Solo old torghast, but it blocked

Gameplay Dungeons, Raids and Scenarios

I wanted solo all torgehast.

Was a bit runs. When try more and it say “you do not meet the requirements for this dungeon”

What this mean?

Edit: Seem it mean I cant “skip” layer. Like i tried queue 4 layer (before I did 2 layer), it dont let me in.
When queue 3 layer seem worked

If I got this right, then you can’t queue for a layer before completing the previous one (in your case L4 - you would have to complete L3 beforehand). You won’t have any issues blasting through the layers now as its faceroll, I’m running Torghast myself for missing achievements
