The Single-Handed Broadsword is the single handed cruciform sword of the High Middle Ages, in common use between 1000 and 1350 and possibly even down to the 16th century. It is a common weapon in period artwork. The sword was worn by a knight even when not in armor and he would be considered 'undressed' for public if he were without it.
If your opponent played a Power Blow last turn, you may play an additional attack. You take one damage when you block a Power Blow with a Power Block.
