You skin, hair, and other natural coverings alter their lucidness, appearance, and color - in effect, allowing you to subtly change colors. This allows you to hide, if stationary, almost as if invisible.
Benefit
You gain a +4 mutation bonus to Stealth checks.
In addition, as a full-round action, you can become nearly invisible. You gain a 25% miss chance and can hide in plain sight. This benefit remains until you take an action that includes physical movement, such as attacking with a weapon, casting a spell with a somatic component, physically interacting with a creature or object, or moving from your current location.
Special
This bonus is reduced to +2 if you wear clothing or armor. Wearing heavy armor or clothing that fully covers your body negates this bonus entirely.
