Mother f*cking iron ingots and leather strips
How to get these?
Mine iron and get leather from animals (if you have time)
Or be a lazy f*ck and spawn it in from the console (~ or ` to open console). Don't know the command or the item id? Look it up f*cknut

Get your mother f*cking ass to any blacksmith (Like whiterun cuz that sh*t in the centre of the map) and use that forge to craft yo sh*t

Craft a f*cking ♥♥♥♥ ton of iron helmets, honestly your inventory will have like 1000 before your smithing skill is level 100.

You can f*cknut, just legendary that sh*t and keep going

You have a mother f*cking ton of perk points and stats, do whatever you do in skyrim, like murder everyone, r*pe children, whatever your personal preference is :)
