I just got my Smithing level to 100 and have made all of the Daedric armor and weapons that I want. I'm working on Enchanting and Alchemy, so that I can enchant Alchemy armor to the max % boost and create the best enchanted Smithing % boost to sharpen and strengthen my armor and weapons. Is this the best way to get the best armor and weapon ratings?

Using alchemy and enchantments are definately the best way to upgrade weapons and armour past legendary.

I wouldn't do it though. Why? Because it's pointless and boring.

You just end up with OP weapons that kill the challenge.

Me? I stick to a skyforge steel sword - it looks the part and does satisfactory damage. Deadric equipment looks silly on anything but Deadra IMHO.

See this thread for all the info you want:

It's locked now (post limit), but we'll get the ninth one up soon, I'm sure.
