Those are two interesting options, Ranger REG.
Right now, I'm thinking of Crouching Tiger, Hidden Dragon (and other martial arts movies). I have no idea how to spell the names of the characters, but the main ones that do most of the fighting seem to rely on a lot of weapons (the Green Destiny, for starters).
Seems to me that these are monks... Maybe monk/rogues. Either way, it seems that despite their amazing mastery of unarmed strikes (martial arts), they like to use weapons just as much, if not more. That being the case, it seems the characters believe that the weapons are as effective, if not more effective, than their unarmed strikes.
I'm thinking there should be something in DnD that's similar.
If a rogue can add their sneak attack damage, in certain situations, it seems that there ought to be a rule that monks could take advatage of to substitute their unarmed damage for the damage dealt by a weapon they're wielding...
Arcana Evolved has a class called the Oathsworn that is very similar to the monk. One of the class abilities allows an oathsword to throw any object and apply unarmed damage (similar to monk's) instead of what the object would cause as a thrown weapon.
Is there a prestige class that has such an ability with melee monk weapons?
