A lot of people have asked if it is possible to obtain the Viper Armor sold by the old woman during the quest “Open Sesame”. The crafting formulas for the items can be bought from her before the auction begins, but it is possible to start the auction without noticing or purchasing items from her.
Unless you use the Console Commands (PC only), there are no ways to obtain the armor after you have finished this quest. It is a shame that lots of people who wish to craft this armor will have to go back and play again (although the expansion is worth a second playthrough imo).
Any other questions?
If you have any other questions about the expansion or obtaining certain items then comment below! From this expansion then I have learnt that I must go through the next expansion a lot more thoroughly as I missed out on this armor on my first playthrough.
