I just wanted to point-out Beebo's list of horror techniques, which can provide creative inspiration on those days when you're not in a suitably horrific frame of mind for a game. Add a few techniques of your own for a nice d20 list.
(I haven't been posting much lately for three reasons. Things are busy at work, my local D&D group hasn't been active, and I've discovered Minecraft. I'm still reading other D&D blogs and commenting occasionally. Regular posting will resume when I'm less busy and playing regularly. Anybody looking for a player in a PBP or pick-up chat game?)
