Illuga is a highly anticipated 4-star Geo Polearm character hailing from the mysterious region of Nod-Krai. As a dedicated member of the Lightkeepers - specifically a Ratnik and squad leader - he embodies unwavering resolve in the face of the Wild Hunt's nightmares. His kit positions him as a versatile Geo support, excelling at amplifying Geo damage through Elemental Mastery scaling, Critical buffs, and synergies with Geo constructs and the new Lunar-Crystallize reaction (a lunar variant of Crystallize involving Geo and Hydro).

Expected to debut in Version 6.3 Phase 2 (around February 3-24, 2026) alongside Zibai's banner, Illuga's design rewards EM stacking on him while enabling explosive Geo damage for carries like Navia, Albedo, or Noelle. His bird companion, Gale (or A'Dong/Aedon), adds thematic flair to his attacks.

Normal Attack: Oathkeeper's Spear / Oath-Taking Spear Technique

Illuga performs up to four (or five, per some leaks) consecutive spear strikes, dealing Physical damage that converts to Geo in his kit context.

  • Charged Attack: Consumes stamina to lunge forward, dealing AoE Geo damage along the path.
  • Plunging Attack: Dives from mid-air, damaging enemies on descent and AoE upon impact.

Standard for Polearm users, but his personal damage is secondary to support utility.

Elemental Skill: Dawnbearing Songbird / Dawn-Breaking Messenger

Cooldown: 15 seconds.

Summons his loyal messenger bird, Gale, to dash at foes:

  • Tap: Gale lunges forward, striking enemies in its path for Geo damage.
  • Hold: Aim mode allows precise targeting; Gale charges the marked enemy for Geo damage on impact.

Gale, born in coexistence with the Moonforce, serves as a steadfast sentinel against the Wild Hunt. This skill triggers his key passive for team buffs and provides minor off-field damage.

Elemental Burst: Shadowless Reflection / Light Unshaded

Energy Cost: 60 | Cooldown: 15 seconds | Duration: 20 seconds.

Illuga lights his lantern, dealing AoE Geo damage and activating Haunted Night's Oriole-Song / Nightingale's Nocturne. He gains 21 stacks of Nightingale's Song:

  • Party members' Geo damage (from Normal/Charged/Plunging Attacks, Skills, or Bursts) consumes 1 stack per hit (multi-hit enemies consume more).
  • Each Geo hit gains a damage bonus scaling with Illuga's Elemental Mastery (exact % TBD in final talents).
  • Lunar-Crystallize Bonus: Further amplifies the increase.
  • Geo Construct Synergy: +5 stacks per on-field Geo construct (e.g., Zhongli's dome, Geo Traveler constructs) from party members, max +15 stacks.

Effect ends when stacks deplete or 20 seconds pass. This is Illuga's core: a stack-based Geo amp that shines in construct-heavy teams and rewards frequent Geo application.

Teams:

  • Lunar Geo: Zibai, Columbina, Gorou/Illuga (C2+).
  • Mono Geo: Navia, Zhongli, Furina/Jean.
  • Crystallize: Albedo, Furina, Zhongli.

Illuga revitalizes Geo supports, bridging classic resonance with lunar mechanics. A must-pull for Geo mains - his lantern promises to light up the Abyss.
