Chiron is support Archer similar to Tristan, he is like Nero Bride for critical-based team. Excellent DPS that have no qualms to take support role.

Valkyrie and Parvati are, can be considered optional as, Valkyrie is all-purpose unit (have nothing to excels on) which have weak priority if you have SSR Lancer while Parvati is strong farmer with Skadi available to keep her NP running which you migh consider for Archer nodes / boss.

Cas Gil NP 5 is precious for reason I don't need to said.

Kiritsugu is good. Thanks to recent increase on critical support, his value is far better than during his debut. Have no qualms providing unique support with his kit.

Gorgon is optional. The main reason why you pick her would be because you want Avenger to deal with Ruler. Her value is weak aside of waifu reason if you already have another Avenger that's not Salieri, especially SSR ones like Dantes or J. Alter.
