From Nightingale Wiki

Nightingale features a robust crafting system that allows players to create items and customize or decorate them in their own way.[1]

The crafting system allows players to create tools, weapons, and gear, but also to customize their outfits.

"We want our players to be the Realmwalker that they want to be in this world. That means there are character choices and customization. You want a different color coat? Then go craft a different color coat or get your friend to craft it for you, whatever works." – Aaryn Flynn[2]
