Hi. Was building a Prowler at World's End today and ran into an odd question. I was planning on going for a natural-attack based build using magic items to stack extra attacks onto my round (helm of the mammoth lord, boots of the raptor, cloak of tentacles, etc) and wondered if the attacks that these items grant carry over after I hit level 11 and can polymorph myself into a cat with beast shape IV. There's a boatload of questions regarding natural attacks but I couldn't find this one specifically when I checked, so sorry if this is something that has come up before.
Thoughts?
