Those items as a set apparently were too powerful to be left in game and were removed. As for serenstum, i have that recipe on 6 toons and able to craft them, but that is runewaker programming for you. Anything that is good and you really want, well, they remove it and let you rage about it. Sadly i never understood Gameforge resentment towards the players to have the items that are in game and should always be there and never removed, look at Laor forest tart = 6 seconds physical immunity !!!! oh no, you can't have that!!! SAID ALL THE ROGUES BACK IN THE DAY!!! but serenstum was ok for them to have, to play against magic classes tho!!! hahahaha
