Cairn Items & Crafting Recipes: The Stove, the Scraps and the Compost
Cairn has no workbench and no crafting tree. There is nothing to unlock and no station tier to grind toward. Instead the game splits making things into three small loops you already walk past: cook at the camp stove in every bivouac, have Climbot rebuild pitons from scrap, and compost trash into chalk. This page is also the site's item index: everything Aava can carry, eat, craft or lose, grouped below, with the detailed numbers kept on the dedicated gear and resource pages. All mechanics are verified against the release version (January 29, 2026, PC and PS5); where the game keeps values hidden, we describe outcomes instead of inventing numbers.

Cairn Items: Index by Category
Four categories cover every item the game lets you hold. Nothing here is a crafting exclusive: the only items you can make are food, drinks, pitons and chalk. The rest of the list is found by exploring Mount Kami. Use this table to locate an item, then follow the link for carry limits, sources and the exact rules.
Eat raw to survive; cook at the camp stove to restore more per slot and add timed buffs. Medicine heals and is best spent after a fall, not before a crux.
Every crafted item in Cairn comes out of one of these loops. None of them require anything you will not have by the end of the training gym. The limit is ingredients and attention rather than unlocks.
Loop
Where
Input
Output
Notes
Cooking
Camp stove, inside any bivouac
Foraged plants, loot, water
Meals and drinks: better restoration plus timed buffs
Also reheats existing food to top up your temperature meter
Piton crafting
Climbot, at any bivouac
2 sets of piton scraps
1 functional piton
Scraps drop from failed placements and loot containers
Chalk production
Climbot, at any bivouac
Trash (wrappers, broken items, waste)
Chalk for the next 12 handholds per application
Compost everything you do not carry; chalk is meant to be spent
The whole crafting system fits in one tent: the stove converts ingredients into food and buffs, Climbot converts scraps and trash into pitons and chalk, and the backpack carries the results up.
How Cooking Works
Select the camp stove and the cooking interface lets you combine consumables into better ones. Drinks form the backbone: a liquid base plus ingredients produces teas, infusions and juices that restore thirst alongside energy, health or timed buffs. Food works the same way: raw plants keep you alive, but combined meals restore more per slot and often carry a modifier such as sweet, herbal or intense, depending on what went in.
Two habits separate fed climbers from starving ones. First, reheat: the stove can warm up existing meals and drinks to top up your temperature meter, which makes any cooked item double as a heat source before cold sections. Second, sequence: several recipes grant buffs that run on timers, so the efficient order at every bivouac is sleep first, then cook and eat. The timers then spend themselves on the wall instead of in the tent.
Buff
What It Does
Best Spent On
Burst
Move and climb faster
Long traverses and easy ground where speed saves meters
Focus
Supports precise, sustained climbing
Technical sections with small or awkward holds
Grip
Stronger grip on holds
Cruxes and small-hold walls; pair with chalk
Grit
Toughens you against strain
Sections where bad holds or stumbles are likely
Warmth
Raises body temperature
Cold snaps, night climbing, exposed upper-mountain pushes
Buff timers only pay off if the wall in front of you is the right shape for them, so pairing a recipe with a route choice beats cooking generically. Grip and focus earn their slot on technical ground; burst pays on approaches and long traverses; warmth is for cold snaps and night pushes.
Ingredients: Where They Come From
Cooking is only as good as your foraging. Mount Kami restocks you constantly if you pay attention on the approach as well as on the wall.
Grow all over the mountain; free calories and drink ingredients
Loot containers
Packaged food, drinks, medical supplies, climbing tape, piton scraps
First aid kits, vending machines, bear-proof boxes and cooling pots sit at fixed spots worth revisiting
Water sources
Streams, ponds, and rock cracks that fill bottles directly
Refill bottles at bivouacs without leaving the tent
Abandoned camps
Mixed supplies: food, gear, sometimes recipes
Scavenge climbing gear or cooking ingredients; both feed the ascent differently
Trash
Compost material for chalk
Processed food creates wrappers and waste. Turn them into grip
The Climbot Economy: Scraps and Trash Are Currency
The two Climbot loops reward a specific mindset: nothing broken is worthless. Piton scraps from failed placements are half a piton each, and two sets rebuild one you can place again. Wrappers, broken gear and food waste become chalk, and chalk covers your next twelve handholds with extra grip. Both outputs are things you should be spending liberally, which means both inputs are worth bending your route to collect.
Grab scraps immediately
Failed placements and loot leave scrap behind. Collect it before you leave the ledge; two sets are a free piton at the next bivouac. Piton placement and recovery decides how much scrap you see.
Compost before you climb
Eat packaged food early, compost the waste, and start every push with a full chalk bag. Chalk hoarded is grip wasted. Chalk lowers the stamina cost of every move, which is why it earns its slot.
Backpack space rather than weight is the real constraint: the bag is limited by physical room, so finished food and drinks outperform a pantry of raw bulk. See the gear guide for carry limits and the quick-slot layout, and the resources guide for how much of each supply a day actually burns.
FAQ
Is there a crafting table in Cairn?
No. Cairn has no workbench, forge or recipe-tree UI. Crafting happens in three places: the camp stove inside your bivouac turns ingredients into meals and drinks, Climbot combines two sets of piton scraps into one functional piton, and composting trash with Climbot produces chalk. Everything else you use (tape, medicine, gear upgrades) is found by exploring; nothing is manufactured.
How do I craft more pitons?
Collect piton scraps: they drop from failed placements and are found in loot around campsites and bivouacs. At any bivouac, select Climbot and it will combine two sets of scraps into one fully functional piton. Because failed placements still drop scrap, a botched placement is a partial refund rather than a total loss. Grab scraps before you move on; they do not follow you up the wall.
What should I cook first?
Start simple: water plus a sweet ingredient makes a drink that restores hydration and energy at the same time, and fruit cooked into juice does similar work for hunger and thirst together. Herbal infusions restore thirst while adding health or timed buffs. Once you have a rotation of two or three drinks that cover thirst, energy and warmth, refine toward recipes whose buffs match the next section: grip for cruxes, burst for long traverses, warmth for cold pushes.
Do food buffs stack?
Buffs are timed effects, and each buffed item runs its own timer after you eat it. The practical consequence is sequencing: sleep first, then cook and eat, so the timers tick away while you climb instead of while you rest. Reheating food and drinks at the stove tops up your temperature meter without consuming the meal, so a cold morning is solved by the stove rather than by cooking something new.
Where do new recipes come from?
Recipes are discovered by exploring (notes and examples are found in troglodyte structures and abandoned camps) and by experimenting at the stove: most ingredients can be combined, and modifiers like sweet, herbal or intense come from what you add. Players have catalogued well over a hundred combinations, but you only need a handful of reliable meals to keep Aava fed, hydrated and buffed for the whole ascent.
