PGR Global: Crimson Weave Gacha Pull with 4* Weapon run

Disclaimer: Both Signature Weapon & CUB have been pulled separately outside the video
It's a running joke in my guild we've talked how strong CW is just with the 4 star weapon itself. I'm not an expert in running a no-hit run or no-dmg run so this video is bad.
But hey, at least if you can't get her signature or even the 5* weapon, the 4* is more than sufficient!
