How do i start CWK exchange quest?

I've done it 3 times ~_~ DK, Hermit, Paladin. (whatever comes in CWKII I'd like to be ready for)


If you can get the warp rocks from Nautilus to Omega Sector, it helps a ton. Also, I did it while doing my 3rd job advance on the Hermit since I needed to go back and forth anyway.

I only did the exchange on 2 characters, but I did the pendant one on every character I had that was 80+ (6 characters)
