Okey, so I just did this as well. No problems as 5 BDKs 930-940 ilvl, could essentially ignore everything. Spend most of the time figuring out where the crystals to click were and what route I should be taking. Always had a good 6-7 minutes to spare when I reached the next one.

Never bothered to learn how to get it before; not like I would have used it, but I'll take it for the collection.
