Swim Speed

[blzbob]

I'm trying to add an alchemist discovery.

"Amphibious Mutagen: Whenever the alchemist imbibes a mutagen, he gains a natural swim rate equal to his base move rate, and he gains the ability to breathe naturally underwater.'

How do I get it to add a swim speed equal to the base speed of the creature?

I looked at the Amphibious templates but they look like they are more complicated than I'm trying to do.

Check out the Shaman's Fluid Mastery ability for an example of that.

Thanks! There's so many different abilities that I easily forget where to find examples of some of the more obscure ones.
