Most orbs you spent on one banner

Most Orbs I've used on one banner was probably ~150 Orbs on the B8% banner with Spring Camilla.

I got neutral Spring Camilla, defense-.boon Hector, and a +Spd/-Atk Bridelia... who I foddered off.

Regrets everything

I think the most that I spent was 180+ orbs on the L!Lyn banner. I ended up getting 6 5-Star Heroes in 2 H!Jakob, 2 L!Like, L!Grima, and Genny. (I was mainly aiming for Colorless since I wanted all 3 Heroes, and I managed to get them all along with some Warding Breath fodder, so I was extremely happy about that.)

CYL2 over 300 orbs for Lute, Minerva, Micaiah, B!Ephraim and with the 20 orbs today I got...
Legault... a friggin Legault at least I won't have to 5* one of the four 4*'s I have to unlock his conversation I guess...
5 5*'s isn't as bad as my luck on the Sketchy Summer Banner though ~ 250 orbs for Minerva and a -Spd Mia.

Hmm... Probably the first Legendary Lyn banner, used somewhere around 200 orbs for a -Spd +HP/Def SM! Eirika ( ' u ' )
There might be a banner where I used more, but those 200 orbs have just been haunting me ever since.

Around 400 F2P Orbs on the Lene Banner, without getting her...and another 400 F2P Orbs on the Flying Olivia Banner right after...also without getting her (and also nothing else on both banners).

800 F2P Orbs for I believe a bad IV Ares and bad IV Katharina...not sure, why I even kept playing the game afterwards.

About 540 so far, on CYL2. Will likely put in my remaining 140 into it before its over. All F2P orbs btw, haven't summoned in like 2 and a half months.

Didn't get a single merge for my arena team unfortunately. (roy, nowi, fae)

For me was this CYL2, with 300 orbs i got 7 5*, till now my luck has never been that good

Around 450 f2p orbs on the legendary lyn banner, and I had pretty insane luck. Don't remember exactly all I pulled, but I think it was like:
x1 Fallen Celica (bad iv's, so used for chill spd)
x1 L!Ephraim
x1 Genny (+atk -hp)
x2 H!Henry (+spd -hp) (I'll talk more about him in a bit)
x2 H!Jakob (+hp -def)
x3 L!Lyn (+res - hp)
x2 L!Grima (+hp -def)
x1 PA!Shigure (+atk -hp/def)

I was super stoked with the outcome, I never really have this luck. Also, all the units I got were super fun to use, either as fodder or in-game, so it was definitely my most fun summoning session. Couldn't freak out cause I was in class though lol.

Buuuut now I have ~800 F2P orbs saved up so far for the Halloween banner re-run because I want to high merge Henry. He's so much fun to use, especially with CC from the free Takumi. I think I might be able to manage to get at least 200 more orbs before his banner for a 1000 f2p orb session, and I hope to get 9 of him (which is unlikely), but I'll be happy as long as I get at least one with better IV's. After that I'm gonna save for the Christmas banner re-run so that I can summon for W!Tharja to give him Vengeful Fighter for his build to be complete.

700 f2p Orbs for CYL2
Focus Results:
2x B! Veronica
1x B! Celica
1x B! Epharim

Pity Breakers Results:
2x Lute
1x L'Arachel
1x Hardin
1x Nephenee
1x Deirdre
1x Sonya
1x Faye

I'm planning on saving until the last day of CYL 2 and snipe colorless for Veronica.

cca 200 orbs on this CYL banner.
2 B.Ephraim, B.Veronica, Hector regular. And chose B.Hector. 3/4 already in my team. I'm really satisfied. It took me cca 4 months to have 3/4 of the first brave heroes and still don't have B.Lucina.

200+,I spent exactly 200 on CYL.

CYL I got 6 5*
B hector
B Ephraim
Veronica
Sanaki
Nephenee
Y tiki

Free summon was celica

280 orbs, no 5 stars. Luck is a word, nothing more and nothing less. (Hero Fest 1)

350 some orbs on Ephraim's Legendary banner. I got up to 15% pity rate and got pity broken by someone I didn't want/need. The other 9 pulls were also kind of meh aside from L!Ike for a merge.
The most I've spent (so far) on a non-Legendary banner is this Hoshidan Festival banner. I spent around 260 orbs and pulled Nine 5 Stars: 4 great new off-focuses, 2 focuses (Elincia and Micaiah) and three non-focus repeats for merges and such.

for me it was the spring banner. I spent over 200 orbs trying to get Spring Catria but didnt end up getting her. I did get 7 5stars, none of which were focus units. I'm still salty about this
