Beastmasters and Martial Artists(not the archetypes)

[Tela]

I'm basically curious as to if this would work. My friend says no, but I tend to over-think and/or under-think things so... yeah...

Thing is, both the Beastmaster class and the Martial Artist class have the ability Fast Movement. The wording on both say the same as that for a barbarian, exluding the obvious class name changes and an add on that reads "However, it [Fast Movement] does not stack with the identical Barbarian ability."

Now in my mind, it said it did not stack with the barbarian's identical ability -- not about an identical ability in general. So while a Barbarian/Beastmaster or Barbarian/Martial Artist would not get a 50ft base speed, a Beastmaster/Martial Artist would.

Am I correct or would it just increase to a 40ft base speed? In case it matters at all, both classes were made by the same company.

Since the ability has the same name and is worded nearly identically, I would rule it does not stack.

For the best answer I would contact the folks over at TripodMachine. They could give you an official ruling but I'm inclined to agree with Rite Publishing. I'd probably rule that they do not stack.
