-does creture analysis work on undead or spirits?

-what counts as a creature? (for Knowledge: Creature Lore)

Creature Analysis/Lore generally works on anything in the Creatures section of the books. For other sections Dragons, Horrors, and Spirits, the talent and skill will not work. Generally you'd need Dragon Lore, Horror Lore, Spirit Lore, or Undead Lore (more specialized version of Horror Lore that covers just the undead types and also Nethermancer spells that create undead) for that. There is a talent knack called Horror Analysis that allows you to use Creature Analysis against Horrors and Horror constructs, and you can use this to expand to create other talent knacks as well such as Dragon Analysis or Spirit Analysis or even Undead Analysis if you would like.

So for summary:
Creature Lore/Creature Analysis: Creatures Section.
Beastmasters, Beastlords, and Woodsman have Half-magic Creature Lore
Cavalrymen and War Riders have Half-magic Creature Lore for mounts
Dragon Lore: Dragons Section.
Spirit Lore: Spirits Section.
Elementalists have Half-magic Spirit Lore for Elemental Spirits.
Nethermancers have Half-magic Spirit Lore for Ally Spirits.
Shamans have Half-magic Spirit Lore for Nature Spirits.
Horror Lore/Horror Analysis talent knack: Horror Section.
Horror Stalkers have Half-magic Horror Lore
Undead Lore: Horror constructs and Nethermancer spells covering the undead.
Nethermancers have this as Half-magic Undead Lore.
