By the looks of the FAQ on the updated (and very pretty) Issaries
site, it looks like you have to Incorporate 3 relevant spirits, and
get them all to an appropriate level (5W2 wasn't it?) before you can
get the Secret of shapeshifting. Correct? Looks like the basic rules
carry the basic info on Hsunchen anyway...
