I have cleared the lower part of the tower, this was after climping to the top and using the stone. I fought the ghost and my way out of the lower part of the tower. Still haven't found Lord Lovis or how I get into the tower. Any help would be great. I have clear most of the valley.

The lower part of the tower is meant for another side quest Do you open all the locked gate on the way to the top of tower ???

How do I get out of the lower part of lovis tower?

You have to look into the stone you get from hitting the switch upstairs in the fire room. If you do it before you give the stone to the priest guy back in the village you still complete the quest it just saves a trip (sort of).

I have all the gates open, I have been in the top, all chains pulled, used stone, in second room (after opening all gates) cleared basement, went back up to room where I used stone got trapped. I have found a guide that talks about a "Reveal Spell", maybe on computer, can't find on xbox 360. Running out of things to do without clearing this tower.

I looked into the stone that's where I'm trapped at now. I killed the ghost and everhthing else in the celler or whereever it is but know I can't figure out how to get out the exit doesn't work.

You have to use 2 fireplace (or whatever it call) which have green fire on it. 2 platforms will appear , and now it up to you
