This one page document makes it easier for the GM to use fear checks. While the CRB (page 243-244) presents suggestions for spending symbols, it is badly organized. Now this document gives you a nicely and properly formatted table with the author's personal suggestions on symbol usage, as well as basics tips for when making fear checks as well as using the Fear motivation when making these checks.
While it was made as a small supplement to Something Strange setting, there is nothing setting exclusive inside this document and it should be considered as a generic supplement.
For anyone running an adventure in which you expect to roll fear checks, it's a cheap and useful document to have.
