Sitting on Glorious Sigs cuz I only got 1 key
After opening 50ish SBC's and receiving mostly catalysts, I'm now sitting on 55 Glorious Guardian sigs having only received 1 key from the Alliance Banquet event. (Pulled Sentinel)
There's no way I'm going to invest more units into this event, so the only other 2 guaranteed keys are unreachable.
How long will I need to sit on these sigs before the Glorious Guardians reach the regular 7 star pool?
