Xarza's now has an Archon Level limit to get in, unsure what level you need to be to enter but low 70's was too low.
Entry to Curse of Xazra is NO LONGER DONE by placing any random item inside the scatter item container "a battered wooden chest"
Instead, archons will forcibly enter by unlocking the chest, then opening the chest while it is out of your inventory. Upon opening the chest, you will be immediately teleported into the Curse of Xazra, and stuck there until you find the exit. WARNING: do not wear anything you are not 100% prepared to lose. Only ONE person may go at a time. The chest will disappear immediately after one person opens it.
Upon opening the chest, a Xazra mob will be released out into the game to a random location. It will tell you which mob has escaped. See below.
