Ever since 9/18, Xûr has been coming to the tower with something called a Legacy engram. These engrams cost an absurd 31 strange coins. Why? This is because they're meant for players who haven't completed their year 1 weapon collections. If you already completed your collection and are trying to complete your year 2 collection, [b]don't[/b] buy the legacy engrams since they will decrypt at year 1 levels. This is a quote from the 9/17 Weekly Update [quote][b]Lastly, Xûr will also choose a Legacy Engram every week. These Engrams contain Year One Exotics (at Year One Attack and Defense levels) for players who want to finish up a Collection.[/b] They strongly bias towards Exotics not already in your Blueprint Collection, to help fill in the blank slots - excluding Mythoclast and Necrochasm, which are still only available from their Year One sources.[/quote]
