So I just upgraded to a level 3 Gladiator’s Sanctum in my Garrison and after a lot of research I found out that once you unlock level 3, you can queue for the Highmaul Coliseum Scenario via an NPC in your Glad Sanctum or Kharg just outside Highmaul in Draenor-Nagrand.
However, the NPC in my Sanctum doesn’t have anything new for me, there is no new NPC, and when speaking to Nagrand Kharg it simply says “Kharg seems uninterested.”
After a lot of digging on WoWhead the most recent articles and comments regarding how to do this content is from Legion and BFA launch most of it involving level-capped characters, and I cannot see any possible way to queue for this content this expansion.
Somebody told me that you need every single Nemesis Quest (all 7) done before you can access it, but that seems like a steep entryfee for a for-fun game mode scenario, and I’m not sure if that’s correct.
TL;DR if you have a Glad Sanctum does Highmaul Coliseum work, and how do you even queue for it in Shadowlands?
