Seriously, most parties crawl through these dungeons at like 5 feet per minute thanks to the take 20 rules. I think the rogue should get a verisilimitude XP bonus for acting in a realistic fashion by taking a quick look instead of getting out the magnifying glass and examining every nook and cranny of the potentially trapped object.
You ARE taking the piss here, right?
"Hi. I'm an adventurer. I go looking for trouble. Often, I will come across something that I think may possibly KILL me if I touch it. However it would be silly of me to spend 2 minutes to ensure my safety, so often I just glance at it for 6 seconds and assume that I must have seen anything that is there".
I'm sorry, but I can't imagine spending less than about 2 minutes in each room of a ruin that I'm exploring for the first time.
I certainly can't imagine walking through each room in less than 6 seconds unless I know where I'm going and I'm in a hurry.
And I most certainly am not touching anything without first thoroughly examining it.
And I'm not even talking about a place that I KNOW to be full of monsters and traps. I'm talking about an old mineshaft or the like.
But I also agree that he should take 3d6 damage for putting his hand on a live metal object. I encourage any of you to try it and see how many times out of 20 you don't get shocked.
Actually that would be "how many times do you get shocked a little bit, and how many times do you die".
People survive minor contact with electricals quite often. You could put that down to hitpoints and low damage rolls, or you could put it down to reflex saves.
