I just looked at the preview on RPGNow, and absolutely love the bearowl and goblin-o-wisp, especially since my guys are in the middle of Chapter 2 in Kingmaker!!! When will this be available at Paizo?
I uploaded it to Paizo. As soon as they approve it and put it up, it will be up. Liz (the one that does that) is out this week so it might not be up this week.
