My experience was one to remember for me. It was in a random encounter of bandits (which aren't too much trouble later in the game and at this point it was MUCH later) and one of the bandits came at me with a spear. Keep in mind I am wearing brotherhood armor; the raider attacks me once and i was sent sliding almost across the entire map. When I saw the message window it said that I was critically hit for and outrageously large number. I was just sat there for a good 5 minutes before realizing what happen; I don't remember every laughing and crying so hard (my last save wasn't too recent).
