Yesterday after about 125 attempts I was able to kill Zekvir ?? Solo. I got the achievement for the title, but not the achievement for the mount “Let Me Solo Him”. I was the only one in the delve for the entire fight. I opened a ticket, but they don’t seem to understand at all, they even told me “you needed to do it on a lower difficulty”, it honestly read like something from ChatGPT. Can anyone help?
(Had to change the title to ?-? Because it won’t let me post ??)
If you did it after 10pm, then the achievement was likely disabled as part of the end of season 1.
If that was the case it wouldn’t have given me “Hunting the Hunter”, which is also a season 1 achievement. It gave me that and the title, but not “Let Me Solo Him”.
That really sucks.
I can confirm that Let Me Solo Him was still being awarded after 10pm last night. Not sure why you wouldn’t have got it if you were alone in the delve.
From the Blizzard article on Season 1 achievements, it appears there’s still one more week left to get this one.
The only thing that was different for me was that there were no chests in the reward room, as S1 crests have already been turned off? But the boss did drop the void schematic.
Were you in a group, and just solo in the delve? That’s the only thing I can think of that may have caused it.
Yeah, I’m thinking that was the issue, I think I was in party with someone that was offline outside the delve from other stuff we had been doing earlier, but when you’re in the delve it only shows Bran. I even took screenshots, but I doubt that’s worth anything. Even if that’s the case I feel like this is a bug.
I dont think zekvir’s lair will be accesible after the servers come back up. And doing it as holy where you have to rely on Bran to interrupt makes it a massive dice roll each attempt. I had multiple where I had done way more than his total health pool, but Bran kept missing interrupts and letting him heal. Heartbreaking attempts where he’d go from 10% back up to 70% as Bran missed interrupt after interrupt locked into an animation flying around like a clown.
I kind of knew trying to get support for this would be impossible, but maybe it can offer some solace to anyone else it happened to that they’re not alone. 
The following achievements will become Feats of Strength when The War Within Season 2 begins and the associated rewards will no longer be available to earn:
…
My First Nemesis: Defeat Zekvir in his lair before the release of the next season of delves. (Reward: Zekvir’s Raptorial Spine (becomes a low drop chance with Zekvir kill after the end of the season.)
…
Let me Solo Him: Zekvir: Defeat Zekvir in his lair on Tier ?? without any other players in your party, before the release of the next season of Delves. (Reward: Mount Customization: Delver’s Dirigible Schematic (Void.) Becomes a low drop chance with Zekvir kill after the end of the season.)
My read of that is that Zekvir’s Lair should remain available this week, with one last week available to get achievements before the start of the next season. It also implies that Zekvir will remain available in S2 and beyond, but with these achievements no longer possible to get.
What is unclear to me is impact on drops this week, as we’re technically after the end of season 1 (10pm local on Feb 24) and before the beginning of season 2 (Mar 4). Maybe I just got lucky last night with a low drop chance on the void schematic?
Also, I can’t imagine having to rely on Bran for interrupts. Was annoying enough to rely on him to consistently dispel…
