Just curious about this one. CR recommends that Deception checks be opposed by either Vigilance (p24) or Discipline (p113), presumably depending on circumstances.
I was just wondering what GMs do when PCs try to tell a very implausible lie. Do you:
a) Do an opposed check.
b) Do an opposed check but add lots of Setbacks.
c) Do an opposed check but upgrade the difficulty.
d) Do an opposed check but increase the difficulty.
e) Just say "it's a ridiculous lie, so that's going to be a Daunting check with 2 upgrades", or whatever difficulty you make up.
RAW suggests it should probably be a) or b), but I suspect that e) is just much easier all round. Wondered whether this was something anyone else has thought about at all?
