Dresden Files - Can't go home again
A Game Session = Minor Milestone
Every 3 or so Game Sessions (i.e. “a story arc”) = Significant Milestone (which gives you a skill point)
When you get enough Skill Points to equal the next Refresh level, it automatically upgrades to a Major.
This way your character never falls behind in Skill Points compared with Refresh.
ExampleA character was created at 7/25 “Up To Your Waist” power level. The character goes through five story arcs and now has 5 Significant Milestones. This means they have 30 Skill Points. 30 Skill Points is the “Chest Deep” power level, which is 8/30. Poof. The most recent Significant that the character received (i.e. the 5th one) automatically upgrades itself to a Major Milestone and the character gains a Refresh.
