Enter Izshrash'Khar: Stratum of the Protectors at 711, 255, 693 on Sothshae in Vesspyr Isles.
NOTE: There is a 365% CC Debuff (Corruption) so you will need VERY good pre-ToV armor or at least the quested ToV armor/jewelry. Also, even the trash mobs have millions of HP's (at least on Beta on 11/02/13)
NOTE: Damage numbers listed below for the named mobs were obtained on Beta on 11/02/13 so may be subject to change!
Be careful when you kill the trash because sometimes when they die, they do a big knock back
Kill A Mystic Contruct
Fight him where he stands since he will pull you to him if you move away
As the fight progresses, colored energy streams will flow into him. One gives him stoneskin and another heals him. In order to do enough DPS to take him down, I had to have my Inquisitor merc fight with my SK (I usually have him just stand and heal).
I'm not sure what the correct strategy is concerning him. Clicking on the pillars to activate the symbols may have helped
each energy panel when stood on will give the player a buff they are as follows: (south) 100 DPS, (east) 50% healing received, (north) 50% potency, (west) Autoattack damage multiplier 0.500, (center) spell&melee damage by 1.0.
Click on the pillar at 76, 1756, -76 to activate the 3rd symbol
Continue clockwise up the ramps to the Reliquary of the Emperor
Once you start combat, make your way back to the elevator and fight him at -16, 1477, 5 (just outside the elevator room) with your back wedged in a corner
During the fight, he will occasionally split into fragments (5 or 6) - burn them down with AOE's
Also, during the fight, Shazzak will teleport himself about 1/2 way between the elevator and the ramp leading up to his platform. When he does this, run into the elevator building to avoid the falling rocks. When he is done, he will let out a blast that would have knocked you off the island had you not been in the elevator building. After the blast, run back to your corner and wait for Shazzak to come to you.
Rinse and repeat
One last thing, don't click on the elevator button to take him back up (to avoid knockback problems) because if you fight him on the elevator, you will fall through it to your death....Snakes in a Plane - yes.....Snakes in an Elevator - no
Click on the pillar at -117, 1484, -68 to take you back to the entrance
