Even though I own Root and Bluebeard's Bride that is still $270 of product I don't own (and even at 50% off paying $41 is still a good bargain).

Although I'm probably only interested in Avatar Legends ($114 retail) which is not quite the whole line just the major books. Masks is also a line with more supplements than in this bundle.

Probably buy but might change my mind.
