It's impossible to complete the vault of glass with one or more people as liabilities I know this for fact since for 2 days straight we have attempted and that Liability is what caused the death of us 99.9% of the time. Best attempted when around 26+ better chances when level 28+ but even at that level it still requires the players skill to be skillful and not dreadful.

LMAO. There is no "carrying" through that mission. trust me.
