Vampiress X-MAS Set

The X-MAS Set can be found for all character classes and for most classes they appear to be almost the same though I am not 100% sure on this. These items seem to be found at random locations just laying on the ground but only around Christmas time.  Most people say you can only find them in Multi-player but there are rumors that Aducar will drop them on occasion in Single Player. Almost all the current info. on these items is pure guesswork at this point so it is hard to tell you exactly what the deal is... if anyone knows anymore please let me know.  (Big thanks to Throend's post on the German forum I think it was for all the screenies)...
