Mastery & Wen Guide - Project Slayers 2 Wiki
How weapon mastery levels work, how to farm Wen quickly, and what to spend both on for the best return.
Overview
Weapon mastery in Project Slayers 2 levels separately from your character, and hitting the level 255 cap does not finish your moveset. So mastery and Wen are the two grinds that keep running after the level bar stops, and this page covers how both work, how to farm them fast, and what is worth buying with the Wen you earn.
Max Mastery and Wen Farming
The video below walks through the fastest known method for stacking level, mastery and Wen at the same time, which is the most efficient way to play once the quest chains thin out. If you are still building your first character, read the leveling guide first and come back when the early brackets are behind you.
The Mastery Loop
Mastery moves only while you are swinging your equipped weapon, so idle time at a quest giver contributes nothing. Build a loop that keeps you in combat against enemies you can kill quickly, then reset instead of chasing a long fight that ends in a death. The fast leveling methods page covers the same route logic for XP.
Wen farming uses the same principle with one change: value per kill matters less than kills per hour, because drops and quest turn-ins both pay in Wen. Once your route is stable, spend a short session banking materials and a longer one converting them, so you are not running back to town after every pull.
Lock in one weapon
Mastery is tied to the weapon in your hands, so pick the katana you intend to keep and stop swapping every session.
Find a fast kill loop
Choose a dense group of enemies you can clear without risk and run the same circle until the pattern is automatic.
Bank Wen and materials
Sell what you do not need, keep Crude Iron for forging, and top up Bandages at 25 Wen before each long run.
Spend skill points on purpose
Skill points arrive per level and go into a per-style tree, so commit to a build instead of spreading them thin.
Reset only when it matters
A skill point reset exists through codes, so treat it as a planned rebuild rather than a fix for one bad choice.
What to Farm and What to Spend
The table splits the two currencies by what they actually buy. Wen is flexible and covers consumables, reforging and shop stock, while mastery is permanent progress you cannot purchase at any price. Knowing which one your build is short of tells you how to spend the next hour, and the progression guide shows where both fit in the wider path.
Treat this as a priority order rather than a shopping list. Consumables keep a farming run alive in the field, forging turns Crude Iron into real power, and cosmetic or low-impact purchases should wait until your dungeon build is already stable.
| Resource | How you get it | Best use |
|---|---|---|
| Wen | Quest turn-ins, enemy drops, codes | Bandages, consumables, reforging fees |
| Weapon mastery | Time spent fighting with one weapon | Unlocking the full moveset for that style |
| Skill points | One set earned per character level | Per-style tree, including block and utility |
| Crude Iron | Final Selection rewards | First forged breathing-style katana |
| Refinement Ore | Codes and late-game rewards | Weapon upgrades and reforging work |
Mastery, Damage and Diminishing Returns
Mastery is the slowest system by design. Character levels arrive from quests in bursts, while mastery only ever moves in proportion to the time you spend attacking, so a player who quests efficiently can still lag behind on moves. Treat mastery as a background grind you feed every session rather than a task you finish in one sitting.
Damage comes from stacked sources rather than one number. Clans, equipment, skill tree choices and mastery all feed the same output, and the boss encounters punish any build that ignores one of them. Check your damage against the same enemy after each change so you can tell which upgrade actually mattered.
Wen has a soft ceiling because the best gear is not purchasable. You cannot buy mastery, Crude Iron or boss drops, so the honest role of Wen is keeping you in the field with Bandages, consumables and forging fees while the real progression happens through breathing styles and combat time.
Wen Farming Principles
These four principles hold whether you are farming at level 20 or pushing the endgame. They are boring on purpose, because the players with millions of Wen are usually the ones who repeated a simple route instead of chasing the newest spot in chat. Start with the beginner guide if you are still learning the map.
Kills Per Hour
A weaker enemy you can clear instantly usually beats a tanky one that forces a retreat.
Sell the Clutter
Clear your inventory between runs so materials you never use still turn into Wen.
Forge, Do Not Buy
Crude Iron from Final Selection becomes a katana at the smith, which no shop can sell you.
Feed Mastery Daily
Even a short session with your main weapon keeps the slowest bar in the game moving.
Spending Priorities
When Wen finally stacks up, spend it in an order that protects your progress. Consumables and forging fees come first because they gate everything else, and low-impact purchases can wait until the build is finished. This list works at any level, and the active codes page covers the free Wen and ore that can jump-start it.
Keep a reserve instead of spending to zero. Dungeon runs and boss attempts both fail, and the players who recover fastest are the ones who still had Bandages and Wen when the attempt went wrong. A small buffer is worth more than a marginal upgrade.
- Bandages and consumables before any cosmetic purchase
- Forging fees for Crude Iron weapons as soon as Final Selection ends
- Refinement Ore for the weapon you actually use every session
- A standing Wen reserve for failed dungeon and boss attempts
Frequently Asked Questions
Does maxing level 255 finish my mastery?
No. Weapon mastery levels separately from your character, so reaching the level cap still leaves moves and passives to unlock with your equipped weapon.
What is the fastest way to farm Wen?
Pick a dense group of enemies you can clear without risk, run the same circle repeatedly, and sell unused materials between runs instead of hoarding them.
What should I spend Wen on first?
Bandages, consumables and forging fees come first. A failed dungeon or boss attempt costs far more than the upgrade you were saving for.
Can I buy mastery with Wen?
No. Mastery is earned only by fighting with a weapon, which is why it is the slowest bar in the game and keeps running after level 255.
How do skill points work?
You earn skill points as you level and spend them in a per-style skill tree, so plan a build instead of spreading points across every branch.
Where does Crude Iron come from?
Final Selection is the Crude Iron source. Take the material to the smith after the chain and it becomes your first forged breathing-style katana.
Is it worth farming Wen before endgame?
Only enough to stay stocked. Early Wen is better spent on consumables and forging, since the strongest weapons drop from bosses rather than shops.
