Changes

To start with, p. 119 of the Corebook has a table with some standard Difficulties, pp. 407 - 414 has typical dice pools you might want to know, p. 409 has Difficulties for Feats of Strength and pp. 411 - 412 has more detailed Difficulties for social situations and circumstantial modifiers (e.g. if you're asking someone who dislikes you to do something risky). I recommend checking these sections before continuing, as these are the basics.

* Cons: Need to improvise quickly if a half-stated statted SPC is suddenly challenged
