A great addition to the Terrinoth series. Runebound shards are a key setting element in Terrinoth, so to have all these new options is awesome. Also great as generic magic items that allows both spell casters and non spell casters to use it different ways. I plan to use them in my Eberron conversion as a variant use of Kyber crystal etc.

One does not simply ever have enough treasure! Another hearty welcome to my game master's horde.

Keep up the good work!
