Kama at 820 quartz. F2p though.

Most I spent on a servant was a bit over 900 SQ for Castoria, and I didn't get her lol

Skadi over 900SQ over multiple banners from the time she came

For a single copy it's Nero Bride, with exactly 600 sq. But Okita might surpass her soon :D

As a servant in general, it's Tamamo with almost 1200 sq.

Definitly Ibaraki lancer

Her 1st copy cost me around ~1000 SQ on both her summer banners

Right now she's np4 across another 2 Banners with a combined of ~650 SQ

It's sad but i'm really unlucky when it comes to ibarakis...

Edit: thinking about it in the process of summoning for ibaraki lancer I got Jarcher np3, Shuten np3 and Cleopatra np2..

Spishtar, 420sq + 30tics

Sigurd, 1800+ quartz for NP1. Another 300ish for NP2 on a different banner, and less than 200 for the remaining 3 (1 was GSSR, the other 2 were a 3rd banner.)

1200 on summer Abby.🤔

Raikou took me more than 3000 sq to get one measly copy.

Mine would be np1 Yuyu at 1000 SQ...

Hopefully they implement pity early so that this won't happen again (or worse).
