It doesn't help that even legendary daedric artifacts will be obsolete in a few levels unless you get them extremely late in the game ( level +25 IIRC ).
This is a minor quibble, but I hate having to correct it constantly -
Daedric artifacts are not affected by level scaling. You are locked off from Daedric quests until you are a high enough level, so those rewards are static. You need to be Level 20 before you can do Boethiah's quest and receive Goldbrand, so Goldbrand will
always have 25 base damage and have a 22 pt. Fire Damage enchantment. Other quest rewards are level-scaled because the player can pick them up at any time, and this is where you get all of the items whose stats/enchantments are based on ranges of Levels 1-4, 5-9 etc. until topping out at 25+ such as
the Escutcheon of Chorrol, Chillrend and so on.
