As a dedicated Genshin Impact player since its early days, I've always been fascinated by how Bennett, often joked as the true Pyro Archon, can transform any team with his incredible buffs. Despite being a four-star character, his ability to amplify attack stats through his burst is unmatched, making weapon choice crucial—after all, his buff scales solely off base ATK, which means the sword he wields directly impacts the team's DPS. I've experimented with countless options over the years, and in 2025, some choices still stand out more than others, while others feel surprisingly niche. It's not just about raw numbers; the synergy with his role as a support can be tricky, leading to moments where I question if a high ATK stat is worth sacrificing Energy Recharge or other utilities. Let me share my experiences with these weapons, ranking them from least to most effective, based on how they perform in real battles across Teyvat.

8. Festering Desire

I remember getting this during that limited event years ago, and it felt like a treasure at first. With a base ATK of 510 and Energy Recharge substat at 45.9%, it helps Bennett maintain his burst uptime. But the passive, boosting Elemental Skill DMG and CRIT Rate by up to 32% and 12%, feels wasted on him—unless you're running a burst DPS build, which is rare. 😕 Honestly, it's a solid pick for nostalgia, but newer weapons have overshadowed it. The Sapwood Blade, for instance, offers more versatility without being event-exclusive. Here's a quick look at its stats:

Attribute	Value
Base ATK	510
Energy Recharge	45.9%
Passive Effect	Increases Elemental Skill DMG by 16-32%, CRIT Rate by 6-12%

Even with its decent ATK, I find myself rarely using it now, as it just doesn't bring enough to the table for a pure support Bennett.

7. Favonius Sword

This one's a staple for many support characters, and I've slapped it on Bennett more times than I can count. The Energy Recharge substat at 61.3% is fantastic for ensuring his burst is always ready, and the passive—generating Elemental Particles on CRIT hits—helps the whole team recharge faster. However, with only 454 base ATK, his buff feels noticeably weaker. ⚡️ In chaotic fights, it shines by letting my DPS units unleash their bursts more frequently, but I can't ignore how much ATK potential is lost. For players struggling with Energy issues, it's a lifesaver, yet it forces compromises in artifact builds. A table sums it up:

Attribute	Value
Base ATK	454
Energy Recharge	61.3%
Passive Effect	CRIT hits generate Elemental Particles, restoring 6 Energy

In teams where Energy is tight, this is a go-to, but I often swap it out when aiming for max buffs.

6. Blackcliff Longsword

As an F2P player myself, I appreciate how accessible this weapon is—just save up Starglitter, no gacha luck needed! It boasts a high base ATK of 565 and CRIT DMG substat at 36.8%, which adds a nice punch to Bennett's own attacks. The passive, increasing ATK by up to 24% after defeating enemies, is situational but can stack for extra DPS in mob-heavy domains. 🗡️ However, it doesn't directly enhance his buffing role, and in boss fights, it feels underwhelming. Why do I still recommend it? For its balance of ATK and ease of acquisition, making it a reliable choice for newer accounts. Key stats:

Attribute	Value
Base ATK	565
CRIT DMG	36.8%
Passive Effect	ATK increase by 12-24% after defeating opponents

It's not perfect, but in the Starglitter Shop, it's a solid investment.

5. Alley Flash

Here's a weapon that puzzles me—it has an Elemental Mastery substat of 55 and a passive that boosts damage by up to 24%, neither of which benefit Bennett much. Yet, it's one of his best four-star options, purely because of that whopping 620 base ATK! 🤯 Only 50 ATK shy of five-stars like Aquila Favonia, it maxes out his buff potential without needing pulls. I've used it in reaction-heavy teams, and while the passive is useless if he takes damage, the raw ATK makes up for it. For F2P players or those without gacha luck, this is a hidden gem. Stats overview:

Attribute	Value
Base ATK	620
Elemental Mastery	55
Passive Effect	Increases DMG by 12-24%, disabled for 5s on taking DMG

It's a prime example of how sometimes, one stat can carry a weapon.

4. Sapwood Blade

Crafted from Sumeru materials, this weapon has become a favorite of mine for Dendro teams. With base ATK at 565 and Energy Recharge substat of 30.6%, it keeps Bennett's burst consistent while its passive—generating a Leaf of Consciousness that grants up to 120 Elemental Mastery—boosts hypercarries like crazy. 🌿 In compositions like Thundering Furry or Spread teams, it amplifies reactions beautifully. I've seen my Ganyu Burnmet setups deal insane damage thanks to this. Plus, being refinable to R5 for free makes it a top F2P pick. Here’s the breakdown:

Attribute	Value
Base ATK	565
Energy Recharge	30.6%
Passive Effect	Creates Leaf for 60-120 EM after triggering reactions

For versatility and team synergy, it's hard to beat, even if the ATK isn't the highest.

3. Aquila Favonia

Ah, the classic—I recall when everyone hailed this as Bennett's ultimate weapon. Its base ATK of 674 is top-tier, and the passive offers ATK boosts up to 40%, plus healing and AoE damage. But let's be real: the Physical DMG Bonus substat at 44.3% is wasted on him, and the healing passive overlaps with his own kit. 🛡️ Still, that ATK stat alone makes his buffs massive. Over time, I've realized it's overrated for pure support; it shines only if you're building him hybrid. Stats highlight:

Attribute	Value
Base ATK	674
Physical DMG Bonus	44.3%
Passive Effect	ATK increase by 20-40%, heals and deals DMG on taking DMG

It's reliable for max buffs, but other options offer more utility.

2. Absolution

As Clorinde's signature weapon, I was skeptical at first, but wow, does it deliver! Tied for highest base ATK at 674, it also packs 44.1% CRIT DMG substat and a passive that increases DMG based on Bond of Life stacks. While Bennett isn't a hypercarry, the ATK boost elevates his buffs significantly. ⚔️ In my tests, it edges out Aquila Favonia because the CRIT DMG lets him contribute more personal damage. For teams needing extra oomph, it's a powerhouse, though Energy Recharge might need artifact tweaks. Key features:

Attribute	Value
Base ATK	674
CRIT DMG	44.1%
Passive Effect	CRIT DMG increase by 20-40%, DMG boost from Bond of Life

It's a luxurious choice that pays off in high-stakes battles.

1. Mistsplitter Reforged

Hands down, this is my top pick for Bennett in 2025. With the same 674 base ATK as Absolution and Aquila, it has a CRIT DMG substat of 44.1%, but its passive steals the show—granting up to 56% Elemental DMG Bonus and stacking buffs from Normal Attacks, Bursts, or low Energy. 🔥 On Bennett, it not only maxes his buff but also turns him into a sub-DPS monster, dealing Pyro damage that complements his kit perfectly. I've used it with Ayaka and Alhaitham teams, and the synergy is unreal. Just watch the Energy; if managed, it's unbeatable. Full details:

Attribute	Value
Base ATK	674
CRIT DMG	44.1%
Passive Effect	Elemental DMG Bonus up to 56%, stacks from attacks, burst, or low Energy

For those chasing peak performance, Mistsplitter is the crown jewel, blending buffing and damage in a way no other weapon does.

Reflecting on these, I'm struck by how much context matters—F2P options like Sapwood Blade can outshine gacha pulls in specific teams, while Mistsplitter's versatility makes it a universal winner. But it's not one-size-fits-all; your playstyle and artifact rolls can shift the rankings, leaving room for experimentation. What works for me might surprise you in your own adventures.
