Illuga Best Build Overview
Illuga’s entire kit is tailored for off-field Geo support. His primary value comes from amplifying Lunar-Crystallize DMG and buffing party members, especially in Zibai-centric teams and reaction-driven lineups. A well-optimized Illuga enables substantial DPS gains for Geo carries, notably Zibai, Arataki Itto, and (depending on comp) even Noelle, when capitalizing on Lunar triggers.
Best Weapons
- Favonius Lance (4★): Essential for Energy Recharge, enabling near-permanent Burst uptime and providing team battery utility. Remains the top choice for both F2P/low-spend and meta-optimized builds, as Illuga’s value scales with burst frequency.
- Dragon’s Bane (4★): When Energy Recharge is already sufficient, the high Elemental Mastery (EM) stat substantially boosts Illuga’s reaction buffs. Good in team settings where Illuga is fully supported, but requires careful ER management.
No signature 5★ polearm available for Illuga as of patch 6.3 — subject to change in future cycles.
Optimal Artifact Set
| Set Name | Notes |
|---|---|
| 4pc Aubade of Morningstar and Moon | BiS. Grants +80 EM (2pc) and up to +60% Lunar reaction DMG for off-field supports. |
- Main Stats: Timepiece (Energy Recharge), Goblet (Elemental Mastery), Circlet (Elemental Mastery)
- Substats (Priority): Elemental Mastery > Energy Recharge
Note: The Aubade set only requires Illuga to remain off-field, aligning perfectly with his support design.

Constellation Guide: Value by Tier
As with most supports, Illuga’s constellations are impactful but not strictly required for relevance in endgame content.
| Constellation | Effect (Short) | Priority | Impact |
|---|---|---|---|
| C1 | +12 Elemental Energy after Geo reaction (15s cooldown) | High | Eases ER/stat threshold, smoother rotation |
| C2 | Special Geo burst DMG based on EM and DEF | Medium | Offers personal damage, not core |
| C4 | +200 DEF to active party members with Burst active | High | Further boosts Geo team tankiness |
| C6 | Buffs Lightkeeper’s Oath effect (+10% CR, +30% CD, +80 EM) | Priority | Dramatic spike to all Geo DPS while buff is active |
F2P/low-spend: C1 delivers smoother gameplay and burst rotations, but Illuga is viable at C0.
Core Teams & Synergies
Illuga shines in:
– Zibai Geo Reaction Teams: Enables Lunar-Crystallize chaining, unlocking Zibai’s full carry potential (Zibai team comp guide).
– Mono-Geo Comps: Buffs Itto/Noelle/Albedo teams, stacking DEF and EM for robust, sustained output.
– Flexible Support Slot: Can facilitate double-Geo for resonance + Lunar reactions with third-element enablers.
If running Illuga off-field, priority is maximizing buff uptime and Lunar triggers, not personal damage.
Pull Guidance — F2P, Low-Spend, and Meta Considerations
- F2P/Conservative: If your primary teams do not rely on Geo or Lunar-Crystallize, Illuga is a luxury, not a necessity. Unless you plan to invest in Zibai or Itto, you may want to conserve primogems for upcoming banners (see current Genshin Impact tier list).
- Meta/Geo Mains: Illuga is fundamental for pushing the new reaction-driven Geo teams in patch 6.3 and beyond. If you main Geo or are building toward Zibai/Lunar comps, strongly consider pulling at least C0.
- Competing Banners: Always compare with scheduled reruns. Await full 4★ lineups and overlap info — as of this writing, not yet provided in official disclosures.
- Pity & Dupes: Standard mechanics apply; plan for 70~90 pulls for hard pity, with standard 50-50 on featured banners.
Preparation Checklist: Key Steps Before Banner Launch
- Pre-farm Artifact Set: Target Aubade of Morningstar and Moon domain runs; resin-efficient.
- Ascension Materials: Geo bosses and weekly bosses are rate-limited. Estimate 7–10 days for F2P.
- Talent Books: Track resets. Not stated in official material which domain book applies.
- Teambuilding: Identify current Geo mains. Reserve build slots and weapon investments.

What’s Next for Geo Teams
With Illuga’s introduction, Geo-centric teams gain a crucial new enabler. As the Luna IV patch (6.3) matures, watch for evolving team meta, especially as more information surfaces about Lunar-Crystallize mechanics and future banners. For context, keep up with the full patch analysis and detailed coverage on upcoming banners and team guides at EarlyGG.
Key takeaway: Pull for Illuga if you are committed to Geo or Lunar-Crystallize teams, and ensure you have sufficient Energy Recharge and EM support for best results. Otherwise, primogem conservation may be wiser until the next major meta shift.
