Heyas, I'm slightly confused about the wording of this.
Unique + Runestone ======> Set Item (if Applicable)
So earlier in this thread I read that this only applies to Sacred Uniques. But as for the Runestone, does it mean the blank Runestone found in Toraja that's used with the elemental essences? That's the only item that seems to be referred to as a "Runestone". Every other rune is called a "rune" according to the docs. Or does any rune work?
