Swamp's Grasp is exactly what I wanted to use. Unfortunately I already played my Skinwalker at level 2, assuming these features were illegal. Maybe I will retrain my classes, or just hope to obtain another copy of the boon.

Edit: Oh dang, I guess retraining wouldn't really be feasible: I forgot I chose a weretiger-kin. And by the time I get 20 prestige to change to a werecrocodile-kin and 14 to retrain the class levels, I'm not sure it will be worth it. And that's assuming I can even retrain the heritage, which I really don't think I can anyway.

Additional Resources has this to say about Blood of the Moon (bolding mine):

To create a skinwalker (which includes all were-kin), you must have a Chronicle sheet that opens the race as a legal option at character creation.

Note: Racial feats, racial traits, and racial spells are only available for characters of the skinwalker race. Racial equipment and magic items can be purchased and used by any race as long as the specific item permits it.

The becoming a lycanthrope section of this book is not legal for Pathfinder Society play unless noted on a future Chronicle sheet.

Equipment: all equipment on page 30 are legal; Magic Items: all magic items on pages 30-31 are legal; Mystery: the lunar mystery is legal for play.

From that alone, it looks like the additional class features under some skinwalker types are not legal for play, even for a skinwalker character. So things like the Wereboar-kin rage powers and Werecrocodile-kin hexes are illegal, even for characters of those heritages.

My question is, am I reading that correctly? And if so, is that the intention? People locally have assumed they were legal if you were that type of skinwalker, but I was not as positive and wanted a consensus here.
