What to know
- Oilstone requires the Impact Hammer to mine.
- The Impact Hammer blueprint is sold by Zerine after reaching Junior Crafting Rank.
- The main Oilstone spawn is in a cave at Harvest Yard Camp in Moonlight Forest.
- You must pass the bronze gate and clear vine barriers to reach the area.
If you are progressing through Starsand Island and starting to craft more advanced gear, you will quickly notice that Oilstone becomes a core crafting resource. It is used in several mid-tier crafting recipes, especially those tied to mechanical upgrades and enhanced tools. While the material is not available early in the game, once unlocked, it becomes one of the most farmable mineral nodes if you know the exact route.
Below is a quick overview to help you understand the full process at a glance before diving into the details.
| Requirement | Details |
|---|---|
| Tool Needed | Impact Hammer |
| Blueprint Seller | Zaren (General Store) |
| Unlock Condition | Junior Crafting Rank |
| Main Location | Harvest Yard Camp, Moonlight Forest |
| Area Access | Bronze gate unlocked + vines cleared |
| Best Farming Spot | Cave inside Harvest Yard Camp |
Once you understand these basics, the process becomes straightforward.
Unlocking the Impact Hammer through Zaren’s crafting progression
The most important step in obtaining Oilstone is unlocking the correct mining tool. Oilstone cannot be mined with basic or bronze-tier tools. You specifically need the Impact Hammer, which is classified as a higher-tier mining tool designed for tougher mineral deposits.
To unlock it, you must increase your crafting progression to Junior Crafting Rank. This is achieved by completing crafting quests given by Zerine at the General Store. Zaren acts as your early-to-mid-game crafting progression NPC, and his quests are designed to gradually push you into better materials and systems.
As you complete his crafting tasks, your crafting rank increases. Once you hit Junior Crafting Rank, the Impact Hammer blueprint becomes available for purchase in his shop inventory. After buying the blueprint, you must craft the Impact Hammer at the appropriate crafting station using the required materials.
This progression gate is intentional. Oilstone is meant to be a mid-tier resource, so the game ensures you are prepared before accessing it.
Reaching Harvest Yard Camp in Moonlight Forest
Once you have the Impact Hammer crafted and ready, your next objective is reaching Harvest Yard Camp inside Moonlight Forest. This region is not immediately accessible in the early stages of the game.
To enter Moonlight Forest, you must first unlock the bronze gate that blocks access to the area. This typically involves completing story or progression tasks tied to exploration and quest advancement. After passing through the bronze gate, you will encounter vine barriers that block certain pathways deeper into the forest.
The recommended method for clearing these vines is using fire arrows, which burn the obstruction and permanently open the route. Without clearing these vine barriers, you will not be able to reach Harvest Yard Camp efficiently.
Moonlight Forest itself is denser, darker, and more resource-rich compared to early biomes. Expect stronger enemies and more complex terrain. Bringing healing items and adequate gear is strongly recommended before heading deeper into this zone.
Finding the Oilstone cave inside Harvest Yard Camp
Once you arrive at Harvest Yard Camp, you are very close to your primary Oilstone source. The key resource node is located inside a specific cave within the camp area.
This cave contains an abundant and concentrated spawn of Oilstone deposits, making it the most efficient early farming spot for this material. The deposits appear as distinct mineral nodes embedded in the cave walls and floor. With the Impact Hammer equipped, you can mine these nodes directly.
While Oilstone can also be found deeper inside Moonlight Forest, the cave at Harvest Yard Camp is considered the most reliable and concentrated spawn point. For consistent farming runs, this cave should be your main target location.
Because cave interiors often have tighter enemy spawns, it is advisable to clear nearby hostiles first. Once cleared, you can safely farm multiple Oilstone nodes in a single run before respawn timers reset.
Oilstone farming efficiency and respawn behavior
Oilstone nodes respawn over time, making the Harvest Yard Camp cave a renewable resource location. Efficient farming involves clearing the cave, mining all nodes, exiting the area, and returning after sufficient in-game time has passed.
If you are planning extended crafting sessions, you can combine Oilstone farming with other Moonlight Forest materials to maximize each run. The deeper forest zones contain additional rare resources, so advanced players often chain resource farming routes instead of focusing on a single node type.
The cave’s advantage lies in its high node density relative to travel time, which minimizes downtime between mining sessions. Compared to scattered nodes deeper in the forest, this cave remains the most practical and repeatable Oilstone farming location.
Why Oilstone matters in mid-game progression
Oilstone becomes increasingly important as you transition into stronger gear tiers. It is commonly required for enhanced crafting components, mechanical upgrades, and higher-tier crafting station improvements. Without a steady supply of Oilstone, your progression can slow significantly.
This is why unlocking the Impact Hammer early at Junior Crafting Rank is strategically beneficial. The earlier you secure reliable Oilstone access, the smoother your mid-game crafting experience becomes.
Players who delay this step often find themselves bottlenecked when attempting to upgrade equipment or unlock new crafting tiers.
Practical preparation before farming Oilstone
Before heading to Harvest Yard Camp, make sure you are adequately prepared. Since Moonlight Forest contains stronger enemies than starter regions, ensure you bring durable armor, sufficient healing items, and ranged options like fire arrows for clearing vine barriers or managing hostile encounters.
Your Impact Hammer should also be in good durability condition before entering the cave, as multiple Oilstone nodes can quickly reduce tool durability during extended farming sessions.
If you plan to make repeated runs, consider setting up a nearby fast travel point or camp location to reduce travel time.
