So I was reading how I could make Daedric items, including a Daedric Sword, which is what I want.
I already made one at the smithy but this one website said I needed a Dremer Dynamo core too.
I didn't need one to make a Daedric sword.
Am I missing something? Is there a more powerful version that incorporates a Dynamo core?

Thanks, all!

you were looking at the atronach forge. Wrong forge.

Yeah, the atronach forge lets you make Daedric items before you unlock the perk to do it at a blacksmith's. There are also recipes for making other items that are not forge-able by any other means.

THAT makes sense. BEFORE perks. Ah.

Yep, Atronarch Forge. I found that out when I went to the Atronarch forge later on after making Daedric weapons.
