Slam (Ex)
"An eidolon can deliver a devastating slam attack. This attack is a primary attack. The slam deals 1d8 points of damage (2d6 if Large, 2d8 if Huge). The eidolon must have the limbs (arms) evolution to take this evolution. Alternatively, the eidolon can replace the claws from its base form with this slam attack (this still costs 1 evolution point). This evolution can be selected more than once, but the eidolon must possess an equal number of the limbs evolution."
By it saying "alternatively" and "can" can I assume that my eidolon could have 2 claws and slam? I personally don't see why not. It would also go for the 3 max attacks at level one. Claw, claw, slam. Same question goes for pincers and slam.
