Geo
Polearm
Illuga
Nightmare's Burning Heart
A lantern-bearing Moonsign warrior from Nod-Krai, Illuga is a Geo support who scales on Elemental Mastery. His Burst gives him a pool of Nightingale's Song stacks that add damage to the active character's Geo hits, with a much bigger bonus on direct Lunar-Crystallize DMG. He is one of the best amplifiers for Zibai's Lunar-Crystallize team, even at C0.

Main stats
Substat priority
Stat targets
- Energy Recharge 140–160% with Favonius Lance, 160–180% otherwise (about 30% less from C1)
- Then as much Elemental Mastery as possible (750+ is a good goal)
- CRIT Rate only for Favonius Lance procs
Talent priority
His Burst scales his Nightingale's Song bonus, so it is the only talent worth leveling. Leveling him to 80/90 is worthwhile for the EM from ascension.
Recommended teams
Zibai Lunar-Crystallize
His best team and the premium Lunar-Crystallize lineup: Moondrifts give him extra stacks and every Zibai hit gets his EM-based bonus.
Zibai with Gorou
Without Linnea, Gorou adds DEF and Geo DMG buffs; Columbina remains the key Hydro and Lunar support.
How to play
How he works
- Shadowless Reflection (Burst, 60 Energy) deals AoE Geo DMG and grants Haunted Night's Oriole-Song for 20s with 21 stacks of Nightingale's Song. Each Geo hit from the active character consumes a stack to add DMG based on Illuga's EM, much more if it is Lunar-Crystallize DMG. Every Geo Construct on the field (Moondrifts count) adds 5 stacks, up to +15.
- Demonhunter's Dusk raises that bonus with the number of Hydro and Geo characters in the party (1/2/3, Illuga included): it is maxed automatically in Lunar-Crystallize teams.
- Dawnbearing Songbird (Skill) sends his bird Aedon for Geo DMG and 4–5 Energy particles. The tap version is faster and almost always better.
- Torchforger's Covenant: after his Skill or Burst, teammates gain +5% CRIT Rate and +10% CRIT DMG for Geo DMG for 20s, plus +50 EM at Moonsign: Ascendant Gleam.
- Moonsign Benediction: Unwithering in Winter: he raises the party's Moonsign by one level.
Rotation
- E then Q before your carry (or Q then E to funnel his particles to an Energy-hungry teammate).
- Swap to your Geo or Lunar-Crystallize DPS and hit as much as possible while the stacks last.
His Normal Attacks are only worth using to trigger Favonius Lance or a teammate's on-hit effects.
Strengths
- Very strong buffs for Lunar-Crystallize carries, one of the best archetypes of 7.1
- Decent CRIT and EM buffs for any Geo damage
- Complete at C0, and his constellations are easy to get as a 4-star
- Great Energy generation from his Skill
Weaknesses
- Very inflexible: he only truly shines in one team
- His main buff (Nightingale's Song) only applies to the active character's Geo hits
- Stiff competition at C0 from a C6 Gorou
Notable dupes · Constellation
12 Energy after a Geo reaction on the field: cuts his ER needs by about 30%, so he can build more EM.
Aedon strikes every 7 stacks consumed: low damage, but it triggers Lunar-Crystallize and keeps Silken Moon's Serenade active.
+200 DEF for the active character during his Burst, useful for DEF-scaling carries like Zibai.
His passive rises to +10% CRIT Rate, +30% CRIT DMG and +80 EM: the biggest gain (about +20% team damage overall).
