Subject 6 Deep-Sixer
When it becomes a pancake, he will block everything, gaining up to 20 stacks overload. Let him get 20 stacks through blocking, then stop attacking. Starting with the 21st hit, he will explode when getting hit. So it requires a bit of timing etc.
Thanks a lot. Will give it a go.
20 is not necessary. You can get him to 19 stacks and still get the achievement. But aside from that, everything Novaan said is correct.
The best way to do it is to have everybody stop attacking when he blocks, aside from 1 – 2 people designated as the stack buffers. Disable autoattack and manually click the skills to make sure you don’t over-attack.
Wait till Subject 6 is down to about 5 – 10% health first, then wait for him to block before building the stacks. Then, drop Time Warps/FGS etc. and burn him down as fast as possible once he stops blocking.
We had to do it twice in order to get the achievement, for some reason it didn’t work properly. We once got him to 19 and then to 20 but no achievement was unlocked. On the next day we got him to 19 again and we got the achievement. Another one of the Gw2 mysteries o:
Also, you have to make sure he doesn’t do any of the exploding if that phase happens more than once. So for example, if you do it to 19/20, and a second time around he explodes, you won’t get the achievement.
At the same time, if he explodes the first time around, you can get him to the phase another time, and get to 19/20 and still get the achievement.
Actually, that’s not true, domness. When I got the achievement, we had to “reset” a few times because we accidentally made him explode, but we still got the achievement in the end.
This was a few months ago though. It’s possible they may have stealth-patched the achievement.
When I got the achievement forever ago, we got him to 19 stacks, waited for him to stop blocking, and then killed him while he still had his 19 stacks.
