Underground Facility Fractal
Clear out the Dredge from this location to help stabilize the Fractal
This Fractal, similar to the Aquatic Ruins has a few paths that all end in the same room, but the paths will be random.
Starting Area
When you first start out you will be in a tunnel near a ramp covered with Dredge, the first think you will need to do is assign someone to go up the higher ramp and find the pressure plate.
When they are standing on it, a door will open to the next ramp, when at least one person has made it through the newly opened gate this player can regroup with the team
Another person will have to go up the newly discovered ramp on the right side of the bridge and find another pressure plate. Once standing on that a new room will open.
In the main control room there will be two pressure plates - you need two people to stand on these fairly quickly and have someone go interact with the newly opened control panel. The person interacting with the panel can not move, use skills, or be attacked or it will interrupt. Players standing on the plates can still use their skills though to help. The remaining two players not on a pressure plate and not interacting with the panel will need to pull and kite all of the enemies to prevent interruption.
Once this is done the enemies will run away and you can go through the newly opened door which will lead to one of two possible path ways
Split Pathway
Right Way - If you are going right this run you will be in the stealth/bomb section. In this room there will be a steam pipe that offers very long stealth and a pipe that is dropping bombs. There will be Dredge stealing the bombs as well once they drop.
The goal in this room is to get nine bombs to the pipe at the end of the hallway, to do this you need to avoid the traps and avoid the sentry detection, so get yourself stealthed, grab a bomb and move past the sentries without getting close to them - you will have 20 seconds to do so, drop the bomb in and go back to reset this process After getting nine in you will move to the mini boss room
Achievement - Subject 6 Deep-Sixer
5 AP
Use stealth to bomb the reinforced door without triggering any security turrets or contractors within the Underground Facility
Left Way - If you are going left you will be in a room with a box that you can interact with that gives Dredge Mining-Laser - this will replace your skill bar, a ramp leading being bombarded with AoE's and a big circle doorway, there will be Dredge that spawn here.
What you need to do is grab the Dredge Mining-Laser and bring it up to the circle door way and use Skill 1 on it. If you get hit by the AoE's on the ramp or use any dodge abilities it will change the skill and make it explode on you, if this happens, drop the gun and go back for another one.
Once the door reaches 0% you will move onto the mini boss room.
Rabsovich
The mini boss will be Rabsovich, he is fairly simple, just stack on him and DPS, he should die quickly. He will have adds spawn around him, pull them in and AoE them down as usual. once he is dead the cart will thrust forward and break the door
Legendary Dredge Powersuit / Legendary Rampaging Ice Elemental
The last boss room will have two different bosses you can potentially face off against, the Legendary Dredge Powersuit or the Legendary Rampaging Ice Elemental, they will both have the same mechanics for the most part. You wont be able to do real damage to the boss until you drop the lava on them from the Molten Ore bucket at one of the four corners of the room.
Molten Ore - The main mechanic of both these fights is the Molten Ore - you need to kite the boss around the room, most groups start with the NW one (Directly to the players left when walking in) but the order doesn't matter. The player doing the kiting will be fixated, notified with a purple marker above their head - this will change randomly.
You need to kite the boss under the molten bucket, on top of the scorch marks on the ground, one player will either need to run up the ramp or teleport up and pull the lever while the boss is standing on those marks, this will apply Superheated which will last 30 seconds and cause the boss to take significantly increased damage
Once the boss has been hit with that you need to DPS as quick as possible while also watching the timer on Superheated. Once the debuff starts to lower in time, move to the next one around the room that you have coordinated with the team. Repeat this until the boss has been defeated.
Healing Phase - If you see the boss stop moving and kneel or plant itself you will need to interrupt this by using a stun or knock down skill
After a few Molten Buckets you should be done and the chest will appear where the boss was originally.
