Illuga Kit Overview

Here is a table that shows how Illuga’s polearm fits in teams:

Character	Role in Team Composition
Columbina	Makes Lunar-Crystalize reaction for Illuga
Zibai	Makes Lunar-Crystalize reaction for Illuga
Hydro	Helps Illuga do more damage with synergy
Geo	Helps Illuga do more damage with synergy

You should learn how the Illuga Kit works. It helps you make teams that use Geo reactions and shields. This helps you get ready for version 6.3. You can use Illuga’s skills better in fights.

Role and Playstyle

Illuga is a support who boosts Geo damage. His playstyle is different from other Geo supports. You get EM-scaling buffs for more Geo damage. You earn Nightingale’s Song stacks by making Geo constructs. These stacks give your team extra buffs.

• Illuga’s skills turn EM-scaling buffs into Geo damage.
• You help your team by making Geo constructs and reactions, like Lunar Crystallization.
• The Illuga Kit is best for players who like reaction Geo teams.

You use his Elemental Burst to make a special damage time. All Geo hits during this time use EM, so you want Hydro or Geo in your team for more synergy. His constellation set boosts EM and CRIT stats. This makes your team stronger in fights with reactions. For more on 6.3 character roles, see our 6.3 Update Guide.

You should learn the Illuga Kit if you want to build teams with Geo constructs and get more buffs. This helps you use Illuga’s skills well in version 6.3.

Illuga Kit Skills

Oathkeeper’s Spear (Normal Attack)

You use Oathkeeper’s Spear as Illuga’s normal attack. This attack lets you strike up to five times in a row. Each hit deals Geo damage. When you hold the attack button, Illuga performs a charged thrust. This move uses stamina and deals extra damage. If you jump or dash, you can trigger a plunging attack. This attack hits enemies on the ground and creates a small Geo shockwave.

Tip: Use normal attacks to build up Nightingale’s Song stacks. These stacks help you boost your team’s Geo damage later.

You should use Oathkeeper’s Spear to keep pressure on enemies. The attack chain feels smooth and works well with the rest of the Illuga Kit.

Dawnbearing Songbird (Elemental Skill)

Dawnbearing Songbird is Illuga’s Elemental Skill. When you press the skill button, Illuga summons a Geo construct shaped like a songbird. This construct creates a shield for your active character. The shield absorbs damage and scales with Illuga’s max HP. If you hold the skill button, the shield becomes stronger and lasts longer.

The Geo construct also deals AoE Geo damage when it appears. Enemies near the construct take extra damage. You can use this skill to protect your team and trigger Geo reactions.

• Press to summon a basic shield and deal damage.
• Hold to create a stronger shield and boost the shield’s duration.
• Use the shield to block attacks and keep your team safe.

You should use Dawnbearing Songbird to protect your main damage dealer. The shield lets you play more aggressively. The skill also helps you trigger the Lunar-Crystalize reaction with Hydro or other Geo characters.

Shadowless Reflection (Elemental Burst)

Shadowless Reflection is Illuga’s Elemental Burst. When you activate this burst, Illuga creates a large Geo field. All allies inside the field gain a boost to their Elemental Mastery (EM). This boost increases the damage of Geo reactions. The burst also deals a big hit of AoE Geo damage when it starts.

During the burst, every Geo construct you create gives your team more buffs. You can stack these buffs for even higher damage. The burst lasts for several seconds, so you have time to use other skills and attacks.

Note: Use Shadowless Reflection when you want to boost your team’s Geo reaction damage. Try to have as many Geo constructs on the field as possible.

You should time this burst for big fights or boss battles. The burst works best when you combine it with other Geo or Hydro characters.

Passive Talents

Illuga’s passive talents give you extra benefits when you use his skills. The first passive increases the shield strength from Dawnbearing Songbird. Your team takes less damage when the shield is active. The second passive gives you more Nightingale’s Song stacks when you create Geo constructs. This helps you reach higher buffs faster.

The third passive talent boosts your team’s EM when you trigger the Lunar-Crystalize reaction. This bonus lasts for a few seconds and helps you deal more damage with Geo reactions.

Here is a table that shows Illuga’s passive talents and their effects:

Passive Talent Name	Effect
Songbird’s Protection	Increases shield strength from Dawnbearing Songbird
Nightingale’s Gift	Grants extra stacks when creating Geo constructs
Dawn’s Harmony	Boosts EM after triggering Lunar-Crystalize

You should pay attention to these passive talents. They make the Illuga Kit stronger and help you support your team better.

Illuga Skill Mechanics

Nightingale’s Song Stacks

Nightingale’s Song stacks are very important for Illuga. When you use Illuga’s Elemental Burst, you get 21 stacks right away. Every time you or your teammates do Geo damage, you use up one stack. These stacks make your attacks stronger if Illuga has high Elemental Mastery. If you hit more than one enemy at the same time, you can use more than one stack in one attack. When you make the Lunar-Crystallize reaction, your damage boost gets even bigger.

• Illuga’s Burst gives you a short time for more Geo damage.
• You start with 21 Nightingale’s Song stacks when you use Burst.
• Each Geo attack uses one stack and gets stronger with Elemental Mastery.
• Lunar-Crystallize reactions make your boost even higher.
• Hitting lots of enemies at once can use up stacks faster.

Tip: Use your best Geo attacks while Burst is active to get the most from your stacks.

EM-Scaling Buffs

Illuga’s Elemental Mastery buffs make him different from other supports. The Illuga Kit lets you give your team a big Elemental Mastery boost. This helps your team do more damage with Geo reactions. You can see how Illuga compares to other support characters in the table below:

Character	EM Buff (%)	Additional Effects
Illuga	+200%	Works with Hydro, Geo, and Lunar, up to 21 stacks
Columbina	Higher DPS	Good at Hyperbloom reactions

You get the best results from Illuga’s EM buffs when you use Hydro or other Geo characters with him. This makes your reactions stronger and helps you win tough battles faster.

Practical Combat Uses

You can use the Illuga Kit to help your team defend and attack. Illuga’s shields keep your team safe from damage. His energy generation lets you use bursts more often. In Spiral Abyss, Illuga is a strong Geo support. You get 15-25% more damage for Zibai than with other supports. The Illuga Kit also gives you a 95% chance to finish your team’s rotation and a 98% chance to have Burst ready at the start.

• Strong shields keep your main attacker safe.
• Fast energy generation helps your team use big attacks often.
• High burst uptime means you almost always have buffs.

Note: Illuga’s skills work best if you plan your attacks around his Burst and how you use stacks.

Illuga Constellations

Constellation 1: Songbird’s Oath

When you get Illuga’s first constellation, you unlock Songbird’s Oath. This lets Dawnbearing Songbird make a second Geo construct. You get stronger shields and more chances for Geo reactions. Your team is safer in hard fights. The extra construct helps block attacks and control the area.

Tip: Put both constructs close to enemies. This gives you better shield coverage and more reaction chances.

Constellation 2: Dawn’s Blessing

Dawn’s Blessing makes your shield stronger. If you hold Dawnbearing Songbird, the shield takes more hits. When the shield breaks, you get a short heal. Your team can live longer against tough bosses. Illuga gives extra safety when enemies do lots of damage.

Constellation 3: Songbird Ascendant

Songbird Ascendant raises Illuga’s Elemental Burst level by 3. This makes Shadowless Reflection last longer and hit harder. Your team gets better Elemental Mastery buffs and more Geo damage. The table below shows what this does:

Aspect	Effect
Constellation 3	Increases the Level of her Elemental Burst by 3

Pick this constellation if you want bigger burst damage and longer buffs.

Constellation 4: Shadow’s Embrace

Shadow’s Embrace gives your team more CRIT Rate inside Illuga’s Geo field. You can hit enemies for more damage and win fights faster. Your Geo reactions work better. Your main attacker gets more critical hits.

Constellation 5: Oathkeeper’s Vow

Oathkeeper’s Vow boosts Dawnbearing Songbird’s level by 3. This makes your shield stronger and gives more AoE damage. Your team gets better defense and more skill damage. This constellation helps Illuga’s shields last longer in boss fights.

Constellation 6: Nightingale’s Finale

Nightingale’s Finale gives Illuga his best support power. When you use Shadowless Reflection, your team gets extra Geo damage for each Nightingale’s Song stack used. You can beat groups of enemies fast. Your team gets stronger shields and better reaction damage.

Note: Nightingale’s Finale makes Illuga great for Geo reaction teams. Use this constellation for the most support and damage.

Optimizing Illuga

Best Teams

Illuga works well as a Geo support. He helps teams that use Geo reactions and shields. Here are three strong team setups for Illuga:

Zibai, Illuga, Xilonen (C2), Gorou, Columbina

This team has good Geo synergy and strong shields.

Zibai, Illuga, Kokomi, Chiori, Albedo

Kokomi heals and helps with Hydro reactions.

Navia, Illuga, Furina, Columbina

You get more Geo damage and fast reactions.

Tip: Use Illuga with Hydro or Geo characters. This helps you trigger Lunar-Crystallize and use his EM buffs better.

Weapons and Artifacts

Pick weapons for Illuga that boost HP or Energy Recharge. These stats help you keep shields up and use Burst more often. The best polearms for Illuga are:

• Favonius Lance: Gives more energy for bursts.
• Black Tassel: Raises HP for stronger shields.

For artifacts, choose sets that make shields better and raise Elemental Mastery. Good sets are:

Artifact Set	Main Benefit
Tenacity of the Millelith	Makes shields and team attack stronger
Emblem of Severed Fate	Boosts energy recharge

Pick HP% or EM for sands, goblet, and circlet main stats. For more building tips, check out our guide on best F2P weapons.

Constellation Priorities

Unlock Illuga’s first constellation, Songbird’s Oath, early. It gives you another Geo construct and better shields. Constellations 3 and 6 make burst damage and team support much stronger. If you want better defense, get Constellation 2 for shield upgrades.

Note: Early constellations help protect your team. Later ones give more damage and reaction power.
