[Flashlight237]

So, you know the feat from King Arthur where he pulled a sword wedged into a rock, or the feat in Anya's page of her pulling a knitting needle out of a ship's deck in the Lifting Strength section of her profile? I gotta ask... Is there a way to determine lifting Strength for feats of that type?

Frictional force between the object and whatever it's lodged in, perhaps?
