A fall is an uncontrolled descent, landing pretty much by chance. Characters cannot fall on purpose, but only as a result of an accident or being pushed.
To determine whether a fall causes damage, first decide the distance jumped in yards, rounding up to the nearest full yard and doubling the result.
Now roll a D6 and deduct the score from the distance fallen. If the result is zero or less, no damage is sustained. If the score is positive, then the character loses that many W - irrespective of armour or T modifiers. Characters with Acrobatics skill should add +2 to the die roll.
A character taking W damage from a fall will drop anything held in their hands 50% of the time.
