Wew. Managed to do a 3 BP stall with a MLB Ushi CE and one Carp.
[attach=1]
Used the recommended Orion/Waver/Tamamo stall comp with Mashu, Georgios, and Cu backline. Waver died about 5 turns in when everything hit him including the left arm NP. Orion died about 3 turns later when the right arm NPed... and I didn't bloody know it was an AoE NP. Had the Mashu Taunt/Invul up thinking everything would be good.
And then down to the home stretch:
[attach=2]
I burned 2 command seals to have Cu NP each arm. Along with the Gandr stun and then activating Cu's dodge, barely clutched it out. I'll wait till I get a few more Carp and my seals regenerate before I try that again.
By the way, Guts is still useful for non-NP Ibaraki turns because one of the turns before, she one shot Cu with a crit hit.
I spent 90 quartz and got 2 5* CEs, 1 4* CE and my 2nd Fran. No sultry drunk oni unless I get lucky with the event tickets.

Lastly, any of you on my friend's list, can you leave one of your supports with the +50 bond CE on during events? (I know ditt did). I always find it illogical during events when people give every single servant of theirs an event CE. Chances are only 1-3 of your possible servants will get picked for the event (Caster and All usually). Why put a Carp on that lvl 40 Robin Hood which has a 0% chance of being picked? Put the bond CE on him, or the Friend Point CE on him and that 0% is now non-zero. Since AP isn't really getting used this event, I still need to use AP up farming embers or mats.
Is this event going to completely destroy me, or will I be able to do something on at least the lowest difficulty? :derp:
The lowest difficulty I think has Ibaraki at 300k hp. Any friend you use with a Lvl 80+ attacker and an Ushi CE can singlehandedly carry you. The medium difficulty (2 BP) is 1 million HP and can eventually be done once you balance out how to support your high level attacker. You would either call in a Lvl 80+ friend attacker and support him with Irisviel and Hans Andersen. Or you can try to make Emiya your attacker and borrow a Lvl 90 Zhuge Liang/Waver to buff Emiya.
My ID is 252,310,197. This is an open invitation to all. I've got 5 spots open now so I'll check in and see if people want to get added if you let me know your ingame name.
