General Information

Welcome to our World of Warcraft encounter guide for Trilliax in The Nighthold. We will teach you everything you need to know to defeat the boss in every difficulty.

To make it easy to navigate the guide, we have split it into 3 pages:



Trilliax is the third boss in the Nighthold.

Trilliax, once proud servant to the nightborne aristocracy, has been discarded and left to slowly deteriorate among other surplus constructs. While an unwavering will to carry out its tasks remains, the passage of time has splintered this construct's personality matrix. It now unpredictably switches from one mode to the next, ranging from doting caretaker to homicidal sterilizer, craving recognition and validation from a master that no longer exists.



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.

Mythic Notes

  • Trilliax's Imprint will appear occasionally, and perform abilities opposite to his current personality. If it reaches full Energy it will wipe the raid.

Bloodlust/Heroism/Time Warp

Bloodlust Icon Bloodlust should be used when engaging Trilliax, as there are few mechanics taking place and movement is at a minimum.
