I’ve been saying for a while now that the skill challenges in D&D4e are a nifty idea that was poorly executed. The “extended challenges” rules are my attempt to fix that, essentially by adapting the Focus System rules from Arianrhod to the rules and general attitude of 4e. The result is a 3-page rules module that in theory should be easy to drop into a game with zero changes to how characters or anything else are handled.
I haven’t had a chance to try it out at all–our last attempt at getting back into 4e fizzled–and there are a few things I didn’t get around to fully fleshing out, but I figured I might as well fling it at the interwebs to see what people make of it.
