Illuga represents the newest 4-star addition to Genshin Impact’s roster, scheduled for release during the Luna IV update. As a Geo element character, he specializes in off-field sub-DPS and support roles, making him valuable for teams requiring sustained elemental application and defensive capabilities. Illuga is anticipated to join the Lightkeeper faction, following Flins as the second playable member from this group. For travelers planning to acquire Illuga when Luna IV launches, beginning your material farming preparations now will ensure you can maximize his potential immediately upon release.
Pro Tip: Since Illuga functions as an off-field support, prioritize talent upgrades that enhance his elemental skill duration and damage multipliers, as these will provide the most significant combat benefits for your team composition.
Full List of Illuga Ascension and Talent Materials Leaked
Here is the total number of Illuga ascension materials in Genshin Impact:
- Prithiva Topaz Silver: 1
- Prithiva Topaz Fragment: 9
- Prithiva Topaz Chunk: 9
- Prithiva Topaz Gemstone: 6
- Pine Amber: 168
- Broken Drive Shaft: 18
- Reinforced Drive Shaft: 30
- Precision Drive Shaft: 36
- Cyclic Military Kuuvahki Core: 46
- Mora: 420,000
Material Analysis: The Prithiva Topaz gemstone progression follows the standard pattern for Geo characters, requiring careful farming of Geo Hypostasis or other Prithiva Topaz-dropping bosses. Pine Amber stands out as the only material currently unavailable for farming, making it the primary bottleneck for immediate ascension upon Illuga’s release. The Drive Shaft material group demonstrates a tiered progression system typical of enemy drop materials, with higher quantities needed for advanced tiers.
Common Mistake: Many players underestimate the time investment required for local specialty collection. Pine Amber’s 168 requirement means you’ll need to dedicate approximately 3-4 dedicated farming sessions across the new Luna IV map areas to gather sufficient quantities.
Here are the total number of Illuga talent materials in Genshin Impact:
- Broken Drive Shaft: 6
- Reinforced Drive Shaft: 22
- Precision Drive Shaft: 31
- Teachings of Elysium: 3
- Guide to Elysium: 21
- Philosophies of Elysium: 38
- Eroded Horn: 6
- Crown of Insight: 1
- Mora: 1,653,000

Talent Upgrade Strategy: The Books of Elysium follow the standard talent book progression, with Philosophies requiring the most significant investment. Note that talent upgrades consume substantially more Mora than character ascension, totaling over 1.6 million for maximum investment. The single Crown of Insight represents the typical limitation for talent maximization, requiring careful consideration of which talents to prioritize for crowning.
Resource Planning: For optimal resin efficiency, schedule your Lightless Capital Domain runs specifically on Tuesday, Friday, and Sunday when Elysium books are available. This focused approach can reduce your farming time by 30-40% compared to random domain attempts.
How to Farm for Illuga Materials in Genshin Impact
1. Pine Amber
Pine Amber is a new material that can be farmed in the Genshin Impact Luna IV’s new map. Until then, you can pre-farm the other materials listed.
2. Drive Shaft Material Group

The Drive Shaft material group can be found by defeating Landcruisers. You will encounter this enemy throughout Nod-Krai, primarily in areas with numerous Automatons. Use the Enemy section in the Adventurer’s Guide to track Landcruisers and defeat them.
3. Books of Elysium

The books of Elysium can be farmed from the Lightless Capital Domain in Lempo Isle. You can farm this item on Tuesday, Friday, and Sunday.
4. Cyclic Military Kuuvahki Core

Cyclic Military Kuuvahki Core is dropped by Super-Heavy Landrover Mechanized Fortress. You will find this boss in the Kuuvahki Experimental Design Bureau.
5. Eroded Horn

Eroded Horn can be obtained by defeating the Lord of Eroded Primal Fire boss. You can fight this enemy by challenging the Lord of Eroded Primal Fire Trounce Domain in Natlan.
Advanced Farming Technique: For Landcruiser farming, bring characters with strong AoE capabilities and elemental reactions that can quickly break through their mechanical defenses. Electro and Pyro characters typically perform well against these enemies.
Resin Optimization Strategy: Plan your farming sessions around the specific days when materials are available. For Books of Elysium, focus your resin usage exclusively on Tuesday, Friday, and Sunday to maximize efficiency. Use condensed resin for domain runs to double your rewards per run, saving valuable time while maintaining material acquisition rates.
Common Pitfall: Many players waste resin farming bosses multiple times daily without considering the weekly reset schedules. The Super-Heavy Landrover Mechanized Fortress and Lord of Eroded Primal Fire both follow weekly reset patterns, meaning you can only collect their valuable drops once per week. Plan your boss fights strategically around your weekly schedule.
Material Conversion Advantage: Remember that you can convert lower-tier materials into higher-tier ones using the alchemy table, but this comes at an exchange rate penalty. It’s always more resin-efficient to farm the appropriate world level for direct higher-tier material drops rather than relying on conversion.
Team Building Insight: When preparing teams for material farming, consider that Illuga’s Geo element makes him particularly effective against Geo constructs and shielded enemies. For comprehensive character building strategies, check our Class Guide for optimal party compositions.
So, these are the materials for Illuga in Genshin Impact. You can farm almost all the materials for Illuga in Nod-Krai. So start farming if you want to build Illuga in Genshin Impact Luna IV.
