Bug or i`m doing something wrong?
This is surely bugged, I did it 3 different ways already, and never got the achievment…
- I killed all tentecles at once with 1 spell -->no achievment
- I killed all tentacles in 1 turn but not at once -->no achievment
- I killed all tentacles in the opponent’s turn → no achievment
It is really annoying now… I think its impossible to get this achievment currently… I saw videos where it worked when ozumat had any hp… but now he has no hp, only tentacles and the achiemvnet never works now…
Oh man, I just managed to kill all 7 tentacles in a single turn, with a fantastic to watch Spammy Arcanist setup, but I didn’t get credit for it. These have been the most infuriating 2 hours of my life. Thanks Blizzard 
Same here, fought over 4 hours and had done that one-turn kill twice, no achievement. I do not know whether the devOps have done any failure tests. Please do review your code for the determination.
Confirmed. Still bugged.
Glad to know I’m not alone… just completed it tonite with no achievement 
I think its bugged since the boss doesnt have any hp… they should fix it…
