When you're building a main damage dealer in Genshin Impact, the usual drill is to stack Attack like there's no tomorrow, alongside those precious Crit stats. But Arataki Itto, the one and oni, plays by his own rules. For him, Defense isn't just about being tough—it's his primary source of power. His Elemental Burst and passive talents convert that sturdy DEF into devastating Geo damage, turning him from a wall into a wrecking ball. As a Geo Claymore wielder, finding the perfect weapon to complement his unique scaling can be a head-scratcher, especially with his signature weapon being a limited banner prize. Fear not, for there are plenty of excellent alternatives to make Itto hit like a truck. Let's dive into the arsenal.

7. Verdict

Rarity Secondary Stat
Five Star Crit Rate

Don't let the low ranking fool you—any five-star weapon is a force to be reckoned with. Seeing Verdict, the signature weapon for another Geo Claymore user, so far down the list might raise an eyebrow. Honestly, it's a bit of a square peg in a round hole for Itto. It brings a hefty chunk of Crit Rate to the table, which is always welcome, and its passive boosts Skill Damage. The problem? It also grants an ATK bonus, which, while nice, doesn't give our DEF-scaling oni the same explosive payoff. It's a solid stat stick, but it doesn't sing in harmony with Itto's kit like his true signature does. You could do worse, but you could also do a lot better.

6. The Unforged

Rarity Secondary Stat
Five Star ATK Percent

Talk about an ironic name for a weapon that had to be forged, right? The Unforged makes up for its philosophical quandary with pure battlefield prowess. Its passive is all about hitting hard and staying safe. It boosts shield strength right off the bat and grants an ATK bonus with every strike against an enemy. The real kicker? If the wielder is cozy behind a shield, that ATK bonus gets doubled. This turns defense into offense in a very literal way. For Itto, who often runs alongside shielders like Zhongli to ensure his powerful charged attacks aren't interrupted, this weapon becomes a perfect partner in crime. It teaches you good habits: keep the shield up, and watch the numbers go up.

5. Skyward Pride

Rarity Secondary Stat
Five Star Energy Recharge

This weapon looks like it wandered out of a fantasy epic, and it brings some epic utility. Skyward Pride solves one of Itto's few potential hiccups: Energy. Its high base ATK is great, but the real star is the Energy Recharge secondary stat. It makes getting Itto's expensive Elemental Burst back a breeze—almost too easy, some might say. After unleashing his Burst, his normal and charged attacks will trigger vacuum blades that slice through enemies based on his ATK. While the DMG bonus from the passive is the main attraction for boosting his overall output, the comfort of having his ultimate ready on cooldown is priceless. Pairing this with an artifact set like the Emblem of Severed Fate can turn him into a non-stop Geo cannon.

4. Wolf's Gravestone

Rarity Secondary Stat
Five Star ATK Percent

The old reliable. Wolf's Gravestone is a classic for a reason. It doesn't specifically synergize with Itto's DEF-scaling mechanics—it's just a brutally effective weapon that makes anyone holding it hit harder. It provides a flat ATK increase to the user and, when striking a low-health enemy, buffs the entire party's ATK. So, while it doesn't directly amplify Itto's unique strengths, it still significantly boosts his raw damage and turns him into a team player, buffing your sub-DPS characters as well. It's a fantastic choice for teams where you might have another damage dealer ready to step in when Itto's Burst is cooling down. Sometimes, simple and strong is the way to go.

3. Whiteblind

Rarity Secondary Stat
Four Star DEF Percent

Now we're talking Itto's language! Whiteblind is the people's champion, the craftable wonder. This weapon is straightforward and brilliant for him. Its secondary stat is DEF Percent, already a perfect match. Its passive is even better: on hit, Itto's normal and charged attacks grant him a stacking boost to both his ATK and DEF. For a character whose damage scales directly from DEF, this is a double-dip delight—it fuels his primary stat and gives him a direct damage boost. The best part? You can forge it yourself! No wishing required, just a Northlander Claymore Billet and some mining time. It may not have the flashy looks of a gacha weapon, but in Itto's hands, it's an absolute workhorse.

2. Serpent Spine

Rarity Secondary Stat
Four Star Crit Rate

This weapon is a high-risk, high-reward masterpiece from the Battle Pass. Serpent Spine offers a massive, stacking DMG bonus. The catch? You take more damage, and if you get hit, you lose all those precious stacks. Ouch. To make this weapon truly sing for Itto, you need a top-tier shielder—like Zhongli—watching his back. You can't rely on flimsy Crystallize shields here; you need an impenetrable fortress. But if you can manage that, and especially if you've maxed it out to Refinement Five over several Battle Pass seasons, the damage output is nothing short of staggering. The Crit Rate secondary stat also makes building him a dream. It's a weapon that rewards skill and team synergy.

1. Redhorn Stonethresher

Rarity Secondary Stat
Five Star Crit DMG

Of course, the king of the hill. Redhorn Stonethresher isn't just Itto's best weapon; it feels like it was custom-forged for him (and, well, it was). This is the perfect synergy weapon. It boosts DEF significantly and then takes that DEF and converts it directly into extra damage for his normal and charged attacks. It's the definition of "scaling with his kit." On top of that, it comes with a monstrous 88.2% Crit DMG bonus at level 90, which takes immense pressure off your artifact farming. Getting it, however, is the real challenge—it's only available on limited weapon banners, so you'll need a hefty stash of Primogems and a sprinkle of luck. But if you manage to get it, it transforms Itto from a powerful DPS into an unstoppable Geo juggernaut. The difference is, frankly, night and day.

Final Thoughts

Choosing Itto's weapon in 2026 still comes down to understanding his core mechanic: DEF is king. While flashy ATK-boosting swords can work, the weapons that truly unlock his potential are those that embrace his stony durability. From the accessible power of Whiteblind to the disciplined might of Serpent Spine, and all the way to the pinnacle that is Redhorn Stonethresher, there's a perfect claymore out there for every level of investment. So, pick your tool, build that DEF, and let the one and oni do what he does best—smash everything in sight.
