As for the kabraxis, it is the hardest one out of 120, and it is pretty difficult, you need to learn the pattern how to move there, takes a while.
If you want to kill it fast, you need to do it later with much better gear, signets, and potentially all-in dps build. If you can kill it very fast, you play around most of mechanics in this fight.
Void really isn't that bad, you mean you got the ring, but have problems rerunning final boss arena? Getting there takes maybe 5 minutes, can just rush through everything. And ring you just get once. Most annoying part of the fight is the finishing move, if boss decides to walk other way, you can ruin the run, and it happens at the very end of the 20min fight, so you need reset whole thing, which is frustrating. But really as barb it is as easy as it gets, imagine doing it on class that can easily die in the arena if you don't move in time, being under constant threat of getting killed there. Barb has it far easier than pretty much any other class.
As for Laz, I was plying other builds, so I wasn't really trying it. Both strategies I know how to beat him, either In one pass without clearing totems (my prefered one), or one where you damage him, lose him, clear some map and continue, both of these are very difficult to pull off, and it can take many hours of trying to get it done. At least with my skill level and latency/lag I get to realm. If you check my videos on yt, I did run Laz in m17, which required open wounds, but it was quite similar to what it is now, and I killed him bunch of times deathless in one pass. But it was very difficult to do, those runs took me hours some days to pull off. Maybe I just suck, as there is guy who allegedly killed it 100+ times to get trophy. And according to him all he did was used his "pro moba" skills to control character
no new strategies or tricks to make it easier over what we already know.
So I feel im missing something here, because the way I kill this boss is very unreliable and significantly harder than any other boss from the list. There must be easier way, just I didn't bother to really investigate what you could do to get reliable kills now.
I could minmax gear, keep trying, score one kill lets say in 5 hours of doing it, post a video: here is how you do it. But what is the point, if ppl can't even kill kabraxis?
There is no way they gonna be able to recreate Laz run. Strategy I know is way too unreliable for standards of this guide.
