In Dragon Project, you create your own weapons and armor in the Armory using the materials dropped by slain monsters.
To forge weapons and armor, simply follow these instructions:
  1. Tap the circle icon located at the bottom right of your screen.
  2. Tap "Armory".
  3. Tap "Forge" to talk to Boldon the Blacksmith.
  4. Tap "Weapon" to create a new weapon or tap "Armor" to make a new armor.
Note that you'll also need to spend some gold coins when making a new weapon or armor.
