Final Boss Fight? WTH?

[Martoq]

What is up with this fight? I get some enemies down to 1 HP and they refuse to die. My heroes don't counter even thought the card I used said they would counter. An my FPS drops down into the upper teens low twentys FPS, been running at 60 FPS for the whole game until now.

How do I beat this cluster screw of a boss fight? I swear at one point I must have had close to 30 enemies on the screen from all the cloning that one enemy type does. They kept cloning the ones who don't die unless you kill the ones they are connected with. By the time I got to the last phase I was pretty much DOA and had no way to beat it. All this and on the Story difficulty. Got a blasted headache from the dodgy FPS and wasted almost 45 minutes trying to complete it.

Any tips or suggestions would be appreciated.

Final mission has technical issues. Save/reload can help - you may need to do it again when the issues re-occur. (Would say bug report but we should get a patch on the 26th so that may pick up on this.)

As for gameplay tips, hard to say because so much depends on who you've got and what cards they have in their deck. The cards you can collect from killing mobs are very powerful though, and can give you an advantage. Remember too that in the second phase that the objective is the objective - you don't need to kill all the things, just those needed to get to the next stage.

Yeah the performance on the last fight is atrocious. No way to fix that, lowering the graphics didn't matter much for me. It still stutters most of the time.
Gameplay-wise I always prioritized the elites, since when they get duplicated they lose 50% HP, so any damage done beforehand is good. After they duplicate it usually takes one ability to finish em off. I do agree it is dumb as hell that when they get cloned they also get added to the soul link web of madness. Try and focus them off with items from the start, because once there are like 4 monsters that are part of the soullink chain is it almost impossible to KO them all with only 3 card plays. Do keep in mind that they have a shared HP pool. So even if they keep linking souls, eventually they are all one-shottable.

Still, the end fight is an unbalanced mess and really takes away from a otherwise great game. I haven't managed to complete it yet, because my save files won't load the fight, but honestly I feel better not finishing it. That fight was frustrating as ♥♥♥♥.

I did it on Heroic II diff, first try and I didnt even grabbed proper mods. Few times it was like im totally screwed but turned out manageable. The last part was the hardest one but I think I shoud've focus on the main targets more, before those guys duped everything x2.
Used Dark Hunter build.
Took me around an hour, with all those freezes occuring after someones abilities cast etc. SO i was constantly reloading after fps drops.
