This dungeon is no longer required to enter Celestia. It is only a side quest. It is not impossible to defeat. There are plenty of helpful guides on wizard101central.com to assist you.

Unless players are lucky enough to find a life wizard to battle with you the warehouse quest is extremly difficult. Last night when I was in the warehouse ,started with four, one left second floor another died on the fifth floor so me and one guy tried , hired henchman and used minion, total stress .You don't want to get all the way to the top out of health and get cheated on over and over with no chance to win . Need to balance it out ,it is also to dang long. I felt like a was part of the chair I had sat so long. Please adjust the bosses.
