Crafting uses recipes to combine two or more items to create a new, unique item. There are currently two types of recipes: Common Recipes and Secret Recipes. The crafting menu can be found as a tab in your inventory.
Common recipes can be crafted by anyone at anytime.
Secret recipes come from Recipe Bottles that are hidden throughout the site. Simply having the recipe in your inventory allows you to use it on the crafting menu. Crafting from a recipe does not destroy the recipe. They can be traded and sold, but will not appear under the "all items" option.
