=== Resplendent Destiny ===

For a Resplendent Destiny, you'll have to start by spending two Effect Points (technically to cover Scope, but just think of it as a tax) then divide the rest into two pools.  Given that the five dice used as an example above will tend to yield two Successes, you can see why all the extra bits used to increase the number of Effect Points are so necessary.  
* Duration - Effect Points spent on duration will determine how long the Resplendent Destiny is available, use the table on page 219.  These points are spent and unavailable for Powers.
* Powers - You use these to buy the powers listed for each constellation as if the Effect Points were Essence (they're not, I'm using an analogy here) and the Powers were charms that are made available by having a Resplendent Destiny (more analogy).
The Resplendent Destiny will last for as long as the duration that you bought or until you're out of Effect Points, whichever comes first.

It's easy to see how to use the powers, they're in the same general catagory as Charms and Spells, but one of the main uses of a Resplendent Destiny is as a temporary identiy that you can turn on and off at will.  The mechanics for it are on page 216, but the gist of it is that you can turn your Resplendent Destiny On (One temporary Willpower and a simple action) and people will remember you as the type of person that is stereotypical of the Constellation that you took the Respelendent Destiny from.  Your (probably assumed) name will be remembered as well as your actions, Arcane Fate is put aside for as long as the Resplendent Destiny lasts (regardless of whether you're "wearing" it or not).  The downside is that you have to choose an identity and stick with it, always acting in character while you have it On.
