Rapier:Conventions - Acknowledgement of blows - What is a valid blow

What is a valid blow?

1. In judging blows, you are presumed to be wearing thin clothing, such as unpadded linen, and your opponent's weapon is extremely sharp on point and edge. Any blow that would have penetrated the skin, in your judgment, is valid. Kingdoms are not allowed to alter this standard.
2. Tournaments that change the effects of a valid blow are allowed, such as:
   1. "Armor as worn" tournaments, in which certain types of armor can be considered to be resistant to specific types of blows for the purposes of scoring.
   2. Tournaments with differing victory conditions (for example, "only head shots count").
