Got a Humanoid Stone off a Kun Lai Runt when I was trying to capture one of them tonight, made it easy to upgrade my uncommon to rare. Only time I've seen a stone drop outside of bags. Still haven't seen a universal stone, just Magic, Dragon, Humanoid, and Beast stones so far for me.

Just grabbed Cinder Kitten in the Blizzard Store, stumbled in there checking to see if the mounts were on sale for US, and it was the first thing listed...already have my redemption codes, checking to see if servers are live now.
