After over a decade of bringing you the latest Diablo news and builds, DiabloFans will be shutting down on March 21st, 2019. On this date, we will archive the site in an effort to preserve the history. Thanks for your patronage throughout the years.
How can we know where are your items ? Try to be more specific with a question.
I'm assuming you are asking about item vendor on ptr servers - in that case i don't think there is a vendor with set items other than necro. Vendors only got bag of items that were changed in the patch, but only non set items like blessed shield weapon and shield etc. If you didnt have this set somewhere in your vault, you will need to farm for it normal way im affraid.
