You basically use a custom launcher that disables telemetry and has none of those kernel-level anti-cheat measures and then the game runs smoothly using Proton. This means that you're breaking their TOS though and that at any moment Hoyoverse can ban you if they want. If that's okay for you, google an anime game launcher.
Anyone figured out how to take advantage of the Ousia blocks in the new Verdict of Blades event? I feel like nothing changes when I hit the robots with them.
I feel the same with trying Ousia/Pneuma vs whatever mobs on the map or domain honestly. The only time where I actually noticed it making a useful difference is the Coppelia/Coppelius boss fight. Idk if my characters are generally too strong for however much difference this mechanic is supposed to make however I'm actually happy about it currently not having a massive impact.
