Mining Knuckledrill Guide
The Mining Knuckledrill is a dual-purpose piece of special equipment in Crimson Desert that functions as both a one-handed weapon and a high-efficiency mining tool. It is obtained by defeating Marni's Excavatron during the Stolen Quarry faction quest for House Roberts. Thanks to its Mining Mastery effect, which grants a 10% chance to yield additional ore from every node, the Knuckledrill is one of the most valuable tools available during the early and mid stages of the game.
This guide covers everything you need to know: the quest chain that leads to the Knuckledrill, a full breakdown of the Marni's Excavatron boss encounter, the weapon's stats and mining bonuses, upgrade details, and practical tips for getting the most out of it.
Weapon Stats
The Mining Knuckledrill is classified as a one-handed weapon and can be equipped in the secondary weapon slot. While its raw attack power is modest compared to dedicated combat weapons, its real value lies in the Mining Mastery passive and its faster drilling speed when gathering ore.
Stat | Value |
|---|---|
Type | One-Handed Weapon |
Attack | 15 |
Attack Speed | Normal |
Weight | 4 |
Core Slots | 5 |
Critical Chance | +1 |
Special Effect | Mining Mastery (10% chance to mine additional ores) |
Refinement Cap | 10 |
Slot | Secondary Weapon |
The five Abyss Core slots give you room to socket cores that complement your playstyle. Since the Knuckledrill is primarily a utility tool, consider equipping cores that boost gathering speed or survivability rather than raw damage.
How to Unlock the Mining Knuckledrill
The Knuckledrill is a guaranteed reward for completing the Stolen Quarry quest, the final step in a short faction questline for House Roberts. This questline becomes available during Chapter 2 and takes place in the Hernand region.
Required Quest Chain
You must complete the following quests in order. All three are part of the House Roberts Quests faction storyline.
Step | Quest | Summary |
|---|---|---|
1 | Introductory faction quest near Blummont Manor. Involves NPC interactions and learning about House Roberts. | |
2 | Short follow-up quest with dialogue inside Blummont Manor. Straightforward and quick to finish. | |
3 | Travel to Karin Quarry, clear Bleed Bandits, and defeat Marni's Excavatron. Rewards the Mining Knuckledrill and a Gold Vein Map. |
Location
The boss arena is inside Karin Quarry, a mining site that has been occupied by the Bleed Bandits. To reach it, head northeast from the City of Hernand toward Goldenleaf Trading Post. From the trading post, go north up the hill into the quarry. You will encounter Bleed Bandit enemies along the way before arriving at the Excavatron's arena.
Marni's Excavatron Boss Fight
Marni's Excavatron is a mechanical mining machine that the Bleed Bandits have repurposed for their operations in Karin Quarry. It attacks using its twin drills and can burrow underground to pursue Kliff from below. The fight is not overly difficult if you understand its patterns, but carelessness can get you killed quickly.
Attack Patterns
Attack | Description | How to Counter |
|---|---|---|
Drill Charge | The Excavatron winds up its drills and thrusts forward in a straight line. Deals heavy damage and drains significant stamina if blocked. | Sidestep rather than block. The charge travels in a straight path, so stepping laterally avoids it entirely. |
Dig (Underground Phase) | Both drills light up before the boss burrows underground. It follows your position and stabs upward repeatedly, then resurfaces with a heavy slam. | Sprint to avoid the underground stabs, then dodge just before the final resurface attack. Force Palm or Blinding Flash can interrupt the dig entirely. |
Powered-Up Dig | When low on health, the Excavatron enters a powered-up state. Its underground phase now includes three stab sequences before it resurfaces. The damage is significantly higher and can one-shot unprepared players. | Dodge immediately after the second underground hit to avoid the lethal third strike. Keep your health topped off going into the later phase of the fight. |
Rapid Drill Swipes | Close-range flurry of drill strikes that can stun-lock you if the first hit connects. Comes out fast with little warning. | Maintain safe distance and only commit to melee during confirmed stagger windows. Use a shield to block if caught up close. |
Recommended Strategy: Force Palm Loop
The most reliable way to beat Marni's Excavatron is the Force Palm loop. Before attempting this fight, unlock Level 3 Force Palm and invest in the Force Palm Expertise node on the skill tree. This allows you to chain three consecutive Force Palms, and the third strike produces a distinct sound and staggers the Excavatron, opening a damage window.
Close the distance and land three consecutive Force Palm strikes. The third hit stuns the boss.
Execute a full melee combo while the Excavatron is staggered.
Retreat to a safe distance before it recovers.
Activate Focus to regenerate your Spirit, then repeat the cycle.
Each Force Palm costs 5 Spirit per use, so managing your Spirit bar is essential. The Focus ability provides on-demand Spirit regeneration between attack cycles.
Alternative Strategy: Blinding Flash
If the Excavatron begins its Dig animation (both drills light up), you can activate Blinding Flash (L1 + R1 on controller) to short-circuit and stun the machine. This interrupts the underground phase entirely and creates a safe opening for damage. This technique is especially useful during the powered-up version of the Dig, which is the boss's most dangerous move.
Managing the Bleed Bandits
Several Bleed Bandit enemies occupy the arena alongside the Excavatron. The optimal approach is to kill two of them and leave the third alive. The game spawns additional bandits when all of them are eliminated, so keeping one alive prevents reinforcement waves while keeping the threat level manageable. Focus your attention on the boss and only deal with bandits if they are directly interfering with your positioning.
Preparation Checklist
Level 3 Force Palm with the Expertise node unlocked (highly recommended).
Sword and shield equipped for blocking when caught in close quarters.
Focus ability unlocked for Spirit regeneration.
Upgrade your armor at a blacksmith before the fight to improve survivability.
Bring healing food items to sustain through the powered-up phase.
Rewards
Defeating Marni's Excavatron completes the Stolen Quarry quest and grants two rewards.
Reward | Description |
|---|---|
Dual-purpose one-handed weapon with Mining Mastery effect. Mines ore faster than a standard pickaxe and grants a 10% chance for bonus ore. | |
Reveals the locations of gold ore caves on your map. Consuming the map marks these deposits, making it much easier to farm gold ore for crafting gold bars. |
Mining Efficiency
The Knuckledrill's Mining Mastery effect is what sets it apart from a standard pickaxe. When mining ore nodes, the Knuckledrill works faster and gives a flat 10% chance to receive additional ore from each strike. Over the course of a long farming session, this bonus adds up significantly.
Knuckledrill vs. Pickaxe
Feature | Pickaxe | Mining Knuckledrill |
|---|---|---|
Mining Speed | Standard | Faster |
Bonus Ore Chance | None | 10% (increases with refinement) |
Combat Use | None | Yes (one-handed weapon) |
How to Obtain | Rhett's Request (free) or shops | Stolen Quarry quest reward |
Weapon Slot | N/A | Secondary |
Because the Knuckledrill occupies the secondary weapon slot, you can keep your primary combat weapon equipped and switch to the Knuckledrill whenever you spot an ore deposit. There is no need to open your inventory to swap tools.
Best Ore Nodes to Farm
Once you have the Knuckledrill and the Gold Vein Map, prioritize visiting the gold ore caves it reveals. For standard materials, the best mining locations in the Hernand region include Karin Quarry itself (which you have already cleared of bandits), as well as various cave systems throughout the Hernand Highlands. Key ores to target include Iron Ore and Copper Ore, both of which are used in gear refinement at the blacksmith.
Ore nodes respawn after a few in-game days. If you want to speed up respawning, you can save your progress, exit to the main menu, and reload. The mining spots will be immediately available again.
Using the Knuckledrill in Combat
While the Knuckledrill's attack power of 15 puts it behind most dedicated weapons in terms of raw damage, it has a unique combat moveset. Holding the basic attack button causes Kliff to thrust the Knuckledrill forward in a continuous drilling motion that hits the targeted enemy repeatedly. After several seconds of sustained contact, a finishing move triggers automatically, knocking the enemy backward.
This moveset works best against single, slower enemies where you can safely commit to the sustained drilling animation. Against groups or fast-moving opponents, you are better off switching to your primary weapon.
Special Equipment Challenge
The Knuckledrill has an associated Special Equipment Challenge under the Mastery category. The challenge requires you to hit enemies with the explosion from the overheated Knuckledrill 5 times.
How to Complete the Overheat Challenge
When you hold the basic attack with the Knuckledrill for an extended duration, the tool overheats and produces an explosive finishing move. The challenge tracks each time this explosion connects with an enemy. To complete it efficiently, find a group of weaker enemies (bandits work well) and hold the attack button until the finishing explosion triggers. Repeat five times total.

Completing all 10 Special Equipment Challenges unlocks the Grand Collector of Arms achievement.
Refinement and Upgrades
Like other equipment in Crimson Desert, the Mining Knuckledrill can be upgraded through the refinement system. Visit a blacksmith and select the Refinement option to improve the weapon's stats. Refinement increases the Knuckledrill's attack power and can improve its mining bonus at higher levels.
Refinement Levels 1 to 4: Require standard materials (Iron Ore, Copper Ore) and no special currency.
Refinement Levels 5 and above: Require Abyss Artifacts in addition to ore materials. Farm Abyss Artifacts from dungeons and sealed artifact puzzles.
Maximum Refinement: Level 10. Each level provides incremental stat boosts.
For a full list of materials needed at each refinement tier, see the Refinement and Upgrade Materials article.
Tips and Tricks
Get it early. The House Roberts questline becomes available in Chapter 2. Completing it as soon as possible means you benefit from the Mining Mastery bonus for the rest of the game.
Keep it in your secondary slot. Since the Knuckledrill goes in the secondary weapon slot, there is no trade-off with your primary combat weapon. You can switch to it instantly whenever you spot mineable ore.
Pair with the Gold Vein Map. The map and the Knuckledrill come from the same quest. Use the map to locate gold ore caves, then mine them with the Knuckledrill for maximum gold yield.
Use Focus before Force Palm cycles. During the Excavatron fight, always top off your Spirit with Focus before going in for another Force Palm loop. Running out of Spirit mid-combo leaves you vulnerable.
Do not kill all the Bleed Bandits. In the boss arena, leave at least one bandit alive. Killing all of them triggers a reinforcement wave, which adds unnecessary pressure during the Excavatron fight.
Save and reload for ore respawns. After clearing a mining area, save your game, exit to the main menu, and reload. The ore nodes reset immediately, letting you farm continuously.
Invest in refinement. Even a few levels of refinement make a noticeable difference in attack power. Since the Knuckledrill's ore requirements are low-tier, upgrading it early is cost-effective.
Recover a sold Knuckledrill. If you accidentally sell the Knuckledrill, you may be able to buy it back from the vendor you sold it to. Alternatively, Bleed Bandit enemies in Karin Quarry have a small chance to drop one.
