I've set on Medb for a very long time. On the lists of the servants that I lost, when it comes to non-limited servants she's the hardest one to get, considering I wouldn't roll on story gacha.

Easy Tamamo pick.

That said, Sitonai would be a secondary choice, as I do need a new Alter Ego because I just finished up with my other ST ones.

If I was going to NP2 something though, probably Brad in order to be contrarian.

Sitonai is worth it Wary, used her on my alt often enough, looking forward to the lotto to actually level her skills up. Just keep in mind she is ST more for boss fights rather than AoE like those two.

Tamamo isn't bad, but she is more for a plug suit extra buff when you have Caster Artoria. There is also the fact that she may one day spook you no matter what banner you are on, which Sitonai can't do, Story Banner or Rate Up only for her.

Anyway, for my own choices, while I admit making Vlad stronger would be useful, I'm going for missing story locks myself. My primary is still missing Cu Alter, Medb and Quetz of the story locks. The main account will get Medb, because costumes (even though I only have one, is her Warden costume ever made free to claim or will I need a bunch of RP?) and most missions available on her, while the alt gets Cu Alter for the most extra Quartz.

I know it is there, but requires 5 RPs. I know some costumes there like the above Gym Uniform for Nero are either free in an upcoming event or are made free to claim once you have enough progress in the game. No sure if the Warden costume does so.

I think it's going to be Vlad. I've loved his character since Apocrypha (and tried to roll for him on the Apocrypha banner and got Vlad Extra instead, ha, ha!), and he appears to be best choice for the Arts focus that has been at the forefront since I started playing. He'll go to 10/10/10 immediately.

This forthcoming battle with Cernunnos has me rather concerned and I have somewhat considered going with Enkidu largely because of that. However, I think I'll regret it if I do choose him (and I don't think he can immediately go to 10/10/10).

I will take Drake since she is the last servant unsummoned.

This is my current pool. I was thinking getting Vlad since I already have a decent Arts setup and he's ST. Waver and Tamamo of course are top tier options but I am rolling for Oberon now and Lady Avalon next year so they're not that appetizing to me.

Tesla for a future Buster system could work too(Not Koyan for now, I'll wait till January) but my boy Cú is NP4 so he should be able to do the job.

I wanted to go for Mante, but since Old Man Li is the only one, who cannot spook me - even if chances of getting the others are astronomically low at this point - I will switch to him.

Sitonai for me, story locked, good and cute :3
