Your anatomy allows you to benefit from additional magic rings.
Prerequisite(s): Three or more hands.
Benefit(s): The number of magic rings that you can effectively wear at one time is limited by the number of hands you possess. This does not apply to temporary forms (such as when under the effects of alter self or polymorph), but the permanent possession of three or more limbs ending in hands.
Normal: A character can only effectively wear two magic rings. A third magic ring doesn’t work if the wearer is already wearing two magic rings.
