Items

Villedor hands out very little for free. Aiden's health and stamina only grow when you inject Inhibitors, a blueprint only improves when you feed it Infected Trophies, and the Nightrunner tools that open up the Central Loop stay at their base level until you pull Military Tech out of a rooftop airdrop. This guide gathers everything our Dying Light 2 item pages cover: what each resource does, where it actually comes from, and which ones deserve your time first. For the systems that spend these resources, such as weapon repair and lockpicking, see the mechanics guide.

Every resource at a glance

Inhibitors

A single Inhibitor does nothing. Bank three and you can inject them for one upgrade to health, stamina or immunity, and that is the only way those bars grow in Dying Light 2. Our tips page makes the case for stamina first, because climbing and ledge grabs drain it long before health becomes the problem, and our health and stamina page points out that the early game hands you six without much effort: two upgrades before you have really started exploring.

How the game points you at them

Aiden's GRE Access Key speaks up whenever an Inhibitor sits within 50 meters, and a distance readout appears in the lower-left corner of the screen. Close to within 10 meters, switch on Survival Sense and the container lights up. That is enough for the early districts. Once the main quest "Broadcast" is done, go back to the VNC Tower and speak to Lieutenant Row for the GRE Detector Tool, which plots every Inhibitor inside the coverage of any Radio Tower you have activated. Light up all six towers and the whole map is annotated for you.

Where they cluster

Our Inhibitor locations guide walks 38 spots that hold 63 Inhibitors between them, and most spots hold two or three. Grouped by district, the pattern is clear: Horseshoe and Trinity are the richest early hunting grounds, Downtown and Garrison carry the Central Loop's share, and a handful sit in water or on quest paths you will cross anyway.

Two of the safes in that list have their combinations on our safe codes page: the Downtown safe near the bandit camp opens with 3 1 3, and the Garrison Electrical Station safe in Room C opens with 3 1 4. The Anomaly Inhibitors only appear at night, after you have beaten the boss infected guarding each site, so plan those visits around the clock.

Blueprints

Stay Human changed how blueprints reach you. You no longer stumble on random recipes in the world; each one is unlocked by a quest or bought from a specific vendor, and it then lives in your inventory for good. Upgrading a recipe costs Infected Trophies at the Craftmaster's Upgrade tab, with uncommon trophies covering the first tiers and rare ones needed higher up. Our blueprints page lists 33 item recipes and 29 weapon-mod recipes with their sources, which break down like this.

If you only upgrade three recipes, our writers pick the Lockpick, because picks are almost never found and every locked car and chest wants one; the Molotov, whose fire burns longer than the other fire options and holds a wave of infected in place; and the Remote C4, the best explosive in the game, although its blueprint only reaches you in the second half of the story. The Reinforcement grip is worth a mention too, since it slows durability loss on whatever weapon carries it, as covered in our weapon repair guide.

Infected Trophies

Trophies are tokens that appear in your inventory when you loot a dead infected, and they are the currency for every blueprint, lockpick and mod upgrade. They come in three rarities, each tied to a class of enemy.

Infected marked with a blue Encounter icon on the map always drop a trophy, and any other infected has a chance to, so search every body. Two settings tilt the odds further: the drop rate rises on lower difficulty, and resting at any safe spot to push the clock to night fills the streets with spawns. Full farming notes are on our Infected Trophies page.

Military Tech

This is the scarcest material in the game and the only one that upgrades Nightrunner tools. Unexplored airdrops show as question marks on the map; look at one through the binoculars and it turns into a parachute icon, red if Aiden cannot reach it yet because he lacks the stamina or the Paraglider. A parachute draped over a rooftop is the same tell. Inside the crate the tech is easy to walk past: check the right-hand side of the open chest and interact with the GRE key. Spend it at a Craftmaster's Upgrade tab, where the Paraglider, Grappling Hook and other tool upgrades cost roughly one to three pieces each. Our Military Tech page has the full walkthrough, and the airdrops themselves are also one of the better XP sources in our leveling guide.

Feathers

Ranger-style play runs on feathers, which go into arrows, crossbow bolts and weapon upgrades. They come from Birdhouses on rooftops, usually one or two per box, and the boxes sit among rooftop gardens of Chamomile, Cordyceps, UV Shrooms, Honey and Lavender. When you notice a trail of pickable plants, you are close to one. Feathers sell to merchants for a little Old World Money, but they are scarce enough that our feathers page advises keeping them for crafting.

Trinity Graffiti

Murals are painted across every district, but seeing one is not enough: the collectible only registers when you pick up the spray cans lying nearby and tag the wall. Our Trinity graffiti page maps the nine in Trinity, and the cans follow a pattern of being within a few steps of each piece.

Frequently asked questions

Do I need the GRE Detector to find Inhibitors?

No. The GRE Access Key's voice line and distance readout work from the start, and Survival Sense pinpoints a container once you are within 10 meters. The detector, unlocked after Broadcast, simply marks every Inhibitor within active Radio Tower range on your map.

Which vendor stocks the most blueprints?

The Peacekeepers Floating Fortress vendor, with nine item recipes and seven weapon mods on our page's list. The Fish Eye and Bazaar vendors carry eleven recipes each.

Can Military Tech be used on weapons?

No. It only pays for Nightrunner tool upgrades. Weapon mods are crafted from scrap, rags and other junk, and their recipes are upgraded with Infected Trophies.

Are any of these collectibles tied to story choices?

Only indirectly. The Regeneration Booster blueprint depends on helping Jack and Joe at their camp, and the six bolt recipes arrive at city alignment level 4 with the Peacekeepers, which depends on the facilities you assign them in our faction assignment guide.
