witchcraft runes is a mod that aims to bring the old magic runes functionality from The Runic Dust mod, to the current version of Minecraft. In fact it is a new codification of the mod, since its author left the project abandoned.
For those who haven’t heard of it, it’s a mod that allows us to use “Arcane Dust” (similar in appearance to Redstone) to create runes on any solid surface in the world. These runes will impart effects and abilities to characters within range of the rune.
