1) to find Cassandras bones in the temple of the dead throw one of the teleportation pyramids down on the sacrificial plate (where the dead animals was) and pull the leaver. You can now use the other portal to go find her bones.
Bonus hint: you can use teh same spell you use to make DK's vulnerable to make the sentinels vulnerable
2) Im stuck at the ascension quest as well. can't get trough the earth or air door.. I can see the earth door key, but can't figure out how to get to it or progress..
