Genshin Impact continues to expand its roster with highly specialized support characters, and Illuga fits squarely into that design philosophy. Much like other niche 4-star supports, Illuga is not meant to steal the spotlight—but when paired with the right carry, his buffs and utility can significantly elevate team performance.

While your main priority will usually be maximizing Illuga’s partnered 5-star (most notably Zibai), fully upgrading Illuga is still important. Several parts of his kit scale directly with his level and talents, meaning underinvesting in him can leave noticeable performance on the table. This guide breaks down all Illuga ascension and talent materials, upgrade priorities, and farming tips so you can plan efficiently.

Illuga’s Role and Why Upgrading Him Matters

Illuga is a dedicated support, designed to amplify a specific DPS rather than deal damage himself. His Normal Attacks are largely irrelevant, but his Elemental Skill and Elemental Burst provide scaling buffs that improve as you level him and his talents.

If you plan to use Illuga regularly:

• Ascension increases his base stats and unlocks passive bonuses

• Talent levels improve buff strength and uptime

• Proper investment ensures smoother rotations and better overall damage

Illuga Level-Up Requirements (1–90)

To bring Illuga from level 1 to 90, you’ll need a sizable amount of EXP materials and Mora.

Total Level-Up Costs

• EXP Required: 8,362,650

• Mora Required: 1,673,400

Leveling him fully is recommended if you plan to use him in endgame content such as Spiral Abyss, where every stat matters.

Illuga Ascension Materials Breakdown

To fully ascend Illuga, you’ll need the following materials:

Ascension Gems

• 1× Prithiva Topaz Sliver

• 9× Prithiva Topaz Fragment

• 9× Prithiva Topaz Chunk

• 6× Prithiva Topaz Gemstone

These can be obtained from Geo-aligned bosses or converted using Dust of Azoth.

Enemy Drops (Automaton Enemies)

• 18× Broken Drive Shaft

• 30× Reinforced Drive Shaft

• 36× Precision Drive Shaft

These drops are common from mechanical enemies and can be converted upward using Alchemy if needed.

Normal Boss Material

• 46× Cyclic Military Kuuvahki Core

This material comes from a specific overworld boss and will be your main time-gated ascension requirement.

Local Specialty

• 168× Pine Amber

Pine Amber is found in Illuga’s native region and respawns every 48 hours. Marking routes on your map will save a lot of time.

Mora Cost

• 420,000 Mora (Ascension only)

Illuga Talent Upgrade Priorities

Illuga’s talents do not carry equal importance.

Recommended Priority

1. Elemental Burst – Highest priority (core buffs scale here)

2. Elemental Skill – Optional, but useful

3. Normal Attack – Can safely stay at level 1

Unless you are min-maxing, there’s no reason to invest in his Normal Attacks.

Talent Materials Required (Per Talent)

Talent Books (Elysium Series)

• Teachings of Elysium

• Guide to Elysium

• Philosophies of Elysium

These are obtained from the Elysium talent domain on its scheduled days.

Enemy Drops

• Broken Drive Shaft

• Reinforced Drive Shaft

• Precision Drive Shaft

Weekly Boss Material

• Eroded Horn

You’ll need to challenge a weekly boss consistently, as this is a major bottleneck for higher talent levels.

Crowns

• Crown of Insight (for level 10 only)

Mora Costs

• 1 Talent (1→10): 1,652,500 Mora

• 2 Talents: 3,305,000 Mora

• All 3 Talents: 4,957,500 Mora

Most players should stop after upgrading Burst + Skill, saving Crowns and Mora for other characters.

Farming Tips to Save Time

• Farm Drive Shafts early while doing daily commissions

• Stockpile Pine Amber every respawn cycle

• Use Dream Solvent to convert weekly boss drops if needed

• Prioritize talent domains only on the correct days

Planning ahead prevents resin waste and delays.

Want to Speed Things Up?

Illuga’s upgrade path involves boss farming, weekly drops, local specialties, and talent domains, all of which take time. If you’re short on resin or want Illuga battle-ready quickly, Genshin Impact Boosting at GladiatorBoost can help. GladiatorBoost assists with character leveling, material farming, and talent upgrades—ideal for players preparing teams for Spiral Abyss or future content without weeks of grinding.

Final Thoughts: Is Illuga Worth Fully Building?

Illuga may not be a flashy DPS, but in the right team, he is an exceptional support. Fully ascending him and upgrading his key talents ensures:

• Stronger buffs

• More consistent rotations

• Better synergy with his intended carry

If you’ve already invested in his partnered DPS, giving Illuga proper attention is absolutely worth it.
