Ooooh, Zone of Truth ! I've had so much fun with that one 😁 It's amazing how much you can say that's totally mis-directing with out actually telling a lie. Or you can just answer questions utterly literally while not volunteering any extra information whatsoever. Like, information that's going to be essential later but they just didn't know to ask for it.
Although one of the best fun ones was when a party asked a guard the right questions, and he rolled a natural 1 on his will save. He opened his mouth and everything came out. So much useful info that they just didn't know what to do with it all !
@alonicus yes! Zone of truth is awesome and you can do a lot of things with it. You'll see in the next chapter, we use it differently than we intended, but it's still fun.
