Hmmm, so if a level 40 kensai with +13 to his damage rolls, quaffs a potion of storm giant STR to get an additional +12 damage, causes a critical hit to a Goblin with 7HP, the goblin will simply lay there and happily wake up after a few rounds despite having suffered 52-54 damage? That's pretty amusing. Contrast this to mage with 5 STR killing a goblin with a single poke from an unenchanted dagger.
I've always known that fists are non-lethal, but I was under the impression that once wearing the gauntlets of crushing, opponents could indeed be killed by bare fist fighting. I'm at work at the moment so I can't check this out, but it might be worth investigating.
