Band of Energetic Resonance

A strange purple-colored ruby adorns the silver details that loop into a mysterious ring.

When two successful attacks are made, the wearer regenerates a spell slot or resource point (Ki, Sorcery Point, etc.) or the use of a special skill or ability, with the exception of skills and abilities provided by other items or by extended effects of spells or magic.

This effect can only happen three times every long rest.
