But we have to disillusion ourselves of the ridiculous notion that martial characters have to obey the laws of physics.

With the amount of damage that martial characters can tank or dish out, I think the only explanation is that martials use magic as well, just not the conscious brainy kind. There must be some subconscious muscle magic going on that bends reality in a more subtle and localised way.

“You do not find the trap.” (regardless of actual presence of a trap) if you’re a chaotic DM.
