Illuga — Build, Teams & Rating Genshin 6.7

Is Illuga worth building?

Illuga doesn't do much damage himself, but he's the key that pushes Zibai and the whole Lunar-Crystallize team well above their normal ceiling — his EM buff scales directly with reaction damage. Favonius Lance or the craftable Kitain Cross Spear are plenty, no premium weapon needed. Prioritize Energy Recharge first so he can burst every rotation, then stack as much Elemental Mastery as possible through the Silken Moon's Serenade set. If you're not building a Crystallize team, Illuga is close to useless — don't waste resources on him.

Illuga's talents

Oathkeeper's Spear

Normal Attack
Performs up to 4 consecutive spear strikes.

Charged Attack
Consumes a certain amount of Stamina to lunge forward, dealing damage to opponents along the way.

Plunging Attack
Plunges from mid-air to strike the ground below, damaging opponents along the path and dealing AoE DMG upon impact.

Dawnbearing Songbird

Summons the trusty messenger bird, "Aedon." Different effects are produced depending on whether the skill is Tapped or Held.

Tap
Aedon dashes towards enemies in front, dealing Geo DMG to enemies it comes into contact with.

Hold
Enter aiming mode, and command Aedon to dash towards opponents being aimed at, dealing Geo DMG to opponents it comes into contact with.

Shadowless Reflection

Light the lamp, dealing AoE Geo DMG, and gain Haunted Night's Oriole-Song effect for 20s. When this effect is active, Illuga gains 21 stacks of Nightingale's Song. When Normal Attacks, Charged Attacks, Plunging Attacks, Elemental Skills, and Elemental Bursts of nearby active party members deal Geo DMG to opponents, 1 stack of Nightingale's Song is consumed to increase the DMG dealt. Increase in DMG is based on Illuga's Elemental Mastery. If DMG is inflicted by Lunar-Crystallize, DMG dealt will increase further.
When Geo DMG dealt in this manner hits multiple opponents, multiple stacks of Nightingale's Song will be consumed, depending on how many opponents are hit.

Additionally, if there are Geo Constructs created by nearby party members on the battlefield while Illuga unleashes his Elemental Burst, or when nearby party members create Geo Constructs while Haunted Night's Oriole-Song is active, every Geo Construct on the battlefield will allow Illuga to gain 5 additional stacks of Nightingale's Song. Within 20s after unleashing his Elemental Burst, Illuga can gain a maximum of 15 additional stacks of Nightingale's Song this way.

When all stacks of Nightingale's Song have been consumed, or when the state's duration ends, the Haunted Night's Oriole-Song effect will end.

Torchforger's Covenant

After unleashing Elemental Skill Dawnbearing Songbird or Elemental Burst Shadowless Reflection, other nearby party members will gain the Lightkeeper's Oath effect for 20s: For Geo DMG dealt to opponents, CRIT Rate increases by 5% and CRIT DMG increases by 10%.

Moonsign: Ascendant Gleam
Party members affected by the Lightkeeper's Oath effect have their Elemental Mastery increased by 50.

Demonhunter's Dusk

Nightingale's Song's effects are enhanced: When there are 1/2/3 Hydro or Geo characters in the party, Nightingale's Song will further increase DMG. Increase in DMG is equal to 7%/14%/24% of Illuga's Elemental Mastery. If this aforementioned DMG is inflicted by a Lunar-Crystallize reaction, increase in DMG is equal to 48%/96%/160% of Illuga's Elemental Mastery.

Moonsign Benediction: Unwithering in Winter

When Illuga is in the party, the party's Moonsign will increase by 1 level.

Night Warden's Stride

At night (18:00 – 06:00), your party members gain the Swift Stride effect: Movement SPD increased by 10%.
Does not take effect in Domains, Trounce Domains, or Spiral Abyss. Swift Stride does not stack.
Additionally, Illuga appears to be able to decipher the whispers of the Wild Hunt...

Combat Rotation

Tap the Elemental Skill (E) so Aedon dashes in for an opening Geo hit and starts building Energy.
Swap to the main DPS and attack normally while Illuga's Energy climbs toward the 60 needed for his Burst.
Unleash the Elemental Burst (Q, costs 60 Energy) – Shadowless Reflection: AoE Geo DMG plus the 20s Haunted Night's Oriole-Song effect carrying 21 stacks of Nightingale's Song.
If Geo Constructs (shields, pillars, etc.) are already on the field when Q goes off, or get placed within that 20s window, Illuga gains up to 15 extra stacks (5 per construct).
Swap the main DPS in immediately to land Geo DMG (Normal/Charged/Plunge/Skill/Burst) and burn through the Nightingale's Song stacks one by one, each adding bonus damage scaled off Illuga's Elemental Mastery.
Make use of the 20s Lightkeeper's Oath team buff (triggered by E or Q): nearby allies' Geo DMG gets +5% CRIT Rate and +10% CRIT DMG.
Once E is off cooldown (15s), tap Aedon again to keep the Geo pressure up and top off Energy.
Loop it: keep Illuga off-field while the main DPS spends stacks, then bring him back for another Burst as soon as 60 Energy is ready and the old 21 stacks are spent or expired.
