I'm running a great spider and see strike fear but I can't find the rules for fear in the game. Anyone have a page number?

Hi, Sinister.

Fear Tests are one of the typical tests described in the Resolving Tests section of the Loremaster's Book, p. 29.

They test Valour (where Corruption Tests correspondingly test Wisdom), linked to Heart if Hope is to be invoked.
If failed, they are daunted to a degree preventing the fearful character from invoking Hope for any other Attribute bonus, for as long as they're exposed to the source of the fear. They don't have to flee it, but that might be a sensible course of action.

Cheers,
--Os.

Osric has answered your question. Figured I would post the following reference just in case "How do you break out of Fear?" is the next question you have. The last message in this topic, Zombie Apocalypse Tor - Part 3, the wrap-up should answer that question.
