...And now you had to remind me that Chloe is the first and only Servant to get an upgrade that doesn't do anything to her, only to another Servant, and it's not even an upgrade that helps Illya that much when you could just use Miyu's NP charge skill for example.
And speaking of Chloe, not only she didn't get any upgrade, but they still haven't made her available for players that missed the original and the rerun event. Which really sucks when she's actually quite good for your first 4* Archer.
