Weapon-Specific Feats

Martial weapons are not for everyone. A commoner would have no idea how to even grab a rapier. A farmer might understand how to grab an axe, but would have no combat experience with it, being unable to use it for the most gruesome outcome. These feats intent to show how a martial combatant can attain mastery in a particular weapon and excel at fighting with it.

Specializing your character The purpose of these feats is specializing a PC so that they are more inclined to use a single type of weapon, effectively reflection a lifetime of practice or otherwise other circunstances that make a character excel with a particular weapon or weapon set. Most of the feats apply to a particular set of weapons, like Swords, Axes or Bludgenion weapons. A few weapons get specific feats, like blowguns, rapiers and scimitars. I decided to make feats only for Martial weapons, as the intent is to reflect the skill someone has attained with particular weapons, that puts them apart other people that simply feel "confortable" using them, but haven't completely mastered them. Simple weapons would feel odd here, in my opinion. I did leave out some Martial weapons, particularly those affected by other feats on the PHB. These are Crossbows, and the weapons affected by Polearm Master feat.
