If it's the first armor/weapon you craft, you'll have to start with Tier 1.
Use the selectors to choose what type of item you want to craft. It's important to know that the choice you make cannot be modified later.
Once you have decided which object you want to create, check that you have the necessary materials to start the Creation process.
It is not essential to have all the necessary materials to complete the next steps, Styling and Assembly, although you will need them to finish crafting your weapon or armor.
Use the "Start Creation" button to get the craftsman to start working.
The duration of this step will be: 4h for Tier 1, 8h for Tier 2 and 12h for Tier 3.
