My personal opinion: Crucible of Eternity 2nd path is terrible
Is this the teleportation lab one?
I was in a relatively good group, and it all went fine until the last boss.
The boss before the last can be beaten easily with a trick – just look for an environmental weapon and see how to use it.
Now, Subject Alpha is pretty hard. But if you don’t dodge the fire AoE(save endurance for ice) – you have plenty time to walk out – and take down crystals the moment they go up, you should be fine. You don’t need to walk out of ice either – there is a right moment when you can dodge and evade it altogether. The difficulty is that you can’t help downed players(because you’ll inevitably get targeted by another AoE) and that if at least two people screw up, you probably lost since crystals don’t go down as fast. And yes, it did take us an hour to get good at dodging all that, but we still did it.
