Rastus the Animal (A female human) been running around killing things for a while, had racked up approx 100 kills and was about as capable a fighter as any adventurer I've ever produced (I'm more a fortress person, really). I'd massacred my town of origin, mostly at night, but had successfully killed off about 20 or so remaining citizens in open combat, sustaining only a single scratch to the left hand. Arrows and Axe blows had bounced off me without the slightest worry and I slaughtered all who approached. I decided to sneak into a new human town one evening and kill every fighter in their sleep, leaving only sweet soft unarmoured/unskilled civilians who would mob me come daytime, with the idea that since they were all soft and weaponless, they'd be fine.
Step 1 went down quite smoothly, anyone whos bronze armour deflected my scimitar's blows was simply strangled and soon the town was without defenders. I stopped sneaking around and let the sun rise. Two children came out of their homes and were both killed with a single swing to the lower body, splitting them in half. Still, things were going smoothly for this inhuman merchant of death, in fact, things were going slowly, if anything.
During my purging of the town's warriors, I had not noticed a priestess, who carried an Axe. Chances are, I'd have not worried about her regardless, as she wore only robes. After dispatching the two children, I saw her coming out of her home. I carelessly wandered over to her and moved to attack. She charged and ran past me. I didn't think too much of it and came back at her.
All of a sudden, my page was filled with notices about deflected blows. I was lying on the ground and she was wailing on me. My legendary fighter/wrestler managed to hurl herself at the superhuman priest once in the entire fight with the blow being deflected.
So, I guess my stupid action was to try and pick a fight with an entire town and not work on the basis that there may be someone in there who's better skilled than my barely legendary adventurer. Probably should have beat up more children first or something.
