I got invincible on my first try, and I wasn’t even supposed to be there, one of my boosters was doing it, we were waiting for her. Then I decided to go do it too, and I was trolling saying the bosses talked to me saying I would get the mount, and I get it.
That’s what I said: I wasn’t able to change the difficulty while inside, but after I stepped outside I could. So I’m convinced the Invincible skip still works.
Confirmed today that the ‘skip’ still works. I don’t know what you’re doing wrong, Cov, but it shuold still work. Are you staying in the group with the locked character? That’s essential. You should NOT leave the group until you’ve defeated Arthas.
I’m pretty sure you have been doing 25 normal on all your tries this week. I’d suggest you check more carefully on your next try just to be sure, but no way of skipping to LK is working right now.
