This is a good thread. I like this thread.
I doubt that Xau would actually be the boss itself; she'd probably take on more of a role like Edda for the last boss fight of Tam-Tara Hard. Her combat classes are arcanist and scholar, so her boss fight would likely revolve around what she summons, but I don't think it would straight up be carbuncles or faeries, exactly. Let me expound upon my ideas.
Xau's general profession, outside of combat, is actually more of an historian, and she specifically specializes in the history of the Fifth Astral Era; that is, the era when Mhach, Amdapor, and Nym were all at their peaks and engaging in the War of the Magi, and when black, white, and arcane magic were all reaching for higher and higher heights in an attempt to outdo one another in the conflict.
Miss Dolabnha is also a rather... Curious type, to say the least, the kind of person that can't resist pressing that big red button because she just has to know what it does. So, one day, on an expedition into a ruin of the Fifth Astral Era, she finds some dusty old tomes in Amdapor or Mhach or Nym and, oh dear, what does this say? Research into combining the magics of all three magocracies? And no, no dear adventurer, this is not like red magic, this is not like red magic at all. This is talking about combining voidsent and faeries, voidsent and elementals, faeries and elementals.
Any sane person would tuck such a tome away into the depths of a library and never open it again. Xau, though? Too curious. Far too curious. She knows, though, that those close-minded imbeciles around her wouldn't allow such a thing, so she takes residence deep within some Amdaporian, Nymian, or Mhachian ruin, and starts her experiments.
After a while, though, the locals would doubtlessly notice some horrific abominations starting to creep out of said ruin, and would request somebody to go in and find out what's happening!
And that's where the party of adventurer's come in. Descending into this ruin and fighting off chimerical monsters that combine void and elemental, faerie and void, faerie and elemental.
First boss of the dungeon: Triple carbuncle fight - Emerald, Topaz, and Ruby, but all corrupted with void energy. Each would function as they normally do when summoned by an arcanist - Emerald for ranged attacks and knockback; Topaz for melee and stun; Ruby for melee and DoTs. There might be some other mechanics, but the big challenge would just be fighting three at once. I'd say that only Topaz has an aggro table, and the other function as independent enemies that only do AoEs; Emerald's would be telegraphed, but Ruby's wouldn't be.
Second boss of the dungeon: A horrific combination of a voidsent and an elemental, gone completely mad from the anathemic joining. The major mechanic of the boss fight is keeping it balanced between void and elemental energy; as long as there's an equal amount of black and white mana flowing through it, it can't use either effectively because the two forces are fighting each other within; if the balance tips too far to either end, though, then it can start using strong black or white magic attacks depending on how it's tipped. Maybe something to do with preventing adds from touching it, or some kind of tethered orbs, or something along those lines.
Miniboss: Every dungeon needs a miniboss between the second and third bosses! An opal carbuncle - a carbuncle infused heavily with holy magic; standard enemy, but strong and with a few AoE attacks.
Final boss: Xau, with both Eos and Selene forms of her faerie; Eos has been strongly infused with white magic, and Selene has been strongly infused with black magic, turning them into completely different beings than their normal faerie forms.
1. The faeries have no aggro table, and instead roam around the arena on their own as they cast a LOT of AoEs.
2. The arena is divided into black and white sides. Eos can only be harmed when she's on the black side, and Selene can only be harmed when she's on the white side; otherwise, they're invulnerable. There would be some ways to force them to one side or the other, ideally, maybe some interactable objects.
3. Damage needs to be split roughly evenly between them; if one of them is much more damaged than the other, then the other will heal them up.
4. Did I mention lots of AoEs?
This post is kind of dumb in retrospect but I spent too long writing it to scrap it all so HERE YOU GO.
EDIT: During her personal boss fight, she'd probably be saying a lot of stuff like "YOU'RE INTERRUPTING MY RESEARCH!" and "NARROW-MINDED FOOLS, YOU DON'T UNDERSTAND!", and lots of ~MAD SCIENTIST~ stuff like that.
