Hey, everyone!
I have some good news about Chiltara for those of you who've had a tough time finding her as of late. In a future patch, we’re going to increase the chance that she’ll spawn in the Caverns of Frost. Our intention with this change is to make it a bit easier for players to construct a Staff of Herding, but still keep the Gibbering Gemstone as the most difficult component to find:
http://us.battle.net/d3/en/forum/topic/11883998315#2 Note that this change will only increase her spawn chance. The drop rates for the Gibbering Gemstone itself (as well as the Urn of Quickening, and Frozen Blood) will remain the same.
