|Heroic Action Role-Play|
You are an incarnation of some archetype; generally a common type of monster, but other themes are certainly possible. This can also apply to more narrow magical traditions. All your Powers must relate to this theme, and the theme must be fairly specific.
Incarnate is a build limitation; it does not affect how you in play. Typically an incarnate has access to either a number of Forms equal to their Maximum Value -10. Some characters are limited by technique instead and can use a number of skills equal to half this.
Some incarnates have both forms and skills limited, or even fewer forms or skills available (half of the above, with a minimum of one) - in both cases this is a two-point limitation.
