With Xilonen’s rerun starting today, it’s the perfect time to optimize her build. Whether you’re pulling her for the first time or refining her setup, here’s a comprehensive guide to her playstyle, best artifacts, weapons, and team compositions.​

Also, full disclosure—Xilonen’s easily one of my favorite characters. From her aesthetic to her kit, everything about her just works, and I genuinely think she is one of the coolest characters.

Playstyle Overview: Support & Off-Field Utility

Xilonen excels as a DEF-scaling support who enhances team damage through Elemental RES reduction and healing. Her Elemental Skill, Yohual’s Scratch, applies a Nightsoul mark that reduces enemy Elemental RES, while her Burst provides healing and further buffs. She shines in reaction-heavy teams, offering consistent off-field utility.​

Best Artifact Sets

1. Scroll of the Hero of Cinder City (4-piece)
This set is ideal for Xilonen’s support role. The 2-piece bonus aids energy regeneration, while the 4-piece effect grants a significant Elemental DMG Bonus to the team after triggering reactions. It’s especially effective when Xilonen is in the Nightsoul’s Blessing state.

2. Noblesse Oblige (4-piece)
A solid alternative if another character is using the Scroll set. It boosts team ATK after Xilonen uses her Burst, complementing her support capabilities.

3. Obsidian Codex (4-piece)
For a more DPS-oriented build, this set increases Xilonen’s on-field damage, especially when consuming Nightsoul points.

Main Stats:

• Sands: DEF% or Energy Recharge
• Goblet: DEF%
• Circlet: Healing Bonus, DEF%, or CRIT Rate (if using Favonius Sword)​

Substat Priority:

• DEF%
• Energy Recharge
• CRIT Rate (for Favonius Sword users)

Best Weapons

1. Peak Patrol Song (5★)
Xilonen’s signature weapon, it offers a substantial DEF boost and increases Elemental DMG for both her and the team based on her DEF.

2. Favonius Sword (4★)
A great support option, especially in solo Geo teams, providing Energy Recharge and generating energy particles on CRIT hits.

3. Flute of Ezpitzal (4★)
A free-to-play friendly choice, this forgeable weapon significantly boosts DEF after using an Elemental Skill, aligning well with Xilonen’s scaling.

4. Cinnabar Spindle (4★)
Offers a high DEF substat and increases Elemental Skill damage based on DEF, suitable for a more damage-focused build.

Best Team Compositions

Xilonen fits seamlessly into various team setups, enhancing Elemental Reactions and providing support.​

1. Vaporize Team:

• Main DPS: Mualani
• Sub DPS: Xiangling
• Support: Xilonen
• Shield: Zhongli

This team focuses on consistent Vaporize reactions, with Xilonen reducing enemy RES and healing.

2. Geo Support Team:

• Main DPS: Arataki Itto
• Sub DPS: Albedo
• Support: Xilonen
• Healer: Gorou​

Leveraging Geo synergy, Xilonen enhances team damage and provides healing, fitting well into mono-Geo compositions.​

3. My Personal Xilonen Team:

• Main DPS: Neuvillette
• Sub DPS/Buffer: Furina
• Support: Xilonen
• CC/Buffer: Kazuha

Both Kazuha and Xilonen reduce enemy resistance, while Furina adds extra Hydro application and a teamwide damage buff—perfect for boosting Neuvillette’s overall damage output.

Final Tips

• Energy Recharge: Aim for 140–180% to ensure consistent Burst uptime, especially in solo Geo teams.
• DEF Focus: Prioritize DEF in both main stats and substats to maximize Xilonen’s support capabilities.
• Weapon Choice: While her signature weapon is optimal, Favonius Sword and Flute of Ezpitzal are excellent alternatives.

With the right build, Xilonen becomes a versatile support, enhancing team damage and survivability. Her rerun offers a great opportunity to add a unique and powerful character to your roster.
