I posted a homebrew class i made previous so here's another one! GunFu Master, a hybrid class between Monk and Gunslinger. Constructive criticism is welcome!
As currently written, making melee attacks with your firearms imposes a -4 penalty to attack rolls because the gunfu master is not proficient with the cestus, club, quarterstaff, or spear. He is proficient with firearms and nothing else. Can't figure out why. You might as well give him proficiency with simple weapons.
Good to have some free gun-fu mastery out there. ;)
