Xeno 3 (spoilers possible ig?)

I just found out people on this website play xeno trilogy, so... anyone played xeno 3 to post game? If so, can you share your builds? I'm grinding seraphic ceratinia's level challenges and am on lv190, but can't get past no matter how lucky i get with chain attacks, its attacks, etc.

All level 99, 100% ouroboros, whatever accessories i randomly found already
Builds (class only)
noah - zephyr
mio - lifesage
eunie - full metal jaguar
taion - incursor
lanz - war medic
sena - ogre
hero: ashera

Or you can critique the classes i assigned if you have any suggestions.

hopefully someone has something, i'm getting way too annoyed at blue and white pixels on a screen.

i can also help if anyone has problems with the game, i'm pretty good at the rest of the game, besides seemingly only this lv190 ceratinia fight. it's on normal mode...

i would go to a forum, but their topics are all locked bc this game is 2 years old

Admittedly I'm only up to Lv 160 for a few reasons:
- Battles took too long lol
- My gems and classes are low
- The blue and white pixels you mention
- That high pitched bird in the background that plays every 5 or so seconds
- The main reason, and this is kinda spoilers:


The party I used to defeat the Lv 150 was:
Noah - Swordfighter
Mio - Lifesage (I needed heals)
Eunie - Lone Exile (I usually run FMJ but everyone else was dying fast without this, would like to change this)
Taion - Signifer (passing around buffs incl cross impact (power charge) in his fusions arts, kinda just copied Enel)
Lanz - Heavy Guard (which is weak iirc, doesn't seem to take aggro well but I don't have any other high classes for him)
Sena - Ogre (break)
Hero - Lifesage (her heals are good and she can revive everyone in a chain attack)

I would say Signifer is pretty important to have and is one of the best classes for a reason. I also wanna try Soulhacker but haven't started the grind. You may also wanna watch the video below because it's kinda nuts, and it shows the entire build. I haven't implemented any of this in my party yet.
Lv200 Hard Seraphic Ceratinia in 10s

I'm clearly not as good as you for XC3 so my advice may not be the best but hopefully there's something.

i see, a fellow ceratinia 150 guy... i was only going to do up to 150 for the m armor like probably 99% of people getting ceratinia up to 150, but my friend went past to 200 and he's being annoying about it, so now i'm trying to get to 200.

i'll try the video see if it works out for me. thanks anyway, might try out lifesage as hero, but then my chains will prob only max out to about 5mil instead of 7-8mil... trial and error ig.
