So I FINALLY just beat Nexus-Princess ?? Delve 1 week before the season ends. It took me over 135 attempts before finally finishing. I got the new title and mount 
I have to say, this is one of the most fun encounters (on retail) I’ve done in SO long. The difficulty, soloing experience, and the vibes of the exclusive rewards. I absolutely loved this, thank you for making that fight.
It was fun after they fixed the positional requirements of you facing her clones to be a bit less razor-thin. I’ve also completed it a few weeks ago. I’d say it’s the worst of the 3 Nemesis bosses so far, but it’s not too bad I guess. Zekvir and Underpin were better. I didn’t even bother with it with the old clone responsiveness, some of my deaths just felt cheap and stupid. You could be almost face-on with them and still get clipped somehow. 
This was easily the best of the 3. Zekvir got nuked from orbit and tuned for people who had barely gotten to endgame. Underpin could be outgeared to the point you didn’t even have to do the mechanic of the fight.
And it’s not even close.
There were no gimmicks, no random factors, nothing out of your control that could prevent you from winning.
I absolutely love a challenging fight where the conditions of victory and defeat rest squarely on whether or not I played well enough to win.
The entire fight is a gimmick lol. It’s a skill-based gimmick mostly, but gimmick nonetheless. It’s a 5-8 min rhythm game, and you get 1 shot if you fail the boogie.
Before Blizz tightened the clones laser beam line of sight, the fight sucked. The other 2 had clunky mechanics too, but since everything KyVeza does is a 1 shot, they were nowhere as egregious.
Eh. I still preferred that to “This literally doesn’t matter if you have ilvl” or “You can sneeze on the add and it’ll die”
ilvl still helps a lot with her. Instead of having to dance for 10 mins you dance for 5 mins. And less shell games to screw up on. Especially before they fixed the clones.
Yeah it does. But it doesn’t let you ignore the mechanics because they don’t reach a point where they have any meaning. Also the “DPS checks” on Underpin and Zekvir were so low that you didn’t have to plan for them at all. At least Kyveza didn’t fail to have a dps check, it just chose not to have one.
Honestly I just found the previous two too easy to be fun.
My eye sight isn’t the best, so I choked on the shell game every now and then. Didn’t really feel like it outplayed me, it just got away from me. Turning off my UI helped a bit with all the visual noise, but that didn’t really feel all that interesting either lol. I hope they don’t make fights like her the norm. Or at least don’t make purple adds in a purple room with purple floors 
The knives and adds was pretty easy to deal with, but before the cone change the adds felt clunky af
Also the mount looks kinda lame for the effort, but that’s another story lol.
It definitely was the hardest of the 3 for me to kill, but mostly for the wrong reasons.
Congrats!
I felt like this one was significantly easier than s1 and s2, but I was probably severely undergeared for all 3 lol
No, it isn’t. All you have to do is play the game. There are no eggs spawning in bad places, there’s no bombs you have to kick with all of the issues they introduce, there is nothing except using your character’s abilities and correctly executing boss mechanics.
Exactly. Everything happening in the same order, the same way, nothing random, and no way to outgear your own personal failures. Do it correctly and you win, make a single mistake and you lose. Excellent design.
Of the 3 delve bosses, this was by far the most fun AND frustrating of the batch. I would love EVERY delve season boss to be this straight forward (as no, no silly gimmicks that are purely RNG for RNG sake).
necroing this post (technically) to point out to poor souls still wanting to do this fight:
The title is still available currently. The mount, and the “let me solo her” FoS are gone, but “Pruning the Princess” acheive and “Contract Killer” title are still active.
The shell game is and has been one of the real pain points of the fight, but there is a way to make it easier on you:
Don’t use your whole head or eye movement to try and track Kyveza, this is part of the trap. Trying to track her by actually moving your toon or your head increases blur and overlap. Instead, orient your character facing where she starts. Orient your camera to be almost perfectly vertical overtop your character. When Kyveza jumps, your eyes are centered on your toon.. you will still see where she goes and if you can track her first jump while not moving head or eyes, you will be able to follow her for all of her jumps. Once I started doing this, the shell game easily got 75% easier. You should already be doing this fight with minimal particle effects or extra graphic settings to reduce unnecessary visuals so excess target blurs should be all-but eliminated.
Also, if you play a class with high self-sustain/healing, you can set Brann to damage dealer and effectively halve the duration of the fight. For context: My DH is 157ilvl, averages about 17 to 18k dps… when I had Brann set to healer, I consistently getting Kyveza to 79 or 80% by the first shell game. And that pattern mostly continued. With Brann as damage dealer, she was entering first shell game at 65% consistently.
Hope all of this helps.
If your issue on the fight is straight throughput and not the mechanics, I recommend re-arranging the timing of your CDs and pacing of damage. Again using my DH as an example:
Open with The Hunt, use a Fel Blade and then run since we know the fight opens with daggers. I only use through glaive/Reaver during daggers.
when she transitions to nether portal cast, I use Eye Beam and basic rotation (but I don’t use vengeful retreat).
Once portals are ready to spawn, I am in the spot I need to drop it and then VR out of the bad circle. It is at THIS moment I pop the big CDs (Meta, Potion etc) and go absolutely HAM. This will continue as she transitions to dark Massacre.
During Dark Massacre, the shadows will follow you if you are facing them. With this being the case, you can face each one and then use strafe to get the boss back in front of you, allowing you to maintain damage rotation while properly performing the mechanic. It also sets you up to know exactly where the first daggers will fall (the first ones ALWAYS spawn under boss and face you).
after the first wave… I could reliably run the CDs in sequence:
Every nether portal I had eye beam
Every 3rd portal I had The Hunt
Meta at least once every cycle between shuffles
And it made a huge difference, and makes you less likely to suffer from summit fever and try to pop something early hoping to get that last hit (which is guaranteed to lead you into a death)
Enjoy the Pre-Patch.
