Gretchen are the luckiest beings in the 40K universe. Whenever you shoot at other units you get normal odds, but fate intervenes to save the humble grot. Even if you dont roll a one to hit, you are still likely to fail to wound, the more powerful the weapon the more likely you are to roll ones.
Is this some form of psychic shield, is there some force protecting the underdogs of the galaxy. I know I am not alone in observing this phenomena, but perhaps elsewhere its something else that receives the 'Shield of Ones'.
Please post your experiences, excepting individual 'one-offs' (no pun intended).
