I imagine it would be like being in the game, damage hurts, but I mean in graal the character grimaces and is "hit" for a second and then okay. No blood, trauma, bleeding, physical effects, it's like you are still perfectly okay. You can be blown up and get back up good as new.
Obviously it would still hurt, but not as much.. Almost like you just got hit in that area of your body, I guess.
I mean, it would be like in graal, living life on the screen..
