snakes CC’d. Patience and coordination are key.
The raid can move into the front corner of either side of the room and not aggro and snakes, so engaging from there is helpful. Also the door at the entrance to his room is 1 way. Once you pass through you cannot go back.
Once Emperor Ssraeshza is dead finish off the snakes and have the raid move back into the corner so the snakes do not reaggro when they respawn. Upon death, there several A shissar wraith that spawn around the room. Each one drops a handful of 
Planes Rift. These are part of the Vex Thal Key.
