Elemental resistance support, healer, and Geo damage dealer
Released Oct 9, 2024
Xilonen is a Sword user whose Skill activates Source Samples that reduce nearby opponents' resistance to selected elements, with the active samples determined by party composition. Her Burst heals when at least two samples have changed from Geo to other elements; otherwise it adds Geo damage. Consider her when the matching elements and her support effects suit the encounter.

Xilonen GUIDE
Understand Xilonen
Useful when…
Reducing nearby opponents' resistance to party-represented Pyro, Hydro, Cryo, or Electro elements.
Healing nearby active characters with her Burst when at least two Source Samples change element.
Using Nightsoul's Blessing for faster movement and climbing, especially in Natlan.
Skill, samples, and resistance reduction
Yohual's Scratch deals Nightsoul-aligned Geo damage based on DEF, grants 45 Nightsoul points, and puts Xilonen in Blade Roller mode. She carries three Source Samples, initially Geo; each Pyro, Hydro, Cryo, or Electro party member changes one Geo Sample to that element. A Geo Sample always remains active while Xilonen is in Nightsoul's Blessing. When her points reach their maximum, they are spent to activate all three samples for 15 seconds; nearby opponents' corresponding elemental resistance is reduced by 9% at the listed level-one value. The same-element Source Sample effects do not stack, and Xilonen can trigger the effects while off field. Her Nightsoul state consumes points and ends when they are depleted or the Skill is used again; points have a nine-second limit.
Movement, Burst, and party conditions
In Blade Roller mode, Normal Attacks become up to four kicks that deal DEF-based, Nightsoul-aligned Geo damage; Charged Attacks are unavailable. The mode increases movement speed and climbing speed, and permits high-speed leaps while climbing. Ocelotlicue Point! deals AoE Geo damage based on DEF. Its branch depends on the party: at least two changed Source Samples create an Ebullient rhythm that heals nearby active characters at intervals based on DEF; fewer than two changed samples instead create an Ardent rhythm with two additional Geo damage beats. This makes party-element composition determine whether the Burst heals or adds damage, so check the Source Samples before using it for a specific purpose.
Nightsoul upkeep and investment
With at least two changed samples, Netotiliztli's Echoes restores 35 Nightsoul points when Xilonen's Normal or Plunging Attacks hit during her Nightsoul state, once every 0.1 seconds. With fewer than two changed samples, those attacks instead deal 30% increased damage. Points expire after the state’s time limit; after they expire, this passive can no longer regenerate them during that state. The Skill track improves the support-defining Skill and sample effect, while the Burst track matters for its healing or damage branch. Normal Attack investment is conditional on her personal attack use. Her ascension needs Prithiva Topaz, Brilliant Chrysanthemum, whistles, and Gold-Inscribed Secret Source Core at later stages.
Limits and common mistakes
The Burst does not always heal: fewer than two changed samples selects the two additional damage beats. Resistance reduction applies to the elements represented by active samples, and repeated samples of one element do not stack their effects. Blade Roller mode removes access to Charged Attacks. Nightsoul points are time-limited, so do not assume that staying in the state indefinitely will continue generating points, particularly after they have expired.
Limitations and tradeoffs
Party composition determines which resistance reductions are available and whether the Burst heals or deals extra damage.
Staying in the Skill state has a point and time limit; its movement mode prevents Charged Attacks.
Her attack damage, sample support, and Burst healing rely on different mechanics and conditions.
Common mistakes to avoid
Assuming the Burst heals regardless of how many Source Samples changed element.
Expecting repeated Source Samples of one element to stack resistance reduction.
Using Charged Attacks during Blade Roller mode, where they are unavailable.

Yohual's Scratch · Elemental skill
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 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 Sample 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 Ascension Talent, "Netotiliztli's Echoes," Xilonen can trigger said Ascension 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 Ascension Talent "Netotiliztli's Echoes."

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: 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.
