Nu har jag bara någon framgooglad webbsideversion att kika på, men enligt den verkar kapitlet om nycklar och erfarenhet börja på sidan 50.
Ett litet urklipp:
"Gaming And Using Advances
The primary means of gaining experience points during play is for characters to do things or have things done to them — events of play, in other words. Whenever such events happen to trigger a Key possessed by a character, the player should make mention of this to the other players and jot down the number of experience points gained. (Shouting “Bingo!” would be cheeky, but not entirely inappropriate.)
What this means in practice is that players will constantly maneuver their characters into situations that are pertinent to their Keys: this will allow the player to develop the character and the character to gain strength for important conflicts ahead in his story. Such strength may then be brought to bear when it really matters."
