Genshin Impact: Xilonen Quick Character Guide • DotGG

Xilonen is a support character who can provide multi-Elemental RES reduction. Depending on the party composition, she can also deal DMG while of the field.

When Xilonen uses her Elemental Skill, she enters the Nightsoul's Blessing state, which will decrease the corresponding Elemental RES of nearby opponents based on the Elemental Types of your party members. Additionally, while decreasing the Geo RES of nearby opponents, her Normal and Plunging Attacks deal increased DMG.

Her Elemental Burst deals AoE Geo DMG, and based on the party composition, will either continuously heal the active character or deal two additional instances of DMG.

This guide is based on the Community Character Builds by the Genshin Helper Team.

Skills Overview

Normal Attack: Ehecatl's Roar

Normal Attack
Performs up to 3 rapid strikes.

Charged Attack
Consumes a fixed amount of Stamina and performs a forward kick.

Plunging Attack
Plunges from mid-air to strike the ground below, damaging opponents along the path and dealing AoE DMG upon impact, both based on Xilonen's DEF.

Nightsoul's Blessing: Blade Roller
When in the Nightsoul's Blessing state, Xilonen will enter the Blade Roller mode. While in this mode, Xilonen's Normal Attacks will allow her to perform up to 4 kicks using her roller blades, and she will be unable to use Charged Attacks.
When she uses Normal and Plunging Attacks in this mode, they will switch to being based on her DEF, and she will deal Nightsoul-aligned Geo DMG that cannot be overridden.

Elemental Skill: Yohual's Scratch

Let the rhythms of passion resound throughout the land! Xilonen switches to high-speed combat blading gear and rushes forward a certain distance before dealing Nightsoul-aligned Geo DMG based on her DEF.
After using this, Xilonen will gain 45 Nightsoul points and enter the Nightsoul's Blessing state. In this state, she will shift to the Blade Roller mode.

Source Sample Activation Duration: 15s
Nightsoul Point Time Limit: 9s
Nightsoul Point Limit: 90
CD: 7s

Source Samples
Xilonen has 3 Samplers with her that can generate different Soundscapes based on her other party members' Elemental Types, decreasing nearby opponents' corresponding Elemental RES while active.
The initial recorded Source Sample within each Sampler will be Geo, and for each party member who is Pyro/Hydro/Cryo/Electro, 1 Geo Sampler will change to that corresponding Element.
While Xilonen is in the Nightsoul's Blessing state, the Geo Source Sample she carries will always be active. After unlocking her Passive Talent, "Netotiliztli's Echoes," Xilonen can trigger said Passive Talent's effects to regenerate Nightsoul points for herself. When her Nightsoul points hit the maximum, she will consume all her Nightsoul points and activate the 3 Source Samples she has on hand for 15s.

When the Source Samples are active, nearby opponents' corresponding Elemental RES will decrease. Source Sample effects of the same Elemental Type cannot stack. Xilonen can trigger these effects even when off-field.

Nightsoul's Blessing: Xilonen
Continuously consume Nightsoul points. When these points are depleted or if used again, this Nightsoul's Blessing state will end. This state has the following traits:
● Switches to the Blade Roller mode, increasing Xilonen's Movement SPD and climbing speed, and she can perform high-speed leaps in Ocelot Form while climbing.
● Xilonen's Nightsoul's Blessing has the following restrictions: When in this state, Xilonen's Nightsoul points have a 9s time limit. After this limit passes, her Nightsoul points will immediately expire.

After Xilonen's Nightsoul points have expired while she is in the Nightsoul's Blessing state, she will no longer be able to generate Nightsoul points via the Passive Talent "Netotiliztli's Echoes."

Elemental Burst: Ocelotlicue Point!

Activates the Phlogiston Stereo DJ Controller (Portable) at full power, dealing Nightsoul-aligned AoE Geo DMG based on Xilonen's DEF.

CD: 15s
Energy Cost: 60

Additionally, she will trigger the following effects based on her different Source Samples:
● If she has at least 2 Source Samples that have had their Elemental Types changed, Xilonen will play an Ebullient rhythm, healing nearby active characters at intervals based on her DEF.
● If she has fewer than 2 Source Samples that have had their Elemental Types changed, Xilonen will start up an Ardent rhythm, which will play two additional beats that deal Nightsoul-aligned AoE Geo DMG based on her DEF.

Ascension 1: Netotiliztli's Echoes

While in the Nightsoul's Blessing state:
● If Xilonen has at least 2 Source Samples that have had their Elemental Types changed, she gains 35 Nightsoul points when her Normal or Plunging Attacks hit opponents. Can be triggered once every 0.1s.
● If Xilonen has fewer than 2 Source Samples that have had their Elemental Types changed, her Normal and Plunging Attacks deal 30% increased DMG.

Ascension 4: Portable Armored Sheath

While in the Nightsoul's Blessing state, when Xilonen's Nightsoul points reach the maximum, she will trigger an effect equal to that of her Nightsoul Burst. This effect can be triggered once every 14s.
Additionally, when nearby party members trigger a Nightsoul Burst, Xilonen's DEF is increased by 20% for 15s.

Night Realm's Gift Passive: Blessing of Forge-Fire

After her Nightsoul points are fully depleted, Xilonen will switch to consuming Phlogiston to maintain her Nightsoul's Blessing.
While in an area with Phlogiston Mechanics within Natlan, she can use Nightsoul Transmission: Xilonen. When the active character is currently sprinting, climbing, in a movement mode caused by certain Talents, or at a certain height in the air, the following will trigger when switching to Xilonen: Xilonen will enter the Nightsoul's Blessing state and gain 20 Nightsoul points. In this situation, Xilonen's Nightsoul points have a 4s time limit, after which her Nightsoul points will immediately expire. After she uses Yohual's Scratch within this time limit, her Nightsoul point time limit will be extended by 9s. Nightsoul Transmission can be triggered once every 10s by your own team.

Additionally, while in Natlan, Xilonen will not consume Stamina when climbing while in the Nightsoul's Blessing state.

Passive Talent: Tour of Tepeilhuitl

Triggering Nightsoul Transmission restores 15 Phlogiston.

TLDR / Rotation

Despite having a lengthy description of each talent, all you need to know about Xilonen is her Skill and Burst.
When using Skill, Xilonen will have 3 Source Samples (can be seen in the image above). By default, the Source Samples will be Geo. But if you have an elemental character (Pyro/Hydro/Electro/Cryo), the color of the Source Sample will change to those elemental characters.

Once you use Skill to enter Nightsoul's Blessing state and gain 3 Source Samples, use 2 Normal Attacks to fully replenish Nightsoul points. Once it's full, Xilonen will consume all those points and activate the Source Samples, decreasing opponents' corresponding Elemental RES. This is what makes her so good, comparable with Kazuha.

Now for her Burst, it also depends on the colors of her Source Samples.
● If she has at least 2 Source Samples that have had their Elemental Types changed (from Swirable elements), Xilonen will play an Ebullient rhythm, healing nearby active characters at intervals based on her DEF. This is what most would go after since Xilonen is better in the elemental team than the Mono-Geo team, especially in Furina's team.
● If she has fewer than 2 Source Samples that have had their Elemental Types changed, Xilonen will start up an Ardent rhythm, which will play two additional beats that deal Nightsoul-aligned AoE Geo DMG based on her DEF.

In short, you want to use Skill > Normal Attack x2 > Burst (for healing if you want).

Talent Priorities

Skill > Burst

If you do not need Xilonen's healing, her Burst can be ignored because her main buffs are from her Skill and Artifacts (+Weapon if you have her signature sword).

Recommended Weapons

Peak Patrol Song (5⭐)*
Freedom-Sworn (5⭐)*
Favonius Sword (4⭐)
Flute of Ezpitzal (4⭐)*
Skyrider Sword (3⭐)

Weapon options below Favonius Sword do not really affect Xilonen's performance as a Support.

1) Peak Patrol Song (ATK: 542 • DEF: 82.7%)

Gain "Ode to Flowers" after Normal or Plunging Attacks hit an opponent: DEF increases by 8~16% and gain a 10~20% All Elemental DMG Bonus for 6s. Max 2 stacks. Can trigger once per 0.1s. When this effect reaches 2 stacks or the 2nd stack's duration is refreshed, increase all nearby party members' All Elemental DMG Bonus by 8~16% for every 1,000 DEF the equipping character has, up to a maximum of 25.6~51.2%, for 15s.
Note: The buff from this weapon caps out once Xilonen reaches 3,200 DEF.

2) Freedom-Sworn (ATK: 608 • Elemental Mastery: 198)

A part of the "Millennial Movement" that wanders amidst the winds.
Increases DMG by 10~20%.
When the character wielding this weapon triggers Elemental Reactions, they gain a Sigil of Rebellion. This effect can be triggered once every 0.5s and can be triggered even if said character is not on the field.
When you possess 2 Sigils of Rebellion, all of them will be consumed and all nearby party members will obtain "Millennial Movement: Song of Resistance" for 12s.
"Millennial Movement: Song of Resistance" increases Normal, Charged, and Plunging Attack DMG by 16~32% and increases ATK by 20~40%. Once this effect is triggered, you will not gain Sigils of Rebellion for 20s.
Of the many effects of the "Millennial Movement," buffs of the same type will not stack.
Note: This option is competitive with Peak Patrol Song if the team can utilize both of its buffs. To proc it consistently, you either need to burst every rotation, or add a delay between the initial skill hit and normal attacking. It is not needed to level this weapon for Xilonen.

3) Favonius Sword (ATK: 454 • Energy Recharge 61.3%)

CRIT hits have a 60~100% chance to generate a small amount of Elemental Particles, which will regenerate 6 Energy for the character. Can only occur once every 12~6s.

4) Flute of Ezpitzal (ATK: 454 • DEF: 69.0%)

Using an Elemental Skill increases DEF by 16~32% for 15s.
Note: Refinements for this weapon are insignificant on Xilonen.

5) Skyrider Sword (ATK: 354 • Energy Recharge 51.7%)

Using an Elemental Burst grants a 12~24% increase in ATK and Movement SPD for 15s.

Recommended Artifacts

Scroll of the Hero of Cinder City (4)*
Archaic Petra (4)
Noblesse Oblige (4)

If no other member of the team can hold it, Scroll of the Hero of Cinder City (4) should be the top priority for Xilonen. The other options are there in the event someone else has Scroll occupied. If you do not need Xilonen's healing ability and are not using Peak Patrol Song, her artifact stats do not matter.

1) Scroll of the Hero of Cinder City

2 Piece: When a nearby party member triggers a Nightsoul Burst, the equipping character regenerates 6 Elemental Energy.
4 Piece: After the equipping character triggers a reaction related to their Elemental Type, all nearby party members gain a 12% Elemental DMG Bonus for the Elemental Types involved in the elemental reaction for 15s. If the equipping character is in the Nightsoul's Blessing state when triggering this effect, all nearby party members gain an additional 28% Elemental DMG Bonus for the Elemental Types involved in the elemental reaction for 20s. The equipping character can trigger this effect while off-field, and the DMG bonus from Artifact Sets with the same name do not stack.

2) Archaic Petra

2 Piece: Geo DMG Bonus +15%
4 Piece: Upon obtaining an Elemental Shard created through a Crystallize Reaction, all party members gain 35% DMG Bonus for that particular element for 10s. Only one form of Elemental DMG Bonus can be gained in this manner at any one time.

3) Noblesse Oblige

2 Piece: Elemental Burst DMG +20%
4 Piece: Using an Elemental Burst increases all party members' ATK by 20% for 12s. This effect cannot stack.

Main & Sub Stats Priority

Artifact Main Stats	Artifact Sub Stats
Sands - DEF% / Energy Recharge Goblet - DEF% Circlet - DEF% / Healing Bonus / Crit Rate* *Crit Rate only if using Favonius Sword	Energy Recharge* DEF% Flat DEF Crit Rate** Prioritize ER until requirements are met *Crit Rate only if using Favonius Sword

Team Compositions

Choose a team composition with Pyro / Hydro / Electro / Cryo characters for Xilonen to get the buffs from her Skill.
For characters that utilize Anemo / Dendro / Physical, they don't have a good synergy with Xilonen, so it is not recommended to include these characters in the team. But there are certain characters that you can include in Xilonen's team like Kazuha and Nahida.
