Re: [3.5] Arrow DMG type Slashing/Piercing
The PHB2 errata answers this question. You can probably find the errata pdf on google, but ultimately, it specifies that Melee and Ranged Weapon Mastery feats don't offer a benefit for each type of damage that the weapon deals. With a Morningstar, for example, you'd still only gain +2/+2.
EDIT: Misread the question. I don't think you can take the feat twice but let me check the errata.
Okay, so per the official errata, here's the answer:
On Melee Weapon Mastery:
Add the following the two following sentence to
the end of the “Benefit” section: “Weapons with
two damage types (such as the morningstar, which
does bludgeoning and piercing damage) the
benefits of Melee Weapon Mastery (bludgeoning)
and Melee Weapon Mastery (piercing) do not stack.
But the bonuses from this feat do stack with those
gained from Weapon Focus and Weapon
On Ranged Weapon Mastery:
Add the following text to the end of the “Benefit”
section: The bonuses from this feat do stack with
those gained from Weapon Focus and Weapon
So while it's probably RAI that RWM should function as with MWM above, the errata doesn't specify as such. The default rule here then, is whether or not untyped bonuses from the sources with the same name stack or not...and they don't. There's an argument to be made that the damage is not from the same source (+2/+2 Piercing and +2/+2 Slashing) but, the fact is that Slashing and Piercing are just selected pre-requisites.
Mechanically, what you're getting is (+2/+2 untyped when using a weapon of the selected type) and in both cases it'd be from a source with the same name, ergo, by RAW, this doesn't work.
Would it hurt to rule that the opposite is true? Probably not. As said, Archery needs all the help it can get.
