The scaling is a bit ridiculous late-game.
Take level 17 to level 19 for example; Armor values go from roughly 300 armor total on a chest piece to 800+ at level 19. 2H weapon damage goes from ~120 to close to 200. Daggers go from ~60 damage to ~95 damage. It took 17 levels to get daggers to ~60 damage, but only 2 levels thereafter to increase a dagger's base damage by more than 50% from level 17? Something weird. Which is why I don't craft unique items until late game, because they're worthless by then if you craft as soon as available (Level 15 Eternal Armor compared to level 20 - Good thing you can find enough materials to craft this armor 3 or 4 times throughout late-game though).
