The Weapon Recipes NPC has a list of all of the materials you need for each weapon. Displayed in a neat list with all the additional information such as the Damage, Range, Knockback, Ammo, Rarity and more.
You can click on any of the chests to open the crafting recipe for that weapon.
You can navigate through the recipes by click on the left glass panes to go to the previous recipe or right to go to the next recipe. You can craft in any workbench around the spawn area.
We're soon adding an option to quick craft the weapon.
