Some of the
Bloodline Ascendancies have been revealed and some of them are fucking
juicy.
Farrul has a node to make Spectres prevent your action speed being reduced below 100%, giving another avenue to becoming action speed immune outside of Jugg, Trickster, or using a Temp Chains Balance of Terror.
Lycia has a mini Original Sin (50% vs 100% ele to chaos), making chaos conversion builds significantly stronger on a much lower budget.
I don't see the value in the
Delirious one, but I'm sure someone will cook something silly up. There's probably something with the Schizophrenic Dissociation node on a Cast When Stunned build, I'm just too lazy to do the math to see if it's worthwhile, and I'm not totally sure how it functions in practice (if the damage you take in 4 seconds is removed from life, treated as a hit, etc). Edit: I forgot about it disabling non cluster jewels while writing that. That's a
rough cost to deal with, so I'm doubtful it'll get used in CWS builds since you rely on jewels for more max life, ignite chance (before tattoos), and so on.
Catarina is all minions and I don't play minion builds, so I can't give an informed opinion on that one. Immediate thought is Prolonged Servitude could make for some silly shenanigans using Infernal Legion support.
Aul is definitely gonna be an interesting pick on charge stackers, but might not be powerful enough to justify finding Aul (or buying a carry). It can also be decent if you're doing an armor stacker and haven't invested in frenzy charges... but you should invest in frenzy charges. Still, might be worth it if you're still on a lower budget and don't have enough aura effect yet. Other side seems a bit rough. By the time you can unlock it on your character, the only one I see having any value is the action speed immunity if you have no gems in your boots, but that's a hefty cost compared to doing Farrul and just having a spectre (which you can probably make tanky enough on a 2 or 3 link anyway)
Olroth bloodline is all about Ward. I have never played a Ward character so I have zero clue how good any of this is. Boon of the River might be decent, besides that, make up your own mind.
Edit: To no one's surprise, the forum thread is full of people who have never played a build that wasn't stamped and approved by Rue, Ziz, Mathil, or [insert popular streamer here]. For the most part these aren't world shaking, game breakingly over powered ascendancies. They're generally niche, and there's issues with some having stupid downsides yes, but for the right builds, a lot of these are busted strong. If you've never played an armor stacker, you might not realize how fucking
insane 50% grace effect is. If you've never played a Replica Alberon's Warpath focused strength stacker, you might not realize how beyond busted 50% ele to chaos conversion is (there's a reason Original Sin costs over a mirror, and it's not just cause it's hard to get).
