Deepstone Fractal
Treasure Hunters discovered a ancient Dwarven Vault of Deepstone
In Deepstone you get to experience a dark secret ruins filled with puzzles, hidden treasure, enemies and of course, spiders! Deepstone is dark, and ominous but at least you get to explore with Kay and Torin...
Entrance
At the start of Deepstone you are up on some cliffs with, you just need to jump down a few levels, there is some Bats in the way - you can either kill them or just skip them and go down towards the Vibrant Crystal. Take the small hallway, and you will be in a room that lets you go either East or West, and you can choose which one to take down first.
East Path - Windy Bridge / Spider Room
The eastern path will take you to a bunch of spider nests, and small spiders, clear these out and progress to the bridge. On the bridge there will be telegraphed AoE's that will push you off the bridge - you will be immediately pushed back up at the start of the bridge if this happens. The spiders nests will cause a slow effect called Sticky Web, that will make getting across more difficult, you will need to disable the trap to progress, to do this you need two players to stand on the two runes at the wide part of the bridge, once both are activated and glowing you can proceed.
In the next room you will be locked in, you have to kill two Elite Broodmother Spiders to spawn the Brood Queen Spider.
During the fight small adds will spawn to attack you, just maintain them so they dont overrun you, a few AoE's should kill multiples of them. Watch for the telegraphed cone attacks from the Brood Queen as well.
After the fight there will be a orb to interact with, doing so will take you back to the start, interact with the Vibrant Crystal while holding the orb
Achievement - Of Spiders and Sentinels
5 AP
In the Deepstone fractal, kill both the Brood Queen and Deepstone Sentinel within three minutes of each other
You are able to disable both traps from both sides before starting either fight to speed this up. You will have an achievement tracker in your buff bar while this is active
West Path - Electric Trap / Elemental Room
The trap section of the west side is significantly quicker, you just need two people to get past the moving electrified squares on the ground and stand on the two runestones at the end, this will disarm the path and allow the team to move into the Elemental Room.
In this room there will be one enemy, the Deepstone Sentinel. It will spawn Wind Spirits/Tornados every 20% health, these tornados do have a defiance bar but you can mostly ignore them and simply dodge. If you do get caught in one you will get lifted up your team mates will have to break the bar to get you out.
After killing the Sentinel you can touch the orb of light in the middle of the room to be taken back to the Vibrant Crystal, interact with it again
Central Room / Empty Abyss Room
Now that you have both of the orbs of light you need to get a go back to the Vibrant Crystal, using both orbs of light will grant a Special Action Key(SAK) to everyone - Light of Deldrimor
This special ability will serve a few purposes until the end of the Fractal, the first is to reveal and cause Light Vulnerability to corrupted foes, but also to reveal Hidden Treasure Chests. After getting this skill, head back to the central chamber and use it on the Shadow Minotaur to reveal it and damage it, kill him and al the other adds to progress. head north through a short tunnel to find the empty abyss room.
In this room there will be two runestones that the NPCs will stand on, as well as four orbs of light that you need to trigger with Light of Deldrimor - to do this you need to start on the east side of the room, and use the SAK to reveal the pathway.
Do this until you trigger all four Orbs which will let you progress to the next room - Spectral Flames will be spawning around the room trying to destroy tiles, they are easy to kill so just destroy them before they have to chance to destroy any tiles.
Achievement - Riches Unveiled
5 AP
Find All 10 Deepstone's Hidden Chest in One Run
To do this achievement you need to find all 10 Hidden Treasure Chests around the Fractal, you can reveal these using the Light of Deldrimor. See guide below for possible locations!
Chest locations are random, but you will see a small glimmer/sparkle in the location you need to use the skill
Elevator
Next you will be on a elevator taking you to the final room, there will be some NPC dialog, and you will have to fight some Shadow Imps, just use your SAK to increase your damage, kill them all to progress
North Chamber / Torin
In the final chamber Torin will rush ahead and be turned into The Voice, the final boss.
The fight will have tiles that fall away and can be brought back with the SAK, similar to the Abyss Room - The Voice will use Bombs/Aoe's that will break away the tiles during the fight.
If you fall you will be swept back up due to 5 stacks of Residual Updraft to protect you as long as you and your allies have been restoring the floor tiles.
80%/40% - When The Voice gets to 80% and 40% he will teleport across the room and get a barrier, he will also be casting a red beam on every party member that causes damage - get over to him and break his bar to end this phase
61%/21% - At 61% and 21% The Voice will become invulnerable to damage completely and Spectral Flames will be spawning around the room, destroy 10 of them to make The Voice vulnerable again, if too many reach him he will do a room wide AoE that does fairly big damage.
After defeating the voice make sure you run to the end to check for any Hidden Treasure Chests
