To add perks to the Mining Knuckle Drill in Crimson Desert , you don’t “add perks” in the traditional sense—you upgrade the drill to increase its mining bonus (chance to mine extra ore) and improve its stats. The drill’s main perk is a chance to get additional ores, and that chance scales with refinement level.

Quick answer

  • The Mining Knuckle Drill starts with a 10% chance to mine extra ore.
  • By refining/upgrading it, this chance increases up to 30% at max level.
  • There are no separate “perk slots”; the perk is the upgrade itself.

How to get the Mining Knuckle Drill

You can obtain it in two main ways:

  1. From Bleed Bandits in Karin Quarry
    • Some Bleed Bandits wield the drill.
    • Block their attack normally (do not parry), then hit them; they will drop the drill for you to loot.
 * Use a small shield and quick follow-up attack for a more reliable drop.
  1. As a quest reward (Marni’s Excavatron)
    • Progress the House Roberts faction questline in Orgrimmar until you get the “Stolen Quarry” mission.
 * Go to the quarry, defeat the boss **Marni’s Excavatron / X Khav’arr Trom** , and you’ll receive the Mining Knuckle Drill.

How to upgrade / “add perks” to the drill

The drill’s perk (extra ore chance) is tied to its refinement level :

  1. Collect multiple Knuckle Drills
    • Disarm and loot more drills from Bleed Bandits in Karin Quarry or other quarries if available.
 * You can also reuse the drop method (block → attack) to get more.
  1. Refine the drill at the Smithy
    • Take your primary drill and the duplicate drills to the smithy.
    • Use the duplicates to refine the main drill, increasing its level.
 * Each refine level increases the extra-ore chance and other stats.
  1. Upgrade stats and chance
    • At level 6 , you get around 20% extra ore chance.
 * At **level 10 / max** , you reach the full **30%** chance.

 * Upgrading requires:
   * Iron ore
   * Copper ore
   * Blood stone
   * Abyss artifact

(exact materials may vary by patch, but these are the listed requirements).

How to use the drill

Once you have and upgraded the drill:

  1. Equip the Mining Knuckle Drill in your weapon slot.
  2. Go to any ore node (iron, copper, etc.).
  3. Hold L1 (target/lock) and press R1 to drill.
 * The drill will automatically break the deposit and **collect ores**.
 * You also get the **chance-based extra ore** based on your current refinement level.

Why this is the “perk” system

  • The drill doesn’t have separate perk selections or mod slots.
  • Its main “perk” is the mine-extra-ore chance , which is purely a function of refinement level.
  • So “adding perks” = refining and upgrading the drill as much as you can.

Bottom-line procedure:
Get multiple Knuckle Drills → refine at the smithy using duplicates → upgrade to max level with ores + blood stones + abyss artifacts → equip and use L1+R1 on ore nodes to get up to 30% extra ore. Information gathered from public forums or data available on the internet and portrayed here.
