Main Differences from Hardmode
This fight is tightly tuned for nightmare with a very tight DPS check that forces you to utilize different strategies from hardmode in order to meet enrage.
Phase 1 – Tentacles and Larva
Unlike hardmode, Tunneling Tentacles on on nightmare mode have a very tight enrage timer of around 1 minute. In addition, tanks can no longer simply soak up the damage from exploding Unstable Larva adds carelessly as the explosion hits for about 51k damage if these Larva get near the tank.
This two factors means that you want to burn the tentacles down as fast as possible. For the second set Unstable Larva adds (Larva spawn based on a timer), kill the tentacles before dealing with the add.
When you get to the third set of Tunneling Tentacles, you can ignore and dodge the second set of Unstable Larvas as your raid should get pulled into phase 2.
Phase 2 – Hypergate Alacrity , Inconsistency and tight enrage.
The Grasping Tentacles in Nightmare mode gain a stacking buff called Hypergate Alacrity with every Slam that decreases the cast time of their Slam attack by 0.25 seconds every stack. This means that the longer you take to kill the tentacles, the faster their Slam attack will be, serving as an additional DPS check mechanic.
Each Grasping Tentacle spawn Hypergate Anomalies at 70% and 25% of their HP. This means that for every pair of tentacles, you will get four anomalies. Have just 1 DPS (melee works great for this) go around and killing the anomalies while the rest focus on killing the tentacles.
Lastly, at 50% of each Grasping Tentacle’s HP, they will cast a new ability called Creating Inconsistency. This will spawn a Hypergate Inconsistency orb always at the exact same platform. The player at the platform closest to the entrance) will receive a debuff called Inconsistency (healing received by 80%) and a green line beaming them to the Inconsistency Orb. This player will need to run to the orb to remove their debuff and the orb. This debuff it is probably meant for the tank who is coming to the entrance platform to remove their Scream debuff but if you put a healer there, they will get this debuff instead and can deal with it instead of the tanks.
Phase 3 – Furious Tantrum
Not much change from hardmode but you will probably enter this phase with the boss enraged or close to enrage. Make sure you kill off all four anomalies from the last pair of tentacles and use cooldowns. If the boss is enraged, it will one shot the tank so make sure to have a healer on the entrance platform with a battle rez ready to get them back into the fight as needed.
Reminder of Hardmode mechanics
If you are not familiar with the hardmode mechanics, here is a quick brush up for you. For a more detailed guide, please consult this guide.
- Split your raid into two groups to deal with the Tunneling Tentacles. Tentacles have a frontal atttack (Slam) and will need to be tanked away from the group. Additionally, you will want to damage both tentacles equally to deal maximum damage to the boss.
- One player in each group will also need to stand a bit far away so that they are the recipient of Acid Spit. They also need to position themselves properly to avoid getting slammed from the boss itself.
- Unstable Larva spawn from the back on a timer. These guys will beam for the tank and explode unless DPS kills them first.
- Hypergate Beacon will spawn and pull a random raid member to them. If the the Beacon pulls the same person more than 3-4 times, they will killed so DPS those down quick,
- Once both tentacles are killed, Birthing occurs to spawn a bunch of adds that everyone need to avoid.
- After 3 pairs of Tunneling Tentacles, the boss will pull everyone in for phase 2.
- Tanks will need their own platforms to tank the boss as he will drop spit on the tank, rendering the platform unusable. Additionally, the boss have a channeled Scream attack that deals a lot of damage and leaves a debuff on the tank that deals increased damage. Tank swap is needed here and the tank with the debuff will need to head to the entrance platform to clear their debuff.
- Pair of Grasping Tentacles spawn and will need to be killed by the DPS while avoiding their Slam attack. These tentacles will also spawn Hypergate Anomalies at 70% and 25% of their HP on random platforms that will need to be killed.
- Once the pair of Grasping Tentacles are killed, Hypergate Irregularity spawns on most platforms and will need to be killed.
- Once three pairs of Grasping Tentacles are killed, the boss enters Furious Tantrum phase
- During Furious Tantrum, the boss drops aggro frequently and will attack random raid members. Tanks will need to keep taunting to get their aggro back. This phase is mostly a DPS race before the damage overcome the healers.
