If you’re swinging a new weapon in Nioh 3 and wondering “why is this taking so long?” — you’re not alone.
Weapon leveling in Nioh 3 isn’t about grinding enemies for hours or chasing a specific build. It’s all about weapon familiarity. Once you understand how familiarity works, unlocking weapon skills becomes much faster and far less frustrating.
The key to leveling weapons fast is efficiency. Familiarity increases when you actively use a weapon and deal damage, not just when you finish missions. This means short, repeatable runs are far more effective than long story missions where progress feels slow.
To speed things up even more, players rely on items that boost familiarity directly. Whetstones are especially useful because they instantly increase weapon familiarity, allowing you to unlock skills much faster. When combined with quick farming runs, this method significantly reduces the time needed to level any weapon in Nioh 3.
Once your weapon gains familiarity, skills unlock naturally, letting you experiment with different playstyles without endless grinding. By focusing on familiarity, smart item use, and efficient runs, weapon leveling in Nioh 3 becomes simple, fast, and much more enjoyable.
First Things First: How Weapon Leveling Actually Works
Weapons in Nioh 3 don’t level up through character XP at all. Instead, they progress through something called weapon familiarity, which is what actually determines how fast you unlock weapon skills.
As your weapon’s familiarity increases, several important things happen. New weapon skills begin to unlock, the weapon itself becomes more valuable, and you move closer to fully maxing out that weapon type. This is why familiarity matters far more than enemy count or mission completion.
You gain familiarity simply by using the weapon. Dealing damage builds familiarity faster than just landing killing blows, so consistent combat matters more than one-shotting enemies. On top of that, certain items can boost familiarity directly, skipping a lot of the grind.
That last part — using items to increase familiarity — is the real game-changer and the key to leveling weapons quickly in Nioh 3.
The Fastest Method by Far: Whetstones
If you’re looking for the fastest possible way to level weapons in Nioh 3, whetstones are easily the best option. There’s nothing else that comes close in terms of pure speed and efficiency.
Each whetstone:
- Adds +150 weapon familiarity
- Applies instantly
- Has no downside, cooldown, or penalty
If you’re sitting on a stack of whetstones, you can skip large portions of the grind and push weapon familiarity forward in seconds instead of minutes.
How to Use Whetstones Properly
To get the most value out of them, keep it simple:
- Equip the weapon you want to level
- Use all available whetstones on that weapon
- Avoid swapping weapons until you’re finished leveling it
That’s all there is to it. No hidden tricks, no exploits, and no special setup required — just the most efficient and intended way to level weapons fast and unlock skills in Nioh 3.
Where to Get More Whetstones
You’ll earn whetstones naturally just by playing Nioh 3, but if you want to stock up faster, focusing on the right activities makes a big difference.
Whetstones commonly drop from enemies during short, repeatable missions, especially ones you can clear quickly. They also appear in small chests found along these routes, which is another reason fast runs are more efficient than long story missions. Crucible runs are another strong source, offering steady rewards and frequent reset opportunities. On top of that, general loot from quick clears can include whetstones, making speed the real priority.
The key takeaway is simple: short, repeatable content beats long missions every time. Faster resets mean more enemies, more chests, and more chances to pick up whetstones for faster weapon leveling.
No Whetstones? This Is the Next Best Option
If you’ve run out of whetstones, don’t worry — you can still build weapon familiarity through combat. The difference is that how you fight now matters a lot more than where you fight.
Familiarity increases faster when you deal steady, consistent damage rather than relying on one-shot kills. Landing repeated hits with the same weapon helps push familiarity up more reliably. Because of this, short fights that you can reset quickly are far more effective than long stretches of normal exploration.
This is exactly why certain modes and missions outperform open-ended areas. Fast, repeatable combat keeps familiarity climbing without wasting time, making it the best alternative when whetstones aren’t available.
Why Crucible Runs Are So Good for Weapon Leveling
Right now, Crucible runs are one of the best places to level weapons efficiently.
They work because:
- Enemy density is high
- Runs are short and repeatable
- You get good item and Amrita returns
- You’re constantly using your weapon
Simple Crucible Loop
- Equip your target weapon
- Use whetstones if you have them
- Clear Crucible floors normally — don’t rush past enemies
- Reset after a short run
- Repeat
You’ll build familiarity faster here than in most story missions.
Don’t Scrap High-Familiarity Weapons Yet
Once a weapon hits high familiarity, don’t instantly dismantle it.
Offering it at a shrine gives:
- Much more Amrita
- Better value than breaking it down
This creates a nice loop:
level weapon → offer at shrine → gain Amrita → clear faster → level next weapon.
Solo or Co-op: Which Is Better?
Both work, but they feel different.
Solo
- More consistent familiarity gain
- Easier to control damage output
- Better for focused weapon leveling
Co-op
- Faster clears
- More chaotic fights
- Better for general farming than targeted leveling
If your only goal is unlocking weapon skills, solo is usually the smoother option.
Quick Weapon Leveling Checklist
If you want a simple routine, use this:
- Equip the weapon you want to level
- Use all available whetstones
- Run a short Crucible or repeatable mission
- Focus on actually using the weapon
- Repeat until skills unlock
No build changes required.
Common Questions Players Ask
Do whetstones stack?
Yes. Every whetstone gives +150 familiarity, and you can use multiple in one go.
Is there a special build for weapon leveling?
No. Stats and builds barely matter here — items and mission choice do the heavy lifting.
Does damage matter for familiarity?
Yes. More consistent damage means faster familiarity gain.
Can I mess this up or miss weapon skills?
No. Nothing is permanently missable. You can always level weapons later.
Final Take
If weapon leveling in Nioh 3 feels slow, it’s not because you’re playing wrong — you just haven’t leaned into familiarity yet.
Use whetstones whenever you can, stick to short repeatable runs like the Crucible, and keep your focus on actually using the weapon you want to level. Do that, and weapon skills unlock way faster than just playing normally.
