I've been using 2 Ushi CEs and 2 Kintoki CEs with the support having another Kintoki CE. I tried doing Waver + Drake on Gilgamesh and hide Gil with Mash until they can reuse the skill once more. Please help me because I really do not know what team I should do.
As of now, I doubt a lot of people are able to clear the 3 BP raids anyway, so you don't have to force yourself to try to complete it.
Farm the 2 BP raids for gourds to get all the Ushi CEs while accumulating DP to get all the Kintoki CEs. The buffs from the CEs are essential to even deal a scratch for 3 BP. Don't rush and go at a comfortable pace.
First thing first, can you reliably do more than 1.5m damage on 3bp? If not, don't bother, you are just wasting bp. If yes, then, use stallers or tanks on your backline. The main goal is to stall for 15 turns after you deal 1.5m damage with your frontliner. Don't even think about killing her yet, you need more event CEs.
Now, your frontliner is up to you, you should know better who could do big damage with your frontline setup.
For your backliner, if you ever raised Georgios, rejoice, he can buy you 3 turns easily, every each one of the Cu and Herc with bond CE can stall Ibaraki for a few turns, swapping one of your frontliner with a healer could also help you buy turns while dealing more damage, or you can spam Waver's NP to stall Ibaraki's NP.
Don't kill the hands too quickly. If you kill the hands early on, ibaraki's damage goes up insanely. try to keep them around until you can finish all 3 at once, or at least until you can manage ibaraki's damage. I've noticed with hands I'm losing 500-1500 hp a turn. without hands, she hits me for like 4-8k damage <_<
edit: I don't know how viable this is for most people, but Orion is kind of my hero for this raid. I borrow a support waver, use a tamamo and orion and I'm killing her 70% of the time. A couple times I couldn't damage her enough and 2 times I wiped (seriously bad RNG...) anyway, I'm using 2 golden carps, (+1 one more from support), 1 MLB ushi CE, and two Kyohime CEs for gourds. If you find yourself unable to kill her outright, definitely bring a mashu and other stall servants for your back, I usually have waver/casko/orion kill her, if one of them dies, the rest of my backrow is geared for survival (pumpkin liz, mashu and iri)
I'm running the same except I put Marie, Mash, and Cu on my backline. Using arts team is fun, but sometimes RNG screws our fight with crits 😢
IKR?!?! sometimes RNG seriously screwed me over, I had a complete wipe because one time it was so bad. She crit orion every turn and somehow I got every buster and quick card but no arts...how does that even happen with waver and tama out at the same time? Q_Q
I think that all depend of your you team I have the same (2 ushi 2 Kinyori + 1 Kintori support), I tried to defeat 6M but I couldn't, I won because I survive the 15 turns but I only was able to make 3M of damage.
I am using Tamamo + support Wever + Shiki with Mash + 2 Cu at the end (FSN and Proto).
My other attaker and semi support is Nero (Bride) but I will use she once that archer hands changes.
