Assassin's Creed Valhalla · Gear progression
Gear Quality Enhancement
Enhancing gear changes its quality, adding upgrade and rune slots; the guide says the enhancement itself does not increase gear stats.
How it works
The guide lists four quality levels: Fine, Superior, Flawless, and Mythical. Fine has 2 upgrade slots and no rune slots; Superior has 4 and 1; Flawless has 7 and 2; Mythical has 10 and 3. It says enhancement does not increase stats, requires a blacksmith, and uses carbon, nickel, or tungsten ingots depending on level. It reports enhancements may also change appearance.
