Can anyone explain to me what the hell you do with blank spell books? I have one for witchcraft but I don't know how to make it an actual spell...I assume some sort of crafting needs to happen but I'm at a loss. I tried looking it up and didn't find anything useful
I actually just found a book that indicates you have to enchant a quill & ink in order to inscribe your own skillbooks. I haven't gone any further with it.
Fairy dust is the key (Magic dust? I forget what it's called)
