I'm currently trying to design a method of organizing the monsters from all the sets, and was planning on grouping them by their RtL categories (humanoid, beast, eldritch) and realized that I had left all the other game components (i.e. the rules and cards) at a friend's place. While I can get most of the monsters' classes from the RtL pdf, the ToI pdf doesn't list the categories to which the new monsters belong.

So on to my question: To which category do the following monsters belong (in brackets are my vague rememberences; please correct me if I'm wrong)

Lava Beetle
Shade
Medusa (Humanoid?)
Wendigo (Beast?)
Ice Wyrm (Eldritch?)

On a side note, does anyone know why the ToI pdf is about ten times the file size of any of the other rulebooks?

Medusae are the only Humanoids. Wendigos and Lava Beetles are Beasts and Ice Wyrms and Shades are Eldritch.

As for the pdf, I suspect they didn't reduce the graphics from the print-quality version.
