So, you’re on the hunt for the best 4-star sword in Genshin Impact? Excellent choice! These versatile weapons can significantly boost your characters’ power without requiring the immense luck needed for 5-star pulls. While the “best” sword is heavily character-dependent, the Blackcliff Longsword and the The Black Sword generally reign supreme due to their impressive damage output and valuable passive abilities. However, the Favonius Sword, The Alley Flash, Festering Desire, and Sacrificial Sword can be even more potent depending on team composition, character role, and desired playstyle.

Diving Deep: A Character-Centric Approach

It’s crucial to understand that the most effective 4-star sword isn’t a one-size-fits-all solution. What works wonders for one character might be utterly useless for another. Let’s break down some top contenders and the characters they synergize with best.

Blackcliff Longsword: The Damage Dealer

The Blackcliff Longsword shines as a fantastic damage option. Its secondary stat is Crit DMG, which is a coveted stat for optimizing damage output. It also possesses a passive effect that increases ATK after defeating an enemy. This is particularly beneficial in domains and the Spiral Abyss, where you’re constantly facing waves of opponents.

Best Suited For: Characters who function as main DPS and benefit from high Crit DMG, such as Ayaka, Kaeya (DPS build), or even Bennett (DPS build).

The Black Sword: Sustained Offense and Survivability

This sword, obtained through the Battle Pass, stands out for its blend of offense and defense. It increases Normal and Charged Attack DMG and regenerates HP based on ATK. This makes your character more self-sufficient and reduces the reliance on healers (to some degree).

Best Suited For: Characters who heavily rely on Normal and Charged Attacks for damage, such as Geo Traveler, Keqing, or Ayato.

Favonius Sword: Energy Recharge and Team Support

The Favonius Sword is the premier energy-generating option for almost every character. Its secondary stat is Energy Recharge, and its passive has a chance to generate Elemental Particles on Crit hits, which can help the whole team get their Elemental Bursts up quicker. This can significantly improve team rotations and overall damage uptime.

Best Suited For: Characters who serve as Energy batteries and supports, such as Bennett, Jean, Xingqiu or even Kazuha. It’s also ideal for Travelers (especially Anemo Traveler) when focusing on Burst uptime.

The Alley Flash: Raw Attack Power

The Alley Flash sword has the highest base ATK of all 4-star swords, making it perfect for characters that scale with base attack. Its secondary stat is Elemental Mastery, and its passive increases DMG dealt.

Best Suited For: Characters who scale heavily on base ATK and appreciate the DMG buff, such as Bennett.

Festering Desire: Elemental Skill Powerhouse

This event-exclusive sword (no longer obtainable through normal means) boosts Elemental Skill DMG and Crit Rate. It also increases Energy Recharge, making it excellent for characters whose Elemental Skills are integral to their damage output.

Best Suited For: Characters who frequently use their Elemental Skill, such as Albedo (as a sub-DPS), Bennett, or Xingqiu. Although it is unavailable to new players, it remains a top-tier option for those who possess it.

Sacrificial Sword: Skill Reset Potential

The Sacrificial Sword has the Energy Recharge secondary stat, and it grants a chance to reset the cooldown of an Elemental Skill. This is invaluable for characters who have powerful or useful skills that they want to use more often.

Best Suited For: Characters who rely on their Elemental Skill for utility or damage and benefit from skill reset, such as Xingqiu, Bennett, or Kaeya.

Craftable Options: Accessible Power

Don’t overlook craftable 4-star swords! While they might not always be the absolute best, they’re accessible to all players.

Prototype Rancour: Physical DPS Focus

The Prototype Rancour is a solid choice for Physical DPS characters. It provides a Physical DMG bonus and increases ATK and DEF when dealing damage.

Best Suited For: Characters like Traveler or Kaeya (Physical DPS build).

Amenoma Kageuchi: Energy and Skill Damage

The Amenoma Kageuchi is crafted from Inazuma, and it is amazing on characters who are skill reliant because it can refund energy when using their elemental skill.

Best Suited For: Characters like Ayaka, or Bennett

The Importance of Refinement

Don’t forget about refinement levels! Increasing the refinement of a 4-star weapon can significantly boost its passive ability, making it even more effective. Farm those billets, and get those refinements up!

FAQs: Your Burning Questions Answered

What’s the best 4-star sword for the Geo Traveler?
- The Black Sword can be a solid choice due to its increased Normal and Charged Attack DMG, and its passive regenerating HP. However, for pure damage, the Blackcliff Longsword is also a great contender. The choice depends on your preferred playstyle.
Which 4-star sword is best for Kazuha?
- The Favonius Sword is often considered the best 4-star option for Kazuha, enhancing his energy regeneration capabilities. However, the Iron Sting crafted sword works well because it increases his elemental mastery, which is Kazuha’s main stat.
Is the Black Sword good for Kaeya?
- Yes, The Black Sword is a decent option for Kaeya, especially if you’re building him as a DPS. The increased Normal and Charged Attack DMG and HP regeneration are beneficial. The Blackcliff Longsword is a great pick for Main DPS as well.
What about F2P (Free-to-Play) options?
- The craftable Prototype Rancour (for Physical DPS) is a solid F2P choice. The Amenoma Kageuchi is also a good F2P choice.
Is the Royal Longsword any good?
- The Royal Longsword, obtainable through Starglitter Exchange, isn’t generally considered a top-tier option. Its passive ability, which increases Crit Rate after dealing damage, can be unreliable. There are better options in the 4-star pool.
What’s the best sword for Bennett?
- The Favonius Sword is generally considered the best for support Bennett due to the Energy Recharge substat and its particle generation. However, if you’re using him as a DPS, the The Alley Flash or the Blackcliff Longsword can be effective.
What is the rarest sword in Genshin?
- The Dark Iron Sword is considered the rarest weapon in Genshin Impact due to its limited availability.
How important is the weapon’s secondary stat?
- Very important! The secondary stat complements the weapon’s passive ability and should align with the character’s needs. For example, Crit DMG is excellent for DPS characters, while Energy Recharge is crucial for supports.
Should I prioritize refinement over a new weapon?
- It depends. Refinement can significantly boost a weapon’s passive, but a new weapon with a more suitable passive and secondary stat might be a better choice. Assess your characters’ needs and available resources.
What about event-exclusive weapons?
- Event-exclusive weapons, like Festering Desire, are often powerful due to their unique passives. If you have one, evaluate its potential on your characters.
Which 4-star sword is best for the Anemo Traveler?
- The Favonius Sword can be a solid choice due to its energy recharge.
Can I make a 4-star sword viable in the late game?
- Absolutely! With proper character builds, team compositions, and weapon refinements, 4-star swords can remain effective even in the late game.
Are there any 4-star swords that are never worth using?
- While most 4-star swords have a niche, some are generally less effective than others. Weapons like the Fillet Blade are generally less desirable due to their less impactful passives. However, everything depends on your team comp!
What is the best 4-star Claymore?
- Rainslasher is one of the best claymores in Genshin Impact despite being a 4-star. This is because it is especially effective against hydro and electro enemies.
What is the strongest sword in Genshin?
