Are you absolutely sure you killed every trash mob? I find it easy to get turned around there. I can try to look at the logs when I can get to a PC, but I never actually counted how many mobs there are.

I’ve run the speed run and no death for several people in the past few weeks, including before and after U46. (There are three of us offering the fourth spot to guildies who need achievements, and the speedrun/no death/hm achievements here are very popular requests.) The person requesting the achievement has always gotten it. On one of the more recent runs we almost missed a trash pull we normally remember to do just fine, which is part of why I’m asking.

When we did MHK the other day, we did not get the no-death after the final boss despite no players dying. We had to backtrack to find a lone werewolf behemoth chilling in a side hallway. Killing him made the achievement pop.

Can we get that part added to the achievement text then??? Because the achievement says specifically just the Bosses. Nothing about mobs or trash packs and there a TON of extra trash packs in some dungeons.

Here’s an example of an earlier DLC speedrun achievement description that specifically says only the bosses, for comparison:

“Defeat Zatzu the Spine-Breaker, the Mighty Chudan, Xal-Nur the Slaver, and Tree-Minder Na-Kesh in Veteran Ruins of Mazzatun within 30 minutes of starting the dungeon. Timer starts on passing through the first archway.”

No mention of “encounters in addition to [the bosses]” in this one, and the trash is accordingly not required in RoM (besides whatever unlocks the doors to proceed).

The good news is that if you kill the end boss and the achievement doesn't pop, you can go back and kill the mob you missed, which in my case, turned out to be a hulking werewolf in a side room we hadn't realised was there.
