I am trying to get the dead winds and I'm stuck in the Crypt Tower on the first floor. I smashed all the crypts and destroyed all the Disturbed. Now I cannot get through the door to the second level. It says that I need a key. Does anyone know where I may find the key to the second level of the Crypt tower?

The key is in one of the sarcophaguses. If you smashed them all, you'll have some baggy-searching to do.
