In Genshin Impact, using an optimized build for Xilonen can greatly enhance her role as a versatile support unit, both on and off the field. Xilonen is a 5-star Geo character who wields a sword, making her first appearance as a playable unit in Version 5.1, which coincides with the second update for the Natlan region. Along with new story content, Xilonen will appear as an ally to Mavuika, the Pyro Archon, in the Genshin Impact narrative.

If you need a lot of Primogems to get Xilonen, I suggest you find a reliable website like Z2U to buy affordable Genshin Impact Primogems, which will save you a lot of money. As a playable character, Xilonen excels in the support role, particularly through her ability to shred enemy resistance based on team composition. This RES reduction makes enemies more susceptible to Elemental DMG from her allies, allowing main DPS and sub-DPS characters to deal increased damage. Beyond her supportive capabilities, Xilonen can also deal damage herself and provide healing to her team through her Elemental Burst. After fully leveling her up, players should focus on building Xilonen in a way that maximizes her supportive and healing abilities to boost her overall performance.

Best Weapons for Xilonen

Choosing the right weapon is critical for Xilonen’s build. Her best weapon is her signature 5-star sword, Peak Patrol Song, which offers a balanced base ATK stat of 542 (at level 90) and an impressive 82.6% DEF sub-stat. When Xilonen lands a Normal or Plunging Attack, she gains the Ode To Flowers buff, increasing her DEF by 8% and providing a 10% Elemental DMG bonus for six seconds, stacking up to two times. At two stacks, the buff also increases all nearby party members' Elemental DMG based on Xilonen’s DEF, further enhancing her team’s damage output.

If Peak Patrol Song is not available, another strong 5-star alternative is Freedom-Sworn. This sword has a higher base ATK (608 at level 90) and a valuable Elemental Mastery sub-stat (198 at level 90). Freedom-Sworn boosts Xilonen’s DMG by 10% and generates Sigils of Rebellion when Elemental Reactions are triggered. With two Sigils, nearby allies receive a 20% ATK boost and enhanced Normal, Charged, and Plunging Attack DMG, further empowering the team’s offensive capabilities.

For players without access to these 5-star weapons, several viable 4-star options exist. The best 4-star sword for Xilonen is the Flute of Ezpitzal, which provides a moderate base ATK (454 at level 90) and a significant 69% DEF sub-stat. This sword increases Xilonen’s DEF by 16% for 15 seconds when her Elemental Skill is activated. Another solid choice is the Cinnabar Spindle, which also boosts DEF and increases Elemental Skill DMG by 40% of Xilonen’s DEF. Lastly, the Favonius Sword can be considered due to its Energy Recharge sub-stat (61.3% at level 90) and its ability to generate Energy for the team.

Best Artifacts and Stats for Xilonen

To maximize Xilonen’s support potential, the ideal Artifact set is the four-piece Scroll of the Hero of Cinder City. The two-piece bonus grants 6 Elemental Energy when a nearby ally triggers a Nightsoul Burst, while the four-piece bonus increases Elemental DMG for the team when Elemental Reactions are triggered. If Xilonen is in the Nightsoul’s Blessing state, this effect can provide up to a 40% Elemental DMG bonus for the team, making it an invaluable set for her.

In terms of stats, DEF and Energy Recharge should be prioritized to ensure Xilonen can consistently use her skills and bursts. Players may also consider increasing Healing Bonus to improve her healing abilities, or CRIT Rate and CRIT DMG to boost her personal damage output, though these are secondary considerations.

Best Team Comps for Xilonen
Xilonen’s versatility as a support character allows her to fit into a wide variety of team compositions, though she is less effective in mono-Geo teams. She can be an excellent support for characters like Neuvillette, enhancing his Hydro DMG and reducing enemy Hydro RES. Xilonen can also synergize well with Navia, as long as there is a sub-DPS of a different Elemental Type to trigger reactions that activate her Artifact set bonuses.

Although Xilonen shares some similarities with Kazuha in terms of support capabilities, pairing them together in hypercarry teams can result in surprisingly powerful synergies. She can also function in teams that focus on a single Elemental Type, such as those led by Pyro DPS characters. If Xilonen’s healing isn’t sufficient, she can be paired with secondary supports who offer more robust healing, like Bennett or Furina, ensuring that the team’s HP remains topped off while maximizing damage potential.

By optimizing Xilonen’s build with the right weapons, artifacts, and team comps, players can fully harness her ability to support their teams with RES shred, DMG boosts, and healing, making her a valuable asset in a variety of scenarios in Genshin Impact. At the same time, if you want to have a Genshin Impact Account with more powerful characters, you can choose freely on Z2U, which guarantees you the best gaming experience.
