The one roll issue I have is the illithid wisdom ones that require you get to 1. That's a failure by the DnD rules. I got a 1 on one of those and passed - why bother rolling at all if there is no chance of failure? I'm not going to get more content if I roll a 20 which is the only reason a DM might try something like that.
Well, it's not forever, you'll have to pay for it with your brain. >D If you use a worm, you already conditionally get more content, but pay for it.
