First off Id like to say that I am very new to Pathfinder and while I do know how to play D&D I have not had a chance to play it very much. I currently have an Eidolon with Claws x2 (1d6+3 with improved damage), Bite (1d8+4 feat Improved natural attack), and Slam (2d6+3 improved damage).
I have looked over the rules for found here http://www.d20pfsrd.com/bestiary/rules-for-monsters/universal-monster-rules #TOC-Natural-Attacks. And I still am not sure if at any point I can use all 4 of those primary attacks (claws count as 2 I believe) in one 6 second round of combat. The rules on natural attacks are not clear enough for me to convince my DM and other party members that my Eidolon can indeed make those attacks all at once. I believe this due to the multiple places where I've read that you can do that. I have discovered that I may have to take a Full Round Action to do what I am thinking. Which is roll a d20 4 times (one for each attack) and then roll damage on each if they hit.
I simply need to know if this is true, and how exactly this works. I ask because my DM and the other players wont take anything but something crystal clear. Probably because Im new and can't seem to explain myself properly. Thank you for any help you can give me. :)
