General Information

On this page, we list all the abilities from the Trilliax encounter in The Nighthold. The idea is to give you a solid understanding of the encounter before you read the strategy.

If you are already familiar with the encounter, then you can skip to the strategy and tactics page or access any other page of the guide by using the table of contents on the right.

Trilliax is a 3-phase encounter in the Nighthold. This is a high movement, single target encounter that mostly focuses on environmental awareness. While it is mechanically uncomplicated overall, it can harshly punish players who make mistakes. Trilliax cycles through his phases in a time based fashion, meaning the raid will likely have to deal with multiple revolutions before finishing the encounter.

Arcane Seepage forms on the ground under random players as the boss is damaged. A purple circle will appear briefly before the Arcane Seepage spawns, giving players a moment to move. Once it has spawned, it deals low Arcane damage every second to players standing in it. They persist indefinitely, unless cleared by a Scrubber.

Trilliax will stay in this phase for 45 seconds.

Arcane Slash is periodically cast on the main tank. It deals heavy Arcane damage in front of Trilliax, which can be split between 2 targets. It also applies a debuff to the main target that increases damage taken by 35% for the next 30 seconds, and it stacks.

Toxic Slice spawns toxic cakes throughout the perimeter of the room. Players that come in contact with the Toxic Slices will apply a debuff that deals Nature damage every second for 20 seconds. This debuff can stack if the player eats additional slices. They persist indefinitely unless eaten. If Trilliax reaches the Caretaker phase or the next cycle of the Cleaner phase with Toxic Slices remaining, he will perform abilities that usually result in a raid wipe. Trilliax will spawn Toxic Slices every 30 seconds, for a total of 2 casts before the next phase begins. On Heroic difficulty and up, players will be Stuffed for 60 seconds, preventing them from eating another Toxic Slice and reducing movement speed by 25%.

Sterilize will only occur in the second Cleaner phase and any additional Cleaner phases after that. Trilliax will debuff several players, which causes them to inflict Arcane damage every 0.5 seconds for 40 seconds to anyone within 7 yards. If the damaging pulse makes contact with a Scrubber, it will drain 4% of their maximum Energy every 0.5 seconds and increase their movement speed by 70%. It will also cause the debuffed player to take moderate Arcane damage every 0.5 seconds.

Cleansing Rage will only occur in the second Cleaner phase and any additional Cleaner phases after that. Trilliax will destroy any remaining Toxic Slices and deal heavy raid wide Arcane damage based on the number of remaining Toxic Slices.

Trilliax will stay in this phase for 40 seconds.

Mana Rupture will damage half the raid every second during this phase. It deals light Arcane damage.

Arcing Bonds will link 2 players together, causing them to take heavy damage if they are too far apart. They cease to take damage when they are standing close together. Arcing Bonds lasts 30 seconds.

Annihilation is cast roughly halfway through the phase. Trilliax will jump to the center of the room and create a laser beam that comes out of the front and back of the boss. Trilliax will randomly spin in either direction, and can change direction during the 16-second channel. Anyone caught in the beams during this time will take extremely significant Arcane damage every 0.5 seconds. Trilliax will end the Maniac phase at the conclusion of this channel.

Trilliax will stay in this phase for roughly 13 seconds.

Succulent Feasts are spawned at the beginning of the phase throughout the arena. Players that eat the feasts are granted a hefty absorb that lasts 2 minutes or until fully depleted.

Tidy Up summons 5 Scrubbers to cleanse the room of Arcane Seepage and Toxic Slices. Each pool they scrub will grant them 20 Energy (25 on Heroic); if they reach 100 Energy they will begin to cast Cleansing Destruction. If this cast concludes the raid will take moderate Arcane damage. Players can interact with the Scrubber during Cleansing Destruction and prevent the cast, which causes the soaker to be the only one to take damage.
