I know you've already figured this one out for yourself, but it seems like you were asking for a general hint on how to beat the room. This is the Challenges forum...the Hints and Solutions forum is
here. When you make a new topic there you get a map that shows you all the levels and rooms so you can choose what you need help with (once you choose the correct hold--you're on King Dugan's Dungeon), and then the forum shows all the previously created topics on that same exact room, so you can see other people's hint requests and the answers to them. And of course if those don't help then you can always ask for yourself there.
Game on,
