In order to be able to learn how to make them, I know you need five fragments of power. What I am unclear on is, do you have to learn a feat in order to make the tablet? I looked up the Wiki and it is not clear at all. I guess I understand it wrong but it seems to say that you just handcraft them. If there is a feat before you can do that, where is it? There is no tablet of power in my handcraft menu.
Ah jeez, the Wiki does indeed say you need a feat that you learn in the archives, so I apologize for this.
