It took us few evenings to train him. Yesterday we finally got him. Only Dreamwalker now, final bosses from each section and then Cold Nose himself.

Thanks to kills from this week, we have first Shadow's Edge in Dusk. Next part on the way to Shadowmourne is to kill 1000 trash mobs (A Feast of Souls) and then more funny parts with final bosses from each wing.

Well done! Looks like we're on our way to our first ever dusk legendary...

On our way indeed, although judging by quest chain the part done isn't toughest.
