In epic scaled games, I work around this with a “reroll at -20”. So the rogue in this case would have had about a 25% chance to recover on a DC10 check.

I also always include an in-game explanation. In this case, I would have made it a huge flashy “boon of insight” from the Paladin’s deity.

Then it’s all the more fun if the rogue actually manages the re-roll. “Dude, I even tricked your god!”

I would also RP right into it. “A voice from on high intones ‘I dunno, seems legit, to me.’”

Similarly if the rogue actually fails:

“A voice from on high intones ‘Seriously, you need to stop falling for this crap. I’m going to send you an amulet of insight or something. What’s your next stop?’”
