Some weapons are built for the purpose of piercing armor, such as powerful cannons or a rifle. In the olden days, weapons like the arbalest were considered 'dishonorable', because with it, even a peasant untrained for war could take down an armored knight. However, when it comes to armor and piercing it, D&D has always been rather sketchy on the execution. As a result, many of such attacks or powers are channeled as a touch attack, which is a simple but unelegant solution to the problem. In this section I attempt to describe a way to implement an armor piercing factor to certain weapons without sacrificing much of the simplicity you would desire from D&D.
