“I’m gona punch this fire out!” - my friend… my stupid, stupid friend.
Read the above quote. Think about it. REALLY think about it. Ok, now read this next one.
“I’m gona punch out this metal gun while it spits molten lead in my face and knowing full well that it will explode if I win!” - Not really a quote so much as an idea… a bad, bad idea.
As you can guess I rate this idea even farther below the first. Why? Because you have thought about it (are can type so you are non drunk enough to excuse yourself) and still think punching a gun is a smart choice.
As for an unarmored skill I have to vote no. That is why we have dodge. No manor of training lets you block bullets with your face without armor, heavy mutations and or magic. We have armor, we have mutation, I don’t think we have magic.
Some of this might come off a little strong, sarcasm doesn’t carry well through text, but such is the internet.
Oh, and before I forget. Your unarmed skill DOES increase your defences with martial arts. Block and Leg Block reduse damage and move it to your arms and legs respectively (whatever limb has the most health at the time) and away from lethal areas like the face and chest.
