Need heaven's key! Have very few things to trade!

I could really use a heaven's key! I'm trying to farm offline Ur Dragon quickly, but I need a heaven's key to do so. I'd like to use the augment that boosts strength when soloing, on top of the night time augments and warrior augments, but at the moment I require my pawn to buff my weapons with holy. If I could get heaven's keys, I wouldn't need him, and would do even more damage! So, if anyone has an extra, or if anyone wants to trade for carnation and/or ascalon, hit me up on xbox live! Gamertag is tehtonym, pawn is Dybbuk/Zilah.
