Item description:

save has a armour set in inventory to be invincible on all difficulties including legendary, i have tested this myself with a giant.

there is a gold bracelet in your inventory that is enchanted with fortify alchemy which you can use to make fortify enchant potions with and make even more enchanted gear as you wish as you progress in the game.

to max out your level and get as many skill points as you want create a ring with the fortify enchanted potion in your inventory and enchant the ring with low alteration cost, equip the ring and then use telekinesis and fast travel to a far location to level up alteration, reset skill and repeat over and over.

there is a area right outside windhelm near the main gates with lots of items, take whatever you wish from there or drop more items to duplicate whatever you want, there is also a location at Helgen with over 100 ebony arrows plus more room to duplicate whatever you want from there, just go in the castle in that area to access it.

talk to your companion to access all of his items in his inventory.
