Through your understanding of the flow of energy in the hands, you can initiate the power of more than one ring in the same hand.
Benefit(s): You may have two magic rings active simultaneously on the same hand. The second ring must be worn on the thumb in order to remain in effect. When this feat is taken you must select which hand it applies to.
This feat can be taken multiple times, each time applying to a different hand.
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.
