Your mama is a poodle…So Fafhrd could go up to a line of Buckingham palace guards and incite them to violence with just a few words in a moment? Without showing an immediate threat or touching them? A conclave of wizards would forego all spells and walk up to Fafhrd and engage in fisticuffs instead of just turning him into a toad? They can insult a pack of wolves by telling them their mother was a poodle?
But yes, I do judge what a person can do without magic with at least a baseline in reality. It may likely be feats of strength or skill that is not possible in our world, but it will just be an extension of what a real person could do if they were fast, strong, tough or skilled enough. It's the difference between watching the latest James Bond or even a Fast and Furious movie versus Harry Potter.
It's also just a preference that I have an option to play a mundane character. Even if that "mundane" character does things only Captain America could do.
what you are saying is that ignoring context would be supernatural.
I am thinking some powers like compelled duel etc. allow you to supersede context—-which is the province of magic.
