[@TheUnknowable] I literally mean rocks I have picked off the ground to carve runes into. The way I imagined them is having them glow like a candle flame once the enchantment was completed. Maybe tied to a keyword for activation. I figured enchantment was pretty powerful that's why I only gave him one weak spell he could do it with at start. Elemental stones Zane understands but cannot use.

I don't see any reason you couldn't have that ability!
