Righty tighty, to address the question for limits in terms of injury, it should at least be humanly possible for someone to survive from it (Adding on top the special case of the armour and such). From his description it's more like he got knocked out through physical means, which from what I've read from the internet (since I'm no doctor) is okay if it's just a few minutes - more than a few hours and you have serious problems. I can ask my relative about this since he's a nurse so I can confirm realistic injuries, but he's not always available.
In my opinion it should be an easy fix (and as of right now has been fixed I believe).
For the story, I will try to advance it tomorrow, but just so all of you are informed of my situation, expect a slower pace in posting schedule from me. I usually write better in a laptop and I am only borrowing one as of now and I can't guarantee that I will always have this tool on hand. If you find yourselves wanting to post something additional, you have my go ahead and it might give me more ideas for the next post. If you have any questions or concerns, you can come straight to me seeing as my Co-GM is quite buggered down at the moment. I will try to answer through my phone, but I make it a point never to write an IC post with my phone for quality reasons.
