In terms of rolling, I had gotten *five* gold servants who were not on rate up, three of them being assassins, all from Waver's banner. Those being Kiritsugu NP2, Chiyome NP1, d'Eon NP2, Carmilla NP4, and Suzuka NP2. The d'Eon and Carmilla copies were turned into bond grail money for my other servants, mostly because my d'Eon is nearly Bond 10 now and I've not even once used their NP so I don't foresee the upgrade ever being worthwhile. They ARE an amazing tank though and I can't stress that fact enough. And Carmilla is strong enough as she is at NP3, it's hard to justify bringing her out anyways when I have two different grailed assassins.
I've exhausted my entire supply of quartz and tickets and Waver only came yesterday at the very end of it all (including 30 quartz from Skadi hitting bond 11 and 30 quartz from 50 logins reward, and several chunks of 2 and 3 quartz from assorted bond levels). He was a silver caster and I was already standing up from my PC and clicked to skip it while heading away, then I had done possibly the biggest double take in my life when this joker decided to flash gold and show up after I'd already given up.
As for the raid itself... I'm eating enough apples to get as many Void Dusts as I need to max out Waver's skills, then I'm gonna chill and only use natural AP for the rest of it. I had only previously budgeted enough dusts for Gray, and she left me with no void sugar for Waver's void coffee.
Also Gray is precious and must be protected at all costs
