I love harping on you guys about the specifics of encounter design under "WTF 400 PEOPLE I CAN'T MOVE" circumstances, but it occurs to me that I don't really know what goes into it. Do you start with an existing creature as a base and then pump up the stats, or do you build something from scratch? How difficult is to graft additional powers onto something? Are there any powers you wish an event monster could use, but which can't be added for some reason? If you can talk about this, what's the UI overhead like? What I mean is, if you wanted to take a Dark Father and give it Serrado's poison AOE effect, would you just be checking off a box, or would this be an involved process? Just curious.
