En varelse som har tillgång till flera olika favoriserade klassbonusar för samma klass kan välja en annan favoriserad klassbonus varje gång varelsen får en nivå i sin favoriserade klass. Favorited Class , delvis, säger

The choice of favored class cannot be changed once the character is created, and the choice of gaining a hit point or a skill rank each time a character gains a level (including his first level) cannot be changed once made for a particular level.

Den avancerade spelarhandboken på Racial Favored Classes -tankfullt - gör det här lite tydligare, delvis sagt:

The normal benefit of having a favored class is simple and effective: your character gains one extra hit point or one extra skill rank each time she gains a level in that class (or in either of two classes, if she is a half-elf).… In most cases, these benefits are gained on a level-by-level basis—your character gains the specified incremental benefit each time she gains a level. Unless otherwise noted, these benefits always stack with themselves.… In some cases this benefit may eventually hit a fixed numerical limit, after which selecting that favored class benefit has no effect. Of course, you can still select the bonus hit point or skill rank as your favored class benefit, so there is always a reward for sticking with a favored class.
