As per smithing enchants and so on i STRONGLY advise you to max your smithing and get the pieces you need and upgrade them to the wanted level of upgrading THEN put them legendary and use those perk points to. The perks are minimal tho 100 is the aim so you get extra perk that you can spen somewhere else. This woudl be a pretty broad aspect of a godo assin build WITH maximum dmg output.Skyrim Best Mage Build For Legendary Difficulty Once created equip the set and then make some fortify enchanting potions.Drink the potions while you create a second more powerful set of fortify alchemy gear. For this part anything will do, I use leather and silver jewellery, but make sure you always use grand souls for the enchanting. Except maybe not smithing for a pure mage if have no intention of using a physical weapon or armour.Perks needed:Alchemist 5/5BenefactorEnchanter 5/5Insightful EnchanterCorpus EnchanterExtra Effect (Optional but recommended)If taking smithing just get the required perks for what type of weapons/armour you intend to use.This combination will allow you to make heavily enchanted gloves, helmet, ring and amulet that fortifies your alchemy skill. My advice would be whichever class you're playing on legendary make sure you get alchemy, enchanting and smithing up to 100 as soon as possible.
