Weapon power in Where Winds Meet comes from two steps that work together. You raise a weapon’s level with coins and basic materials, then you clear breakthroughs to lift the level cap and unlock stronger effects. The slow part is almost always the breakthrough notes, so the fastest route is knowing exactly where those notes come from and stocking up before you hit a wall.
Quick answer: Level a weapon with coins in the Martial Arts menu until it reaches its cap, then spend weapon-specific notes to break through. Get those notes fastest by buying Martial Arts: Custom Notes chests with Jade Fish in the Season Shop and by farming the exact note from Campaign Challenge bosses in Wandering Paths.
How weapon leveling works
Every weapon uses two upgrade tracks. Standard leveling costs coins and developmental materials such as Bluestone Locks, and it pushes the weapon up until it hits a level cap. That cap does not move until you complete a breakthrough. Breakthroughs unlock martial arts talents, add stat boosts, and raise the cap so you can keep leveling.
You can see your current build and equipped weapons from the Gear menu, which is useful for checking average level before you decide what to pour resources into.
Coin upgrades are cheap and fast. The real cost sits at the breakthrough gates, where you need notes tied to that specific weapon. Because of this, coins are rarely the bottleneck. Notes are.
Breakthrough notes and what each tier costs
Each weapon breaks through using its own note type. A Bamboocut weapon needs Wind Notes, a Bellstrike weapon needs Umbra Notes, a Silkbind weapon needs Deluge Notes, and so on. You cannot substitute one weapon’s note for another.
Costs climb sharply at the top end. Early breakthroughs ask for small stacks, but the highest tiers demand a lot. Pushing a weapon from level 95 to 100 can require up to 96 notes for that single step, which is why late upgrades feel so much slower than early ones.
| Item | Purpose |
|---|---|
| Coins | Standard weapon level upgrades |
| Bluestone Lock | Developmental material used in upgrades |
| Weapon-specific note (e.g. Wind, Umbra, Deluge) | Required to clear each breakthrough tier |
| Martial Arts: Custom Notes chest | Season Shop chest that yields notes |
Season Shop: the biggest note source
The Season Shop is the most reliable way to stockpile notes because it sells Martial Arts: Custom Notes chests for Jade Fish. These chests convert into the note type you need, so buying them weekly keeps a steady supply flowing toward whatever weapon you are pushing.
Season Catch-up Shop for extra chests
If the weekly Season Shop limit is not enough, the Season Catch-up Shop stocks additional Custom Notes chests. This is the place to check when you have burned through your standard allowance and still need more notes to clear a tier.
Farm exact notes from Campaign Challenges
When you need a very specific note fast, target Campaign Challenge bosses in Wandering Paths. Certain bosses drop the exact note tied to a weapon, so you can farm straight toward the type you are short on instead of relying on chest luck.
The fastest routine, in order
Combine the sources instead of leaning on just one. Buy your weekly Custom Notes chests every reset, push toward the 10,000 Jade Fish threshold to unlock the extra 40 chests, and top off any gap with Catch-up Shop chests. When you need a single note type in bulk, spend Energy on the matching Wandering Paths boss at the 3x multiplier.
| Source | What it gives | Key detail |
|---|---|---|
| Season Shop | Custom Notes chests for Jade Fish | 15 weekly (up to 30 stock); +40 after 10,000 Jade Fish in a week |
| Season Catch-up Shop | Extra Custom Notes chests | Use when the weekly limit runs out |
| Campaign Challenges (Wandering Paths) | The exact note a boss drops | 20 Energy per claim; 60 Energy at 3x for 6 notes |
You will know an upgrade landed when the weapon’s cap rises and the breakthrough tier shows as cleared on the Martial Arts screen, along with the new talents and stat boosts it unlocks. If a breakthrough will not confirm, the usual cause is simply not holding enough of that weapon’s note. Keep coins in reserve for the level-up track, but treat notes as the resource that decides how fast a weapon reaches its ceiling.
