What are you talking about? With modest (~40s) quality leather armor and the padded shirt thing, you can easily reduce the damage any non-bear (maybe bears, too) does to a tiny fraction of your SHP and the armor itself will take either no or barely any damage.
As a guesstimate, I'd say you can take on non-Mordor beasties fairly easily in the 50 range. The main limiting factor is how quickly they attack - if it takes longer to aim than it does for them to build up the attack bar, you're screwed. Given how they'll be the only ones affecting combat advantage, this usually means you want it to be over in a couple of hits tops.
From what I understand maximum damage is affected by the
lower of the tool and your skill. Perception increases the minimum damage done.
