i just created a full set of dragonplate armor + shield and i want to upgrade it. i heard the armor rating is capped at 567? (someone confirm)
i do not know how to get the rating that high up, what perks will i need and etc?

explain this to me like you would explain it to a baby

the cap is indeed 567. To meet the cap, you need to increase your smithing skill and then upgrade the armour at a blacksmith. you may need enchanted gear to raise your smithing high enough, and/or you could get some potions that will give you a boost as well. If you created the armour yourself you must already have the dragon armour perk, so thats not an issue.

thanks, do you know the name of the potion and what i need to make one?
