When talking about support characters in Genshin Impact, you'll definitely hear about Furina, Bennett, and Kazuha. Interestingly, all three of these top support characters use swords as their weapon.

Xilonen, a new character introduced in version 4.1, also wields a sword. She’s a great support character, but her buffs don’t rely on specific stats—they're flat and depend on her Skill level. Still, equipping her with the best weapons in Genshin Impact is a good idea, especially if the sword provides extra support or offensive effects to enhance her role in battle.

1. Peak Patrol Song

  • Primary Stat: 542 Base ATK
  • Secondary Stat: 82.7% DEF
  • R1 Effect: When you hit an opponent with Normal or Plunging Attacks, you gain "Ode to Flowers," which increases your DEF by 8% and grants a 10% All Elemental DMG Bonus for 6 seconds. You can stack this effect up to 2 times, and it can trigger once every 0.1 seconds. If you reach 2 stacks or refresh the duration of the second stack, all nearby party members receive an All Elemental DMG Bonus of 8% for every 1,000 DEF the character has, up to a maximum of 25.6%, lasting for 15 seconds.

The Peak Patrol Song is the best weapon for Xilonen. It boosts both her DPS and DEF while offering a supportive passive. For maximizing both her damage and support capabilities, this sword is the ideal choice.

2. Uraku Misugiri

  • Primary Stat: 542 Base ATK
  • Secondary Stat: 88.2% Crit DMG
  • R1 Effect: Normal Attack DMG is boosted by 16%, and Elemental Skill DMG is increased by 24%. When a nearby active character deals Geo DMG, these effects double for 15 seconds. Plus, the wielder's DEF is raised by 20%.

Since both Chiori and Xilonen are DEF-Geo characters, Chiori's weapon is an excellent choice for enhancing Xilonen's DPS.

3. Flute of Ezpitzal

  • Primary Stat: 454 Base ATK
  • Secondary Stat: 69.0% DEF
  • R5 Effect: Activating an Elemental Skill raises DEF by 32% for 15 seconds.

In contrast to Cinnabar Spindle, Flute of Ezpitzal is very easy to obtain since it’s one of the five forgeable weapons in Genshin Impact's Natlan. Just visit the local blacksmith to get the blueprint and craft the sword.

4. Haran Geppaku Futsu

  • Primary Stat: 608 Base ATK
  • Secondary Stat: 33.1% Crit Rate
  • R1 Effect: You gain a 12% All Elemental DMG Bonus. When nearby party members use Elemental Skills, the character with this weapon earns 1 Wavespike stack, with a maximum of 2 stacks. This effect can trigger once every 0.3 seconds. When the character uses an Elemental Skill, all Wavespike stacks are consumed to grant Rippling Upheaval, increasing Normal Attack DMG by 20% for 8 seconds for each stack used.

Players using Xilonen as a DPS would ideally want 5-star weapons that boost Critical Rate and DMG, and among those, Haran Geppaku Futsu stands out. Since DPS Xilonen relies heavily on her Normal Attacks, Ayato’s signature weapon is a great match for her.

5. Cinnabar Spindle

  • Primary Stat: 454 Base ATK
  • Secondary Stat: 69.0% DEF
  • R5 Effect: Elemental Skill DMG is boosted by 80% of DEF. This effect can trigger a maximum of once every 1.5 seconds and will reset 0.1 seconds after the Elemental Skill deals damage.

Xilonen requires DEF for both her damage and healing, making DEF-focused weapons like Cinnabar Spindle great options for her. Unfortunately, this sword is only available to players who participated in the event during version 2.3, so not everyone can access it.

6. Freedom-Sworn

  • Primary Stat: 608 Base ATK
  • Secondary Stat: 198 Elemental Mastery
  • R1 Effect: This weapon is part of the "Millennial Movement" that travels with the winds and increases DMG by 10%. When the character wielding it triggers Elemental Reactions, they gain a Sigil of Rebellion, which can occur once every 0.5 seconds, even if the character is off the field. When you have 2 Sigils of Rebellion, they are consumed to grant all nearby party members "Millennial Movement: Song of Resistance" for 12 seconds. This effect boosts Normal, Charged, and Plunging Attack DMG by 16% and increases ATK by 20%. After this effect activates, you won’t gain any more Sigils of Rebellion for 20 seconds. Note that buffs of the same type from the "Millennial Movement" will not stack.

While Xilonen doesn't specifically require Elemental Mastery, Freedom-Sworn is still a great sword for support characters overall. She can easily trigger Elemental Reactions, particularly Crystallized, while attacking enemies.

7. Favonius Sword

  • Primary Stat: 454 Base ATK
  • Secondary Stat: 61.3% Energy Recharge
  • R5 Effect: CRIT hits guarantee the generation of a small amount of Elemental Particles, restoring 6 Energy for the character. This effect can activate only once every 6 seconds.

When thinking about weapons for a support character, Sacrificial and Favonius weapons come to mind. For Xilonen, the Favonius Sword is ideal for providing Energy Recharge and enabling her to function as a Battery in Genshin Impact. Just remember to equip a Crit Rate Circlet to effectively trigger its passive.

8. Harbinger of Dawn

  • Primary Stat: 401 Base ATK
  • Secondary Stat: 46.9% CRIT DMG
  • R5 Effect: When HP is above 90%, CRIT Rate is increased by 28%.

This 3-star weapon in Genshin Impact is surprisingly powerful. It offers a high Crit Value despite its low Base ATK. Fortunately, characters like Albedo and Xilonen, who don't rely on ATK scaling, can benefit from it without concern. As a result, Harbinger of Dawn is one of the top choices for DPS Xilonen. If players can maintain full uptime on its passive, it could even outperform some 5-star weapons.
