Illuga will be released as part of the Version 6.3 Luna IV's Phase 2 update on February 3, 2026!
Version 6.3 - Release Date and Details
Illuga is a support that is designed to buff Lunar-Crystallize DMG through his Elemental Burst. His buffing capabilities primarily scale with Elemental Mastery, making him straightforward with what he wants in his builds.
Prioritize stacking Elementary Mastery to increase his potency as a buffer, and build him with Silken Moon’s Serenade to enhance his supportive capabilities even further.

| Sample Teams | |
For the most part, Illuga wants to have Elemental Mastery as much as possible to maximize his buffing capabilities.
Afterwards, focus on providing him the required Energy Recharge that will let him use his Elemental Burst off cooldown, as his DMG% buff is tied to it.
As a Moonsign support, it's natural that he'll gravitate towards Silken Moon's Serenade as his best-in-slot, alleviating his Energy Recharge needs while also enhancing Lunar-Reaction DMG to the team.
A pair of 2-pc Elemental Mastery set is a viable option for his buff’s scaling with Elemental Mastery. In a similar note, the Instructor set is an F2P option that increases the entire team’s Elemental Mastery.

Effects from Gleaming Moon cannot stack. |

List of Artifacts and Set Bonuses
Favonius Lance is generally his best-in-slot to alleviate, not just his Energy needs, but the entire team’s, and it's easily accessible.
A good alternative is Dragon’s Bane for its Elemental Mastery stat, but the effect is redundant for the most part. Kitain Cross Spear for a similar reason and can give Energy for Illuga, albeit delayed.

Favonius Lance
|
Base ATK: 565 Bonus Stat: Energy Recharge 30.6% Skill Effect: CRIT Hits have a 60% chance to generate a small amount of Elemental Particles, which will regenerate 6 Energy for the character. Can only occur once every 12s. |

Kitain Cross Spear
|
Base ATK: 565 Bonus Stat: Elemental Mastery 110 Skill Effect: Increases Elemental Skill DMG by 6%. After Elemental Skill hits an opponent, the character loses 3 Energy but regenerates 3 Energy every 2s for the next 6s. This effect can occur once every 10s. Can be triggered even when the character is not on the field. |
Illuga finds his best use to be with teams dedicated to Lunar-Crystallize to take advantage of his entire kit. It’s important to note that Illuga cannot trigger Lunar-Crystallize alone; he must be paired with a Moonsign character that has the ability to do so, particularly Zibai and Columbina.
| Character | Explanation |
|---|---|
|
|
Main DPS Illuga is the best support for Zibai, whose entire kit revolves around Lunar-Crystallize. She easily stacks Nightingale's Song because of her Elemental Skill and Normal Attacks, which in turn increase her overall damage. |
|
|
Support Columbina allows the team to trigger Lunar-Crystallize, and Illuga fits right in to buff the said reaction. They both buff the same reaction and make a great duo for teams dedicated to Lunar-Crystallize. |
|
|
Support As a fellow Geo character, Illuga helps Gorou activate his General's War Banner buffs. These buffs can increase the team's DEF and Geo DMG. With C4, Gorou can also act as a healer, albeit less reliably. |

Zibai is especially appreciative of Illuga's buffing capabilities for Lunar-Crystallize, making them a tandem when it comes to Zibai's teams.
Illuga contributes a lot to Zibai’s damage, but he is not a hard requirement for the latter to function.

Illuga can still fight right into general Lunar-Crystallize, but he must be paired with Columbina to make use of his entire kit, Lunar reactions, and Ascendant Gleam.
Take note that the output of this team is significantly less without a dedicated Lunar-Crystallize DPS.
Illuga functions as a Lunar-Crystallize and Geo Buffer, providing Element and Reaction-specific buffs via his Elemental Burst and passives.
In this case, he can serve as both a general Geo damage buffer, or a Lunar team damage buffer, with his kit catered towards general Geo DMG, but unlocking more if slotted into Lunar teams.
Lunar-Crystallize Reaction Guide
Illuga's Elemental Burst illuminates the area around the active character, increasing the Geo and Lunar-Crystallize DMG dealt by this character based on Illuga's Elemental Mastery.
This is Illuga's main way of providing support to his team.
Apart from his Elemental Burst, Illuga's Lightkeeper's Oath passive lets him buff the party's Geo CRIT Rate and CRIT DMG, and even increases the team's Elemental Mastery if Ascendant Gleam is activated.
As a senior member of the Lightkeepers, one of Illuga's Lore-related passives allow him to understand the otherwise incomprehensible chatter of Wild Hunt opponents.

Members of the Lightkeepers are under no obligation to stay — and many do, in fact, leave shortly after joining. Only the most determined persevere, and Illuga is one such example. It is common to admire those who display wit and cunning, but to me, determination is a far more valuable quality. |
