SENSE MUTATION

You can sense if another creature possesses some form of subtle mutation.

Benefit: If you spend a full-round action observing a creature within 30 feet of you, you can determine whether or not it is a mutant. Make a Perception check opposed by the target’s Disguise check. (If the target is not the same species as you, it gets a +5 bonus on its check.) If you win the opposed check, you know whether or not the creature has any mutations, but not the number or types of mutations. If you beat the target’s Disguise check by 5 or more, you can correctly identify all the creature’s cosmetic mutations and deformities (but not its beneficial mutations). If you beat the check by 10 or more, you correctly identify all the creature’s mutations, including physical and psychic mutations.

Special: If you fail the opposed check by 5 or more, you cannot attempt another check against the same creature for 24 hours.
