I read this on the http://www.uesp.net/wiki/Skyrim:Atronach_Forge site today:

"A decent amount of profit can be made by creating dremora with the forge. The dremora will always carry an enchanted weapon and a daedra heart. You need only one daedra heart and an excess of raw meat and skulls to create numerous enchanted weapons."

Since summoning an unbound dremora from the Atronach Forge requires a sigil stone, does this mean that I can get more than one or two (the http://elderscrolls.wikia.com/wiki/Sigil_Stone_(Skyrim) site explains an exploit to get an extra stone)? To me, "create numerous enchanted weapons" in the same sentence as summoning dremora means that I might be able to get another stone. Can I cast the ritual spell multiple times and force the dremora to fetch me a stone?

Thanks for the help!

I think this should be moved to the Hints, Cheats, and Spoilers forum. Sorry.

You keep the stone after the conjuration ritual quest is over, and the stone is placed in a special holder on the altar not in the box.

Awesome. So, the Atronach Forge does not consume the stone like the rest of the ingredients?

Yes.

Thanks for the help.
