Akradon: I don't think there is a fotify enchanting enchantment, at least I've never seen one in my 3 plathroughs. The best I could suggest is to get your alchemy level up and create a potion with two of the following ingredients:
- Blue Butterfly Wing
- Hagraven Claw
- Spriggan Sap
Drink one just before you enchant things :)
Pretty much this. The "loop" goes like this;
- Use a Potion for Fortify Enchanting
- Drink Potion while Enchanting a new Fortify Potion Armor (Grieves, Necklace, Ring and Circlet)
- Create a new Potion for Fortifying Enchantments while wearing the new Fortify Potion Armor
- Drink the new Potion (with higher Percentage for Fortify Enchantments) and create new Set of Armor (again) for Fortify Potions
- Rinse and repeat
It should obtain a Theoretical Maximum of 32% better Armor for creating Potions. After this, you're almost finished. Now you should be able to make a Fortify Smith Potion for around 110+/ 150+ Fortify Smith (depends on how high of a Percentage from your Enchanted Armor). Make one last set of Enchanted Fortify Smith Armor while drinking a Potion for Fortify Enchantment and make a Set of Fortify Smith Armor. You apply this to the Ring, Grieves, Necklace and Body.
You should now have a Fortified Smith (Enchanted) Armor (any clothes will do fine for the Body, I used a Chef Outfit and called it "Tunic of the Smith", "Ring of the Smith" etc) and a Potion for Fortify Smith (110+/ 150+). Wear/ drink your "Smith" and make your truly Legendary Armor/ Weapons.
