Illuga
Who is Illuga?
Illuga is a 4★ Geo Polearm Support from Nod-Krai's Lightkeepers faction, rated S-tier Support by Game8. He is a niche but powerful enabler for Lunar-Crystallize teams: his Burst buffs Geo and Lunar-Crystallize DMG based on his EM, his A1 passive buffs party Geo CRIT stats, and he sheds enemy DEF on Geo reactions. Restricted to Zibai + Columbina teams for full value, but within that niche he is a key piece. Source: https://game8.co/games/Genshin-Impact/archives/555902

よくある質問
Is Illuga useful without Zibai?
Limited — his Burst buffs Geo/Lunar-Crystallize DMG specifically. Without Lunar-Crystallize enablers (Columbina + Zibai), his role shrinks to a basic Geo support. Source: Game8.
What EM should Illuga target?
750+ Elemental Mastery — his Burst buff scales with EM, and his A1 EM scaling also contributes. Source: Game8.
What is Illuga's best constellation?
C2 — it summons Aedon for off-field damage when Burst stacks are consumed, enabling artifact set procs and adding meaningful damage. C6 adds significant team CRIT stats. Source: Game8.
Is Illuga a 4-star or 5-star?
4-star — obtainable at normal rates on standard and featured banners after his debut. Source: Game8.
