About Refined Heart

Refinement Material

Specialized refinement material for "Rainbow Serpent's Rain Bow." A brightly colored, exquisitely crafted finger guard long worn by archers. The accuracy of an arrow hinges on the archer's experience: The more one draws the bowstring with focused breath, the more seamlessly bow and arrow move in unison. To nock and draw is to temper the spirit. The wear on the guard reflects the sharpness of the archer's resolve.

Used by the supported upgrade goals listed below. Requirements depend on the selected current and target levels.
