First off sorry for ALL the text.
Now the problem I face is one of my characters Is a deathwatch space marine (yes I know, stupid mistake but its my first time GMing and seeing as how he was agreeing to give up all his gear and the solo mode etc abilities I at the time agreed to it) and i didn't really have much choice as he was either playing this or nothing at all (trying to keep his number of characters down as he works offshore and misses a lot of games anyway). As a group consisting of close friends who mainly meet up to game, I allowed it. So he is a Dark Angel, working undercover, as a specialist light scout, for some reason or other because reasons.
now the problem I have is that almost no way to hurt him without increasing the power level of the game to frankly ridiculous heights (plasma, plasma everywhere).
I've come up with a theory but thought I would run it by the forums, see what you guys think/ any advice you guys have.
Basically if a gun by passes your Armour it instantly does a minimum of one damage, not a massive change but im trying not to outright murder the other characters who do not have the ridiculous im a space marine hear me roar (and by god the implants!).
So the question is, does this make things more challenging (still nowhere near lethal but at least it can hurt him) without being a huge factor for the normal PC? any other suggestions (other than refusing him the SM which at this point would be a **** move and not what i want to go with) for how to deal with this?
