Overview
Grimnir is a dwarf artificer who works at the Kilnden Workshop, located west of Hernand. He is recognized as a brilliant engineer with considerable talent for his craft. Despite wearing a Visione on his head and possessing obvious skill as a craftsman, Grimnir's arrogant and self-centered nature frequently gets in the way. He acts dismissive when questioned and will not admit that he needs help, even when he clearly does. This difficult personality means that working with him requires patience, though his technical brilliance makes him one of the most valuable NPCs in the game.
Grimnir is the primary crafting NPC for Kuku Pot-related items. Players first encounter him during Chapter 4: The Price of Knowledge, and he remains relevant throughout the rest of the game as new crafting recipes unlock through faction progression.
Location
Grimnir can be found at the Kilnden Workshop, where he practices his trade. The workshop sits west of the Abyss Nexus in the Hernand region. Players can return to this location at any time after the initial Chapter 4 visit to access crafting services or pick up new recipes.
Chapter 4 Quest Involvement
Grimnir plays a central role in the Chapter 4: The Price of Knowledge story arc. When Kliff arrives at the Kilnden Workshop, Grimnir enlists the player's help to get things running again. Though he secretly wants assistance repairing the kilns, he will not admit it directly.
Kiln Repair at the Kilnden Workshop
The Kiln Repair at the Kilnden Workshop quest requires the player to fix three broken kilns for Grimnir. Each kiln presents a different puzzle:
Disconnected Kiln: Interact with the connecting pipe on the side to plug it in, then push the handle to activate it.
Dismantled Kiln: Requires assembling broken pieces using Axiom Force.
Third Kiln: The fuel orb is located in a small cave southeast of the kiln. Place it inside and push the yellow pole to activate.
Before the kilns can be repaired, the player must also solve a generator puzzle near Grimnir. An Ancient Generator has a wooden pole and a lever with three settings. Adjusting the lever causes different glowing runes to light up on the device.
The Mysterious Pot
After completing the kiln repairs, Grimnir agrees to craft the player a pot. The Kuku Iron Pot is produced during the quest called "The Mysterious Pot," which is the 49th main mission in the game. Grimnir restored an ancient Kuku Pot from nothing more than a memory fragment. This shows his extraordinary abilities as an artificer.
When the pot is ready, the player pushes a small crank along the edge of a stone circle, traveling clockwise until the ground opens and the pot shoots up. Togrum, another dwarf at the workshop, then teaches the player how to use it. The Kuku Iron Pot can store Abyss-type objects, machine parts, and contraptions across 230 storage slots. It can hold items of any size or weight, making it essential for puzzles that require moving heavy objects.
Crafting Services
Speaking to Grimnir at the Kilnden Workshop opens the crafting interface. His initial crafting options are limited, but new recipes unlock as the player progresses through the story and completes faction quests.
Unlocking New Recipes
Additional crafting options become available at specific story milestones:
Chapter 5 onward: Recipes tied to the Witch characters begin appearing.
Chapter 10 onward: Recipes connected to the Ironflame Orcs faction unlock.
Witch of Wisdom faction quests: Completing Sanctum challenges for Elowen yields crafting blueprints, including the Kuku Pack.
Notable Craftable Items
The following items can be crafted by speaking to Grimnir at the Kilnden Workshop. Each requires specific blueprints and materials.
Item | Description | How to Unlock |
|---|---|---|
Storage device with 230 slots for Abyss objects, machine parts, and contraptions. | Complete kiln repairs in Chapter 4. | |
Base pack unit that is a prerequisite for the Kuku Rocket Pack. | Complete the Sanctum of Penitence during the Witch of Wisdom faction quest. | |
Jetpack that allows Oongka to fly. Consumes stamina while airborne. | Examine the "Letter from Grimnir" obtained from his assistant in Pailune. | |
A small mech contraption built from a Kuku Iron Pot. Retains all stored items from the pot used in its creation. | Unlocked through story progression. | |
Mecha armor for the Blackstar Dragon. Built from a Small Kuku ATAG. | Unlocked through late-game story progression. |
Kuku Rocket Pack Blueprint
After the player progresses past the Sanctum of Penitence in the Witch of Wisdom faction quest line, Grimnir sends a letter through his assistant. The assistant approaches the player on the south side of Pailune and hands over a document titled "Letter from Grimnir." The player must open their inventory and select Examine on the letter to unlock Blueprint II: Kuku Rocket Pack. The crafting recipe will not appear in the Knowledge tab unless this examination step is performed.
Crafting Materials
Assembling the Kuku Rocket Pack at the Kilnden Workshop requires the following materials:
Material | Quantity |
|---|---|
1 | |
10 | |
10 | |
5 | |
3 |
Once assembled, the Kuku Rocket Pack allows Oongka to fly around the open world. Flight consumes stamina, and Oongka drops the moment his stamina reaches zero. Players can extend flight duration by boosting stamina through Abyss Artifacts.
Personality
Grimnir is proud and stubborn. When Kliff first arrives at the Kilnden Workshop and questions him, Grimnir responds with dismissive remarks. He clearly needs help repairing the kilns but refuses to ask for it outright. Despite this prickly exterior, his skills as a craftsman are undeniable. He restored an ancient Kuku Pot from nothing more than a memory fragment, a feat that demonstrates both his technical knowledge and his deep understanding of ancient dwarven engineering.
His relationship with the player evolves over time. After the initial kiln repair quest, Grimnir becomes more cooperative, eventually sending his assistant to deliver the Rocket Pack blueprint rather than waiting for the player to return on their own.
Additional Kuku Pots
Players who want extra storage can obtain additional Kuku Iron Pots by dispatching a mission from the Greymane Camp to the Kilnden Workshop. This is handled through the dispatch system rather than direct interaction with Grimnir.

Patch 1.04: Kuku Cooler Crafting
Patch 1.04 added a new food storage device called the Kuku Cooler, and Grimnir's workshop is the crafting station for both the basic and enhanced versions. The cooler functions like a refrigerator for your personal housing: it stores raw ingredients and cooked dishes, and it behaves as shared storage, so cooking stations anywhere in the world can pull food and ingredients directly from it without requiring you to carry them in your inventory.
The crafting itself follows the same pattern as other Kuku Pot devices produced at the workshop. Once the blueprint is learned, speaking to Grimnir and opening the workshop brings up the Kuku Cooler recipe alongside the existing options. The basic Kuku Cooler holds forty slots of food, which is best used as a dedicated cache of raw cooking materials. The Enhanced Kuku Cooler expands capacity to around three hundred thirty slots, large enough to serve as a full pantry for a well-provisioned personal house.
Because the Kuku Cooler is a Kuku-line device, Grimnir handles its construction personally. He does not delegate this work to his assistants, which fits his established pattern of keeping anything connected to ancient Kuku Pot technology under his own hand. Players who have already completed the earlier Kuku Pot questline will find the crafting interface familiar, though the Kuku Cooler recipe is a separate blueprint and does not share a slot with the Kuku Iron Pot or the Kuku Rocket Pack.
Materials Needed
The Kuku Cooler recipe calls for a specific set of advanced crafting materials on top of the base ingredients the workshop artisan lists on the blueprint sheet. Three materials in particular are worth planning for because they are the hardest to come by during a normal playthrough:
Mercury. A refined material used for the cooler's thermal system. Mercury is not a common drop and is easy to run out of mid-recipe.
Rubber. Used for sealing and insulation. Rubber is often the bottleneck material for the cooler recipe.
Brimstone. Used as part of the refrigeration process. Brimstone is slightly more common than mercury or rubber but still demands deliberate farming.
In addition to the three marquee materials, the blueprint lists the standard base ingredients the workshop artisan shows you when you learn the recipe, such as common ores and basic metal components. The blueprint screen highlights any missing material, and if you are short on something the game points out the nearest farming location on your map.
Outside of drops from exploration and resource nodes, one reliable way to top up mercury, rubber, and brimstone is to visit the trolls at the Scholar Stone Institute. Gifting the troll scholars a hide has a chance to return two units of mercury, rubber, or brimstone in exchange. This is a fast way to supplement farming when you need only a few more units to complete the recipe, and it pairs well with any hunting run you are already doing for Leather or other hide-based materials.
Quest Flow
The Kuku Cooler unlocks through a Hernand faction quest called A Special Blueprint. The quest is filed under the Hernand Requests tab in the faction quest journal, and it becomes available after you have progressed the Hernand questline far enough for the region's workshop network to acknowledge your help. The step-by-step flow is straightforward, but it does pass you between three separate NPCs, so it helps to know the full path before starting.
Step 1: Accept A Special Blueprint. Open the faction quest journal, select the Hernand Requests tab, and accept the new quest. The quest marker sends you to a location just southeast of Hernand, near a farm and village area.
Step 2: Speak to the Hernandian soldier. A Hernandian soldier at the marked location explains that a local artisan has something prepared for you. The soldier points you further west to a workshop artisan stationed near the Kilnden Workshop.
Step 3: Meet the workshop artisan near the Kilnden Workshop. The artisan hands over the blueprint for the basic Kuku Cooler and lists the materials you need. You can review the recipe immediately in your Knowledge tab once you select Examine on the blueprint.
Step 4: Gather the listed materials. Collect mercury, rubber, brimstone, and any base components called for on the recipe sheet. If you are short on a material, the quest marker assists by flagging the nearest known source on the map.
Step 5: Craft at Grimnir's workshop. Return to the Kilnden Workshop, speak to Grimnir, and open the workshop menu. The Kuku Cooler recipe appears alongside the other Kuku-line devices. Confirm the craft and the cooler is produced.
Step 6: Return to the workshop artisan. Take the crafted cooler back to the artisan who issued the original blueprint. After a short exchange, the artisan hands over a second blueprint for the Enhanced Kuku Cooler.
Step 7: Craft the Enhanced Kuku Cooler. Learn the enhanced blueprint, gather the higher-tier materials it requires (expect larger quantities of mercury, rubber, and brimstone, plus stronger base components), and return to Grimnir's workshop to craft the upgraded version. The enhanced cooler is also produced here, not at any other station.
Step 8: Place the cooler in your personal house. Carry the finished cooler back to your Personal Housing plot and place it in an available slot. Once placed, you can deposit raw ingredients and cooked dishes, and any cooking station in the world can pull from its inventory.
Grimnir himself does not react to the cooler beyond letting you run the recipe at the workshop, but the artisan NPC who issues the blueprint treats the hand-in as a genuine proof-of-work. The enhanced blueprint is only issued after you physically bring a completed basic Kuku Cooler back for inspection. If you skip the return trip, the enhanced recipe stays locked even if your inventory already meets the material requirements, so the hand-in step cannot be bypassed.
