Shifting (Su): A shifter can tap into her lycanthropic heritage to gain short bursts of physical powers. Once per day, a shifter can enter a state that is superficially similar to a barbarian's rage. Each shifter has one of six shifter traits-characteristics that manifest themselves when a character is shifting. Each shifter trait provides a +2 bonus to one of the character's physical ability scores (Strength, Dexterity, Constitution) and grants some other advantage as well.
Shifting is a free action and lasts for a number of rounds equal to 3+Con modifier. (If a shifter trait or other effect increases the character's Con modifier, use the newly improved modifier.) A shifter can take feats to improved this ability. These shifter feats are described in the book.
Every shifter feat a character takes increases the duration of shifting by 1 round. For every two shifter feats a character takes, the number of times per day she can tap into the ability increases by one.
Shifting, though related to and developed from lycanthropy, is neither an affliction nor a curse. It is not passed on by bite or claw attacks, and a shifter can't be cured-shifting is a natural ability for the race.

Shifters are basically descended from lycanthropes in general, not any one specific lycanthrope. Basically it is the intermingling of the species over time and you can't really state my grandfather was a weretiger and mommy was a wererat. Your talking generations and generations of mixing. Hope this helps. There are several different shifter traits the shifter can take, each provides a differing bonus or ability and relates to specific ability scores. You can only choose one trait, but later on it is possible to take more traits.
