"So there I was, a level 15 Warlock facing two godlike characters with a combined total of 120K HP..."

Do Khorvax and Killion randomly spawn in this mod?

I was playing through the story, and when it came time to take the north passage from the enclave (Frosted Hills, I think) as soon as I stepped through the gate Khorvax and Killion were both standing RIGHT THERE, blocking the way, along with a half dozen pairs of spectral swords. It was impossible to run past them so I had to fight them--repeatedly. I probably died 20 times just trying to clear them from the path so I could progress the story.

Thought I should bring this to your attention. I don't mind the random spawn, but spawning at the entrance to the lvl 12-13 areas is nucking futs!
