I don't know if the regen can be avoided. Might just be a higher health threshold than the rage or how much time has passed in battle. It happened without enraging for me. I think they both have high defense to only the opposite attribute (kevesi one has high physical but no so much ether). The same applies to status resistances. The kevesi one has relatively lower resistance to ether debuffs. I managed to inflict Bind on it a few times so it pays to pair A's Cross Ray with Skyfoil. But yea, the blaze field is a nightmare. The Agnian one is easy enough to kill on its own, I accidentally ended up hitting level 99 trying to take them out before realizing they need to be killed together.
Are you using the warped white brooches? Rex already ignores defense on crits (which he should be doing all the time, especially with Glimmer's buff) so it's like a straight +30% phys damage for him. And make sure your breakers aren't wasting slots on break brooches since they can't be inflicted with reactions.
Managed to do it (and the last one too!). Good shout on the brooch. I forgot it went into negative values.
I feel like they were a little sadistic on this one. Why does the Agnian one fly around everywhere? I lost an attempt because, after getting it down to almost no health and focusing on the Kevesi one, I noticed it eventually got its regen buff active, so I switched to Shulk to purge that. But it took me ages to get in range because the bastard kept running, and by the time I managed it, the Kevesi one had unleashed a heat injection.
Which, yeah, the party just standing in blaze fields is
so stupid. The second blaze field art that has an absolutely gigantic radius is ridiculous. Really could have done without that one, Monolithsoft.
Imagine how easy this would have been if you could just task Shulk to focus on the Agnian one, and if you could order the rest of the crew to follow leader but still unleash all their arts?
It's like they designed it to expose all the most frustrating elements of the battle system.
Anyway, rant kind of over.
Last one was kinda cool. Borderline unfair and I got lucky with RNG and my breaks, but I'll take it. I never did find the accessory that extends the rage quell. It would be really funny if they just didn't put it in Future Redeemed, the one Xenoblade where it might actually prove useful lollol.
I agree with whoever said that these were the hardest superbosses. I think the first and third ones just flat out suck though, and the last two have some really frustrating design decisions that stop them being as fun as they could be. The psycho gargoyle with the debuffs was aight I guess, but someone please tell Monolith that Bind isn't fun. I will never do the QTE for that. My analogue sticks are too precious.
