Complete guide to pre-farming Illuga’s ascension materials with strategic farming tips and optimization methods
Illuga’s Complete Ascension Material Requirements

Recent leaks surrounding Genshin Impact’s upcoming Luna IV update suggest Illuga will debut as a new 4-star character. Multiple reliable sources including HomDGCat and Hiragara have provided detailed information about his potential abilities, constellations, and the specific materials needed for his ascension progression.
To fully upgrade Illuga to level 90 and maximize all three talents to level 10 (triple-crowning), you’ll need to gather the following materials:
- 36 Broken Drive Shaft
- 96 Reinforced Drive Shaft
- 129 Precision Drive Shaft
- 1 Prithiva Topaz Sliver
- 9 Prithiva Topaz Fragment
- 9 Prithiva Topaz Chunk
- 6 Prithiva Topaz Gemstone
- 46 Cyclic Military Kuuvahki Core
- 9 Teachings of Elysium
- 114 Philosophies of Elysium
With the exception of Pine Amber, the regional specialty item expected to release with the new map expansion in Luna IV, all other materials can be pre-farmed immediately. Strategic planning now will significantly reduce the time investment required once Illuga becomes available.
Boss Materials Farming Locations
The Super-Heavy Landrover: Mechanized Fortress boss, introduced during the Luna III update, serves as the primary source for Cyclic Military Kuuvahki Cores. This challenging encounter requires strategic team compositions featuring shielders and healers to manage its powerful area-of-effect attacks.
For Prithiva Topaz ascension gems, focus your farming efforts on these specific world bosses:
- “Statue of Marble and Brass” – Recommended for teams with strong geo characters
- Experimental Field Generator – Vulnerable to cryo and hydro element combinations
- Perpetual Mechanical Array – Efficient for co-op farming with friends
The various Drive Shaft materials drop exclusively from Landcruiser-type enemies scattered throughout the Nod-Krai region. Higher-tier variants tend to drop better quality materials, so prioritize defeating elite Landcruisers whenever possible. For optimal farming routes, consider starting from the central waypoint and moving counter-clockwise through the region to maximize enemy encounters per run.
Weekly boss materials including Eroded Horns come from defeating the Lord of Eroded Primal Fire. Since these drops are heavily RNG-dependent, consistent weekly clears are essential. Using condensed resin doesn’t affect weekly boss rewards, so focus on optimizing your team composition instead.
Talent Materials Farming Guide
The Lightless Capital domain in Nod-Krai provides access to Elysium talent books, available specifically on Mondays, Thursdays, and Sundays. This scheduling pattern allows for concentrated farming three days per week, making efficient resin management crucial.
For maximum efficiency, consider these domain strategies:
- Use condensed resin during peak farming days to double your material yield
- Bring characters that match the domain’s elemental advantages for faster clear times
- Coordinate with friends for co-op runs to share the resource cost
- Complete the domain during bonus drop events when available
Crown of Insight materials, necessary for talent level 10, primarily come from completing all mini-games in flagship events. Additional sources include special offering systems like the Frostbearing Tree and Sacred Sakura. Since these are limited resources, prioritize using them on your most valuable characters.
Common mistakes to avoid include farming on wrong days, forgetting to use condensed resin, and neglecting to check event schedules for potential bonus periods. Setting in-game reminders for talent book days can significantly improve your farming consistency.
Advanced Farming Optimization
For experienced players looking to maximize resin efficiency, consider these advanced strategies. First, prioritize farming boss materials during days when talent domains aren’t available, creating a balanced weekly farming schedule. The 160 original resin cap means you can typically complete 4-5 boss runs or 8-10 domain runs per day without using fragile resin.
Drop rate enhancement tips include:
- Complete your weekly boss battles after reaching Adventure Rank 45 for guaranteed 5-star artifacts
- Use characters with passive talents that increase material drop rates when available
- Focus on one material type per day to maintain progress momentum
Team composition recommendations vary by content. For Landcruiser farming, bring characters with strong crowd control and area damage. For boss battles, include shielders like Zhongli or healers like Kokomi to survive powerful attacks. Domain runs benefit from characters that counter the specific domain’s elemental shields.
Remember that pre-farming provides a significant head start but requires careful planning. Track your material progress using external tools or spreadsheets to avoid over-farming one material while neglecting others.
