In order to enter Dzemael Darkhold, accept the quest from Carrilaut near the Observatorium. This dungeon can also be unlocked by accepting the quest Shadows Uncast from your Grand Company HQ if you are at least a Sergeant First Class. This is required to rank up past a certain point, so I recommend picking it up as well.
Near the start of Dzemael Darkhold, you will encounter an All-seeing Eye which will ignore you and fly through the tunnel. It will stop occasionally to cast Eyes on Me, dealing ~1000 damage in a pink blast around it. In the hallway, you will also find crystals with a purple ground effect around them. This ground effect will greatly lower the damage Eyes on Me deals, so try to fight the trash in these circles.
You will also find blue glowing Magitek Terminals. Stepping into one of these will trigger the emote "Magitek terminal begins counting down." After standing in it for a short period of time, a nearby door will open. If you step out of the Magitek Terminal, the countdown will reset.
After the first boss, the hallways will have orange crystals with ground indicators around them exploding every few seconds. Standing in these will deal ~1000-1200 damage, so try to avoid fighting near them. You will sometimes find Magitek terminals located inside the blast radius of the orange crystals. I recommend waiting until the trash is dead, then healing the tank while they activate the terminal.

My group decided to play like all-stars and didn't get hit by Condemnation or Dread Gaze this entire fight. Based on past experience, I listed Dread Gaze as inflicting paralysis. I'll try to get another run of this dungeon in to be 100% certain.
The main mechanic on this boss is the same as when you encounter the All-Seeing Eye during the trash. Stand in the glowing purple circle which is located near a patch of crystals to reduce the damage taken from Eyes on Me. To make this task more difficult, the circle will switch to random crystals around the room after roughly two Eyes on Me are cast. You will know you need to switch soon when you see the emote "The power of the crystal begins to dim."
As soon as you see a new purple patch spawn around a crystal, move to it immediately. While you will have the buff Crystal Veil from the circles most of the time, there will be occasions that you will need to be running through the room to a new circle when Eyes on Me is cast. This is really the only time in the fight the party will take any significant damage.
While staying in the circles as much as possible, the tank should try to avoid the abilities Dread Gaze and Cursed Gaze. There will also be two types of adds that spawn: Mouche Volante and Amanuensis. The Mouche Volante have a frontal that deals very little damage, but should still be picked up and faced away. The Amanuensis have a frontal cone called Condemnation. We didn't actually get hit by this, so I'm not sure how hard it hits. Regardless, if it's like the Tam-Tara demons, it will deal fairly high damage, so avoid it as much as possible.

Taulurd himself is mainly a tank fight. He uses Double Smash very frequently, so you will be dodging a lot. Elbow drop, another frontal, is also used. While we didn't get by it, I expect it deals damage and stuns the target. I also saw him use Hot Hands, but I was not able to determine what it did. My best guess is it increases his damage done for a period of time.
The rest of the party will have to deal with the Deepvoid Slave's attacks. These enemies will stand on the ledge above the group and remain untargetable. They switch between two phases. In one, they spam Firewater, constantly placing circular ground indicators under the players. In this phase, spread out to minimize damage taken and dodge as much as possible. In the other, they will use Boulderdash, throwing unavoidable rocks at the party. You will just need to heal through this phase.

Bastraal is a heavy tank damage encounter, with random damage on the party to distract the healer. He will use Grim Fate on the tank frequently. This is a frontal, so face him away from the group. He will also use Grim Cleaver, which will hit a random target for ~500-800 damage, as well as Grim Halo, an AoE centered around Batraal. These abilities will be more than enough to keep the healer busy for the entire fight.
Three times throughout the fight, Batraal will have a thin, purple beam appear between him and a crystal. This will root him in place and prevent him from using most of his abilities, but will grant him access to Desolation. Batraal will emote "Batraal chooses his next victim," followed by marking a player with a small crosshair and firing Desolation at that player three times in quick succession. This ability will instantly kill you if you are hit, so you need to be ready to dodge. While this is happening, the crystal that he is connected to needs to be killed.
If you are melee, I recommend waiting for him to select a target before running to attack the crystal, as it is easy to hit the entire group with Desolation in the confined space. As a healer, I always moved to the opposite side of the boss so I would shoot Desolation in the opposite direction if he selected me. If the crystal is still up after three desolations, he will emote again and repeat the process until the crystal has died. The active crystal will always follow the same pattern. First, the crystal in the back left tunnel will activate, then the front left crystal, and finally the back right crystal.
After the third crystal has been killed, he will cast Hellssend, unlocking the ability Sea of Pitch and allowing him to cast Desolation at anytime. Sea of Pitch will place black pools under three random players. Move out of them quickly, and do not move back into them. I recommend dragging him all the way up to a wall. This will give the party as much room as possible to manneuver to dodge Desolation and to spread out the Sea of Pitch pools.
