Working my way thru the Destiny Stone and the Magic Mouth is asking for the 5 words. I've covered this dungeon completely and haven't found clues to the 5. Do I need to revisit other places to get the clues to receive the Dreamspell?
Thanks,

Yep. There are five locations throughout the game that will tell you what words you need. There's one in each of the dungeons before the Destiny Stone, with the exception of The Tombs. There are no clues in the Destiny Stone.

There's also a nice little house, way up in the NE corner of the wilderness that you'll want to visit if you haven't already done so. That will tell you what order to put the words in for the Magic Mouth.

The workshop you need to enter to find the proper order for the words is actually in one of the towns. The workshop in the wilderness is a separate building. it was a while since I had done that part of the quest, so I confused the two.
