Thanks for getting back to me so soon on my Changeling question. As this would be a plot reward, I'm going to go with Winter Masques rules as far as when it can be taken, but the information in Rites of Spring was very helpful.

I still have one question- since Rites of Spring says that the character only gets blessing and curse from primary seeming, I assume that means that they only get the contract discount for primary seeming as well? I.E. the Gravewright character who's looking to pick up Brewer would get the Darkness contracts at discount, but not the Artifice ones- correct?

More generally- what about the small handful of contracts in Rites of Spring that are affinity for two seemings- how would you have this work if one of the seemings on the affinity list was the seeming providing the "secondary" kith?
