How To Get Sharpening Gizmo in Diablo 4 Season 9

By Daniel Hidalgo | 2025-07-17 08:48:12
Diablo 4 Season 9 continues to deliver exciting new content for spellcasters, introducing powerful Arcanas and Infusions to enhance your builds. Among the latest additions, the Sharpening Gizmo stands out as a must-have Arcana for any spell-focused player. This guide will explain why it’s so valuable and how to farm it efficiently.

Why the Sharpening Gizmo is a Game-Changer


The Sharpening Gizmo is a Magic-tier Arcana that significantly boosts your Catalyst’s critical hit potential. Here’s what it does:
  • +50% chance for Catalyst critical hits
  • Deals 200-340% Physical damage on crit
  • Doubles your Catalyst’s Lucky Hit Chance

With these buffs, spell-based builds gain massive damage potential, making this one of the best Arcanas in Season 9. While RNG still plays a role, the Sharpening Gizmo’s high crit chance makes it a top-tier pick for maximizing DPS.

How to Farm the Sharpening Gizmo in Diablo 4


Unlike some gear that can be crafted or purchased, the Sharpening Gizmo is exclusive to Horadric Strongrooms, special endgame dungeons with high-tier rewards. Here’s how to get it:

Step 1: Unlock Nightmare Dungeons


  • Obtain Nightmare Sigils (from endgame activities like Helltides or World Bosses).
  • Use a Nightmare Sigil to open a Nightmare Dungeon.

Step 2: Locate the Horadric Strongroom


  • Progress through the dungeon, clearing enemies.
  • Use the Horadric Wayfinder (a special item) to detect the Horadric Gateway.
  • Interact with the gateway to enter the Horadric Strongroom.

Step 3: Farm Attunement for Better Rewards


  • Defeat enemies inside the Strongroom to earn Attunement.
  • Higher Attunement increases your loot quality and drop chances.
  • The final boss drops a Horadric Cache, which has a chance to contain the Sharpening Gizmo.

Optimizing Your Farm


  • Group Play: Teaming up speeds up clears and improves loot efficiency.
  • Higher World Tiers: Playing on World Tier 3 or 4 increases Magic+ drop rates.
  • Repeat Runs: Since drops are RNG-based, multiple attempts may be needed.

Best Builds for the Sharpening Gizmo


This Arcana shines in high-crit spell builds, such as:


  • Sorcerer (Chain Lightning/Ice Shards builds)
  • Necromancer (Bone Spear/Blood Surge setups)
  • Druid (Storm/Companion hybrids)


Pair it with Lucky Hit gear and Critical Strike Damage modifiers for maximum effect.

Final Thoughts


The Sharpening Gizmo is one of Diablo 4 Season 9’s strongest Arcanas, making it essential for spellcasters. While farming it requires patience, the damage boost it provides is well worth the effort.
