Secrets of Xen'drik (Book Approval)

[Patlin]

I don't have this book, and the only one I recall is Echoing Spell. I'll vote YES to that feat, but as to the rest I don't have enough information to evaluate them.

I lack the book (I'm in the same boat as RA; little brother owns the books, except the ECS, so I only get to read when I'm in town).
