Into the Breeding Pits Questions

[Karasu]

Does the Bottle of Time count as a potion?
If so, is it Greater or Lesser, per Dark Alchemy rules?
If Greater, any idea how much the ingredients cost?

Would it be worthwhile doing an updated treasure table including items from all the books?
Some of the items that are only found in specific tables seem like they could be appropriate anywhere.

I'm interested why some things are Animals and other ones aren't.  Giant Wyrms and Hydras are, but Basilisks and Devourers aren't.  I can't see the difference, am I missing something?
