MoMF and necklace of natural weapons pricing

[Venger]

How do I calculate pricing for a necklace of natural weapons if I am a MoMF and my number of natural attacks constantly changes? one day I may be a trex with 1 attack, another I may be a rukanyr with many attacks. what do?

The necklace is built to affect a certain number of attacks and priced accordingly; that number doesn't change just because your current form doesn't match it. If you have a necklace that improves 3 attacks, it improves 3 attacks regardless of how many attacks you have available while wearing it. If your number of natural weapons exceeds the number the necklace is built for you'll just have to deal with having some of your attacks not benefit from it.
