Xilonen, the Nanatzcayan Smith of Natlan

Rarity	(5-Star)
Element	Geo
Weapon	Sword
Best Role	Universal Support / Healer
Stat Priority	DEF > ER > CRIT Rate (Fav)
Tier	SS (Kazuha Rival)

Xilonen is the legendary Smith of the Nanatzcayan. She fundamentally changes the meta by offering Universal RES Shred (Geo + PECH elements) and potent healing in a single slot. She is essentially "Geo Kazuha" but with built-in sustain, making her one of the most valuable pulls in Natlan.

Pros

Shreds RES for Pyro/Hydro/Cryo/Electro AND Geo simultaneously.
Strong single-target healing (scales on DEF).
Best user of the "Scroll of Cinder City" support set.
Excellent overworld mobility (Wall skating).
Very F2P friendly (Craftable DEF sword is great).

Cons

Does not group enemies (unlike Kazuha).
Healing is single-target only (active character).
Requires specific team elements (PECH) to activate shred.
Cannot shred Anemo or Dendro RES.

Quick Guide (TL;DR)

If you don't have time for the math, here is the cheat sheet.

Best Artifact: 4pc Scroll of the Hero of Cinder City (Support BiS).
Alt Artifact: 4pc Husk of Opulent Dreams (Personal DMG / C6).
Best Weapon: Peak Patrol Song (Signature).
Alt Weapon: Freedom-Sworn (Team Buffs).
F2P Weapon: Flute of Ezpitzal (Craftable DEF Sword) or Favonius Sword.
Main Stats: SANDS: DEF% or ER | GOBLET: DEF% | CIRCLET: Healing Bonus or CRIT Rate.
Talent Priority: Elemental Skill > Elemental Burst > Normal Attack.
Top Team: Xilonen + Neuvillette + Furina + Kazuha (Hypercarry).

Pro Tip: N2 Activation: After casting her Skill (E) to enter Nightsoul state, you must perform 2 Normal Attacks. This maxes her Nightsoul points and activates her Source Samples, triggering the RES Shred. Do not swap out immediately!

Talent Breakdown & Mechanics

Elemental Skill: Yohual's Scratch

Blade Roller: Xilonen enters the "Nightsoul's Blessing" state (Roller Skates).
Source Samples: She has 3 "Samplers". By default, they are Geo. They change color based on teammates:
- Pyro/Hydro/Cryo/Electro: Converts a Sampler to that element.
- Activation: While skating, perform 2 Normal Attacks to max out Nightsoul points and activate the Samplers.
- Effect: Once activated, she shreds 36% RES for all active Sample elements (and Geo) for 15s. This works off-field.

Elemental Burst: Ocelot's Cue!

Cost: 60 Energy | Cooldown: 15s
Stereo Mix: Deals AoE Geo DMG based on DEF.
Effect Logic:
- 2+ PECH Teammates: The burst becomes a rhythmic Healer, restoring HP to the active character based on Xilonen's DEF.
- 2+ Geo Teammates: The burst deals two additional instances of massive Geo DMG (Sub-DPS mode).

Passive: Netotiliztli's Echoes

Nightsoul Burst: When a party member triggers a Nightsoul Burst (Natlan mechanic), Xilonen gains DEF%.
The Shred: The actual RES Shred comes from her Skill (Sample Activation), but this passive reinforces her DEF scaling.

Talent Priority Order:

Elemental Skill (Level 10) - Improves RES Shred percentage.
Elemental Burst (Level 9) - Improves Healing/Damage.
Normal Attack (Level 1) - Ignore unless C6.

Stat Requirements & ER Thresholds

Xilonen needs DEF for everything. ER is needed if you rely on her healing.

Role	Stat Goal (DEF)	ER Requirement
Support / Healer	3,200+	180% - 200%
Support (Favonius)	2,800+	160% - 180%
Geo Mono DPS	Max DEF/Crit	120% - 140%

Substat Priority:

DEF% (Primary scaling)
Energy Recharge (Vital for healing)
CRIT Rate (Only if using Favonius Sword)
Flat DEF

Best Artifacts Comparison

Set Name	Role	Reasoning
4pc Scroll of the Hero of Cinder City	BiS Support	After triggering a reaction, restores energy. If she triggers a reaction in Nightsoul state (E), she grants 40% Elemental DMG Bonus to the team for 20s. Unbeatable.
4pc Husk of Opulent Dreams	Personal DMG	Use this only if you play her in Mono Geo DPS teams (e.g. with Itto) and someone else holds Scroll.
4pc Maiden Beloved	Pure Heal	Overkill on healing, but valid if you are struggling to survive Furina's drain without her signature weapon.

Weapon Rankings

Weapon	Type	Performance	Notes
Peak Patrol Song	DEF%	S+	Signature. Massive DEF stats and buffs party Elemental DMG based on DEF. Hard to beat for buffing potential.
Favonius Sword	ER%	S	The premier F2P/Support option. Solves her energy needs and batteries the team. Requires Crit Rate on artifacts.
Flute of Ezpitzal	DEF%	A (F2P)	Natlan Craftable. High DEF stat stick. Good for maximizing healing if you don't need the Favonius particles.
Freedom-Sworn	EM	A (Buffs)	Buffs NA/CA damage for teammates. Good for Arlecchino/Neuvillette teams, but EM main stat is useless for Xilonen herself.

Constellation Value

Xilonen's C2 makes her arguably the strongest support in the game.

C1: "Ocelot's Relaxation" - (QoL) Increases resistance to interruption while skating. Reduces Nightsoul consumption. Makes her feel much smoother to play.
C2: "Pentstatic Fruit-Picking" - (Broken) The Geo Source Samples always remain active. Additionally, active samples grant massive team buffs based on element:
• Geo: +50% DMG Bonus.
• Pyro: +45% ATK.
• Hydro: +45% HP.
• Cryo: +60% CRIT DMG.
• Electro: +25 Energy Refund.
C6: "Perpetual Carnival" - (DPS) Ignores Nightsoul limitations and grants massive damage scaling based on DEF. Turns her into a Main DPS for 5s.

Verdict: C0 is S-Tier. C2 is arguably the best constellation in the game.

Top Team Compositions

1. Neuvillette Hyper

Main DPS: Neuvillette
Support: Xilonen (Hydro Sample)
Buffer: Furina
Anemo: Kazuha

Why it works: Xilonen shreds Hydro RES (Stacking with Kazuha's VV). Her healing stacks Furina's Fanfare. If C2, she gives Neuvillette +45% HP, which is a massive damage increase. She replaces Baizhu/Zhongli here.

2. Arlecchino Vaporize

Main DPS: Arlecchino
Hydro: Yelan
Support: Xilonen (Pyro/Hydro Samples)
Buffer: Bennett

Why it works: Xilonen shreds both Pyro and Hydro RES simultaneously (Double Swirl equivalent). She provides healing comfort for the team (though Arle can't be healed, teammates can) and the Scroll set buff.

Rotations & Combos

Standard Support Rotation:
Xilonen E (Enter Skate) > N2 (2 Normal Attacks to activate Samples) > Xilonen Q (Heal) > Swap to DPS

Tip: You MUST do the 2 Normal Attacks after casting E. If you swap immediately, the RES shred will not activate. Watch for the sampling meter to fill up.

Frequently Asked Questions

Is she better than Kazuha?
She is a side-grade with different utility. Kazuha groups enemies better and buffs DMG%. Xilonen heals and buffs/shreds without needing to Swirl (easier to use). They can be used together for massive damage.

Does she work in Mono Geo?
Yes, but she loses her PECH versatility. In Mono Geo (Itto), she acts as a healer and Geo buffer/shredder, replacing Zhongli or Albedo depending on the need for shields vs healing.
