Hi dalia! I tried the rattle bones master challenge and got ultra snow apples. Eventually it became an elder and i harvested it and got good rewards, and one snow apple seed. I also got a robe that would look good on me if my ice wasn't lvl 72 and my balance wasn't lvl 26 and so on :(. I also got the meowiarty archmage challenge on malistaire and i accidentally soloed it and it's gone . I have an exalted challenge but i am currently waiting to become an exalted. I would like to rematch the evil jade oni.
rattle bones is the one i have done the most because friends ask me to help them with that one. Wish there was a new world to be exploring and a new story to play instead of just additions of things to farm. I do not want to see a return of Morganthe in any form she defeated herself. The lesson learned from her is that too much power leads to self destruction and destruction of others along the way. As to rematches with bosses defeated in lower level worlds how about making them be apart of a new world with a new story. Although I would rather have a new world and new bosses and new stories to challenge my wizards.
Having done all four of the Exalted dungeons, I have to say that they are all pretty much as enjoyable as each other; in terms of difficulty however, I'll order them:
Zeus (Everyone dies every time, period)
Meowiarty (Everyone dies most of the time)
Rattlebones (A few people die sometimes)
Krokopatra (Someone dies if unlucky, or poor team)
