Blueprints | Enemies Dying Light Guide
Last update: 11 May 2016
Blueprints are in my opinion most important branch of crafting in Dying Light, because they are used to create new items. You can mostly find them in the game world (they are usually well hidden, sometimes in locked containers), but they can also be found by merchants and you are awarded with them for completing some missions. You should definitely unlock the Survival Starter Kit ability that can be found in Survivor tree, thanks to which you will get a free set of basic blueprints.
Thanks to blueprints you can most of all create new weapons with unusual properties (like the ability to set enemy on fire or electroshock them). You can find blueprints for creating throwing items (like stars) and one-time use items as well. As for the last ones, you should be especially interested with health kits and lockpicks, which should be created whenever you have the opportunity. It is good to have reserve of those items all the time.
Sadly, the game won't allow you to create new items with no limits, since you must always have the materials shown after selecting a specific blueprint. Try to regularly gather all items that can be used in crafting, especially since they don't take slots in inventory. If you plan to create an unique weapon from a blueprint, you must have one specimen of standard version of that weapon as well.
Important - Crafting materials can be purchased from merchants, but it is unadvised to buy them until you become quite rich. You should simply remember to thoroughly (with the use of survivor sense) explore all locations visited.
