General

Get to this zone off the Sokokar post at Omen's Call.

Its a fairly linear zone, with no tricks to layout or mazes. There are levers that must be clicked to open doors to further areas, often the door opened is a room or 2 back.

One of the harder zones in the expansion - orange mobs further in.

Bosses

Sanedrac the Lost

First boss is visible from the zone in. He becomes active after the levers in the rooms to either side are simultaneously activated (need to clear to them). The only real trick he has is reflects spells - bard green debuffs especially can be nasty. You can however safely use Combat Arts. He also has a nasty trauma dot that if not cured from the respective group member will completely power drain that person.

Once past him take the lift down to the next level, where there is a quest update near the spider that jumps you at the end of the left corridor

Selgrak the Monster

Down in the main hall, Selgrak summons friends from the pods around the room. They are the main problem as they have an aoe stifle.

To defeat him clear the entire room and the hallway to the north of Selgrak. Once the hallway is clear have the main tank stand on the stairs and pull Selgrak. The healers should be in the doorway between the hallway and Selgraks orginal room and your secondary tank or DPS tank shall intercept the adds when they come in at 85%, 65%, 45% 25% and are immune to mez and root. If the adds get close to the hallway then a massive damage AOE will occur. Its best to keep the adds on the main square of Selgrak's room while keeping the ability of the healers to heal both parties.

Sannik the Unfinished

Since Game Update 51 the "thousand pound stone" has been removed from this mob

As he randomly teleports members to one of 3 sides of his room you have to cure Noxious before you move from the little cove where you were teleported. If you fail to cure yourself and try to move you will AOE the entire group. If you run of of potions you can just range fight from the cove until the detrimental has expired.

A good tank spot is wedged in at -108, -52, -306 Copy , with the group opposite, so his knockback won't kick all over the room.

If you can chain stunning him would be another method to defeat his teleporting and kick backs.

Guard Captain Kelkrin

Pretty straightforward. The chest key mob, an Atrebite keybearer, is in his room. The shard chest itself is at -209, -72, -158 Copy . The Captain will Power Drain, Stifle, and has an AE.

Ka'El Ka'Vrish

Very nasty AOE which will deal an intense amount of damage, killing most classes instantly. The key to this fight is to range it while located at the corners near the tables to stop from being thrown back during his room wide kick backs. His additional, yet weaker AOE will still hit you but as long as you cure elemental and heal through it you'll be fine. Utilize your long range bows and any other 35 meter spells to hit him and it will take about 5 minutes. If you happen to get knocked off the platform up top you can run back up the stairs just be aware of the glowing globes that are near him as they will kill you if you get close.

An alternate way of defeating him is to time his immense-damage AoE, then have melee joust in and out accordingly.
