I'm gonna keep voting Bugbears until those oversize weapons are out of my sight.
I think the kernel of the idea came from the durzagon, a late 3.5e monster which was basically a duergar crossed with a bearded devil. The bearded devil part of their ancestry gave them a spiky beard. In 4e, it seems that all duergar have bearded devil ancestry, and the spikes can appear in hair as well as beards.This time I voted for Duergar. Dwarves who shoot poisonous quills out of their heads? Wth is that?
I'm sorry to see the dislike for Kenku - I think that they are one of the cooler monster races. Ah well, I liked Drow as well, likely because I somehow hadn't even heard of Drist until about a year ago.
