The idea to use Vira is not my own. A video of an interesting solo attempt was shared in my guild's Discord and I wanted to try my own hand at it. It seems like the original user's name is Reverie, so please check out their channel because frankly they deserve all the credit. https://www.youtube.com/@echostringrites
I'm not too sure about the luck factor yet. The main source of RNG in this setup is landing Vira's Divine Jail below 20% multiple times while Faa builds up a stacking debuff resistance towards it. I don't understand the math behind it and I can't seem to find any resource explaining it so if you're an expert on the subject, please tell me. I've tried to mitigate against this RNG with debuff success EMPs, ring, artifact, and Bubs call and I ended up being fortunate enough to land 8 Divine Jails here. Honestly, I have a feeling the stability of the setup might be surprisingly decent if you practice it well enough. In my experience, the first 4 Divine Jails will always land with a Bubs debuff on, and even though I was quite lucky, I was holding onto a FC and 000 in case any of them missed.
I may make a more detailed explanation video, I'm not sure. Thanks for watching.
