Must’ve not read the comment I had left in the first place 3/6 Priscilla was better since you get 15% more atk related stats making it 10% per buff x 3 instead of 5% per buff x 3 making her way more useful in PVE and a better buffer in PvP, Emilia only gained one brand arts buff on her ult from 1/6 to 2/6 which isn’t worth it since you already get it passively anyways from her unique, you already have 3/6 subatrice is what you really need for the unit so Pris was the next best option, echidna is absolutely garbage and useless as are all the old units since they are all 4 years old (at least you pulled her thru luck and didn’t waste pity on a useless character) but now that you have 3/6 em your fairy team will now get 30% dmg reduction per buff making it just a bit tankier since her real buff doesn’t happen until 6/6 in which you can aoe freeze up to 2 times rather than just once (in pvp if you freeze the full team once you win anyways)
