The gem system in Xenoblade Chronicles 3 allows for powerful character customization, enhancing roles like attacking, healing, tanking, and utility support. While the core mechanics are simple, deciding which gems to prioritize and how to farm high-level crafting materials can be tricky. This comprehensive guide breaks down the gem system, evaluates each gem’s value, and shares efficient material farming strategies to help you craft Level 10 gems with ease.

How the Gem System Works

• Crafting Location: Gems are crafted at rest spots and upgraded using specific monster materials.
• Levels: Each gem can be leveled from 1 to 10, offering stronger effects at higher tiers.
• Slots: Every character can equip up to three gems.
• Shared Use: Once crafted, a gem can be equipped by multiple characters at the same time—no duplicates needed.
• Gem Types: There are four main categories: Tanking, Attack, Healing, and Utility.

How to Efficiently Farm Gem Materials

🔑 Key Strategies

1. Cook Drop-Rate Boosting Meals
   • Meals like Rich Stew or Fruity Rice increase material drops. Prepare them at camps before hunting.
2. Focus on Burst Combos
   • Use Break → Topple → Daze → Burst to farm specific materials from enemies.
   • Burst prevents Overkill, keeping enemies alive longer to drop more loot.
3. Fight Unique and Elite Monsters
   • These enemies drop higher-tier materials and respawn easily.
   • Avoid Smash combos, as they lower material drop rates.
4. Pin Materials in the Crafting Menu
   • Press the “+” button to pin required materials for each gem.
   • Use the tracking system to locate monsters that drop the needed items.

🛠️ Ideal Farming Setup

• Party Setup:
  • Include at least one Break, Topple, Daze, and Burst user.
  • Use Soulhacker or War Medic for versatile burst combos.
• Accessory Suggestions:
  • Break Brooch – Boosts Break success rate.
  • Daze Charm – Extends Daze duration.
  • Burst Amulet – Speeds up Talent Arts to trigger burst more often.
• Best Farming Zones:
  • Any high-level zone with elite monster clusters (e.g., Cadensia Region, Upper Aetia).

---

Final Tips

• Craft High-Impact Gems First: Prioritize Empowered Combo, Critical Damage Boost, and Buff Duration Boost.
• Always Use Reusable Gems: Since gems are shared across characters, one Level 10 gem benefits your whole roster.
• Farm Smart, Not Hard: Focus on elite enemies near campsites with good drop rates, and optimize your combo and meal setups.
