Xilonen Build Guide - The Geo Groover Your Team Needs

Xilonen Overview

Xilonen is a 5-star Geo Sword user from Natlan who brings an incredible amount of utility to the table. As the first true Geo-based support with resistance shredding and healing capabilities, she reshapes team compositions for both Geo and non-Geo lineups. Her ability to provide off-field RES shred, single-target healing, and DEF-scaling buffs makes her a versatile pick for various content, especially in Spiral Abyss.

Rarity: ★★★★★
Element: Geo
Weapon: Sword
Role: Support / Healer
Region: Natlan
Voice (EN/JP): Beth Curry / Fairouz Ai

✅ Strengths:

  • Persistent RES Shred Aura: Her Skill applies Geo RES shred that persists across waves and doesn't require reactivation.

  • Low Investment Impact: Her support strength scales mainly with her Skill level and doesn’t require heavy investment to be effective.

  • Flexible Roles: Can act as both a healer and buffer; also has Sub-DPS potential.

  • Single-target Healing: Conditional healing through her Burst adds valuable sustain. (Team wide healing at c6)

  • Best Geo Buffer: Complements Geo teams and allows non-Geo DPS more flexibility.

❌ Weaknesses:

  • Elemental Restrictions: Needs two non-Geo units to fully activate her healing and shred aura.

  • Limited AoE Healing: Healing is single-target unless unlocked via C6.

  • Not Recommended for On-Field DPS at C0: Although it’s possible, it’s much less effective without constellations.

Should You Pull for Xilonen?

Xilonen is a versatile and powerful character to have on your team. Whether you're looking for a DEF-scaling DPS, a support who can shred Elemental RES, or even a sustainable healer with the right setup—Xilonen delivers it all with style. Her unique roller-blade combat and Nightsoul mechanics make her stand out in both performance and flair. If you're into characters that are fun to play, offer team utility, and have a unique kit, then yes—Xilonen is definitely worth pulling for!

🎯 Should You Pull for Her Constellations?

If you're already planning to invest in Xilonen, C2 is her biggest power spike — giving her permanent RES shred and teamwide buffs based on your composition. It significantly increases her value as both a support and buffer, making her fit into more team archetypes.

C1 and C4 are useful for comfort and additional utility, especially in quickswap or Normal Attack-heavy teams, but not essential.

✅ Verdict:

  • F2P/Light Spenders: C0 is very solid and already brings a lot of value.

  • Meta Optimizers: Aim for C2 if you want to fully unlock her support potential.

  • Whales/Enthusiasts: Consider going further if you enjoy her playstyle — especially C6 for an on-field carry conversion.

Recommended Build: Support/Healer Xilonen

Xilonen Best Weapons

Xilonen’s flexibility as a Geo Support allows her to shine with both DEF-scaling and Energy Recharge-focused swords. Whether you're investing in her supportive capabilities or planning a hybrid DPS approach, here are the top recommended weapons:

🥇 1. Peak Patrol Song (Best-in-Slot – DEF/Support Hybrid)

  • Base ATK: 542

  • Substat: DEF% (82.7%)

  • Effect:

    • Passive Buffs: Gain "Ode to Flowers" after hitting enemies with Normal or Plunging Attacks. Each stack increases DEF by 8% and grants 10% All Elemental DMG Bonus for 6s (up to 2 stacks).

    • Upon reaching or refreshing 2 stacks, nearby allies receive All Elemental DMG Bonus scaling with Xilonen's DEF—up to 25.6% for 15s.

  • Why It’s Great:
    Peak Patrol Song is tailor-made for Xilonen. It boosts her personal DEF while also granting a team-wide damage bonus based on her scaling stat. Ideal for both support and hybrid playstyles, this weapon brings out her full potential.

🥈 2. Freedom-Sworn (Support / Reaction Teams)

  • Base ATK: 608

  • Substat: Elemental Mastery (198)

  • Effect:

    • Increases DMG by 10%.

    • Grants a team-wide ATK and Normal/Charged Attack DMG buff after triggering Elemental Reactions and collecting Sigils of Rebellion.

  • Why It’s Great:
    Though not DEF-based, Freedom-Sworn shines in Elemental Reaction-heavy teams. It allows Xilonen to double as a reaction buffer, especially if you're pairing her with non-Geo units to trigger her RES shred.

🥉 3. Favonius Sword (F2P-Friendly / Energy Battery Option)

  • Base ATK: 454

  • Substat: Energy Recharge (61.3%)

  • Effect:

    • CRIT hits have a 60% chance to generate Energy particles (6 Energy, 12s cooldown).

  • Why It’s Great:
    This is the most accessible weapon for ensuring consistent Elemental Burst uptime. If you're early in the game or short on 5-star swords, Favonius Sword keeps her energy economy smooth, enabling her to heal and buff frequently.

Weapon Selection Tips:

  • Choose Peak Patrol Song for the best synergy with her DEF-scaling kit and party-wide buffs.

  • Opt for Freedom-Sworn if you're building around Elemental Reactions and want additional team utility.

  • Use Favonius Sword if you’re looking for easy Burst access and don’t have high Energy Recharge from artifacts.

Team Archetypes Featuring Xilonen

1. Universal Buffer Team (Any Elemental DPS + Furina + Kazuha + Xilonen)

  • Core Units: [Any Pyro/Hydro/Electro/Cryo DPS] + Furina + Kazuha + Xilonen

  • Strengths:

    • Xilonen acts as both the healer and RES shred buffer

    • Kazuha brings crowd control and additional Elemental DMG buffs

    • Furina synergizes well with Xilonen’s healing and buffs, amplifying team-wide damage

  • Why It Works:
    This composition is extremely flexible, letting you pick almost any Elemental Main DPS (such as Hu Tao, Neuvillette, or Ayaka). Xilonen enables smoother rotations and enhances overall damage with her persistent shred aura.

2. Vaporize Team (Xilonen + Xiangling + Mualani/Xingqiu/Yelan + Kazuha/Furina)

  • Core Units:Xiangling, Mualani/Yelan, Kazuha, Xilonen

  • Strengths:

    • Constant Pyro & Hydro RES shred

    • Minimal interference with Elemental Reactions

    • Additional Elemental DMG boosts from Kazuha and Xilonen

  • Why It Works:
    Xilonen’s low Geo application makes her perfect for reaction teams like Vaporize, where maintaining elemental interactions is crucial. Her healing adds extra sustainability for fragile characters like Xiangling.

3. Mono Element Team (Mono Pyro / Mono Cryo / Mono Hydro)

  • Core Units: Three same-element characters + Xilonen

  • Strengths:

    • Full benefit from Xilonen’s Elemental DMG buff and RES shred

    • Buffs stack across all characters using the same element

    Xilonen’s kit enables mono-elemental teams to shine by amplifying damage across the board. Whether you’re building Mono Pyro (with Bennett + Xiangling + Dehya) or Mono Hydro (with Furina + Neuvillette + Yelan), she scales the entire team's output.

4. Navia Premium Geo-Pyro Team (Navia + Bennett + Pyro Flex + Xilonen)

  • Core Units:Navia, Bennett, [Pyro Flex like Lyney or Xiangling], Xilonen

  • Strengths:

    • Activates Pyro Resonance for +25% ATK

    • Geo Resonance for increased shield strength and bonus DMG

    • Xilonen provides Geo RES shred, DEF-scaling support, and healing

  • Why It Works:
    Xilonen was practically made to work with Navia, enabling double resonance buffs while keeping Navia’s uptime strong. Her shred and buffs are especially effective in longer fights like Abyss bosses.

Final Tips for Team Building

  • ✅ Use Xilonen when you need both a buffer and a healer, freeing up a slot for an additional sub-DPS or reaction enabler.

  • ✅ Avoid placing her in full Geo teams unless you're using at least 2 non-Geo units—her RES shred requires Elemental diversity.

  • ✅ She excels in teams with Furina or Kazuha, both of whom greatly amplify her supportive potential.
