Slayer 2 Mastery unlocks and upgrades your weapon, Breathing Technique, or Evil Art abilities, but the fastest farming method depends on your player level.
| Method | Best Level | Efficiency |
|---|---|---|
| Crow/Muzan Boss Quests | 225 (max) | Excellent |
| Dungeon Points Exchange | 65β225 | Good |
| Tier 3 Chest Guards | Mid-game | Moderate |
| Ranked PvP | Any (with access) | Moderate |
Here’s my full October 2026 route from level 65 all the way to max Mastery, based on the current level-225 cap.
Don’t force Mastery farming while you’re still under-leveled. Grind the normal quest chain to level 225 first β at the cap, EXP from Crow and Muzan quests converts directly into Mastery instead, making your existing quest rotation far more efficient.
Slayers get the Kasugai Crow after Final Selection; Demons use their Bell to reach Muzan. Both open around level 125, when world bosses start appearing in the quest pool. Before that, you’ll mostly fight trainees, so treat early quests as level-up fuel rather than a Mastery source.
Crow and Muzan rewards scale with how many high-level players from your race are active in the server. Slayers want servers full of strong Slayers; Demons want strong Demons. More population also means more competition, so check your quest menu’s reward numbers before committing β an empty private server won’t automatically give you the best rate either.
At 225 on a good server, boss quests become your main grind: accept, travel, kill, turn in, repeat. Use unlocked shrines to cut travel time, and prioritize bosses you can kill quickly over ones with a bigger reward but a longer fight. If you’re farming with a stronger friend, stay active in the fight so you get credit.
Scout your server, confirm quests are available, and map your boss route before popping a Double Mastery Potion β you want to farm continuously the second it activates. If you’re still under 225, save these and use Double EXP Potions instead.
Below max level, or without a strong server, Dungeons are your best bet. Unlock them at level 65 after the Forge quest, then run Normal difficulty (three lives) for consistent points rather than Ranked (one life, leaderboard-focused).
| Dungeon Points | Mastery |
|---|---|
| 3,500 | 1,000 |
| 35,000 | 10,000 |
Early floors, prioritize damage cards to clear fast; later floors, lean into survival and cooldown cards. Once your build is solid, shift toward point and fortune cards for maximum exchange value.
Not strong enough for bosses or Dungeons yet? Fight the enemies guarding Tier 3 chests around the Tundra. You get Mastery and chest loot, making this a solid mid-game grind. Bring a partner if the guards are tough, and stay active in the fight for credit.
Wins reward Mastery too, but efficiency depends on your win rate and queue times. Treat PvP as a change of pace, not your primary farming method, unless you’re already grinding Ranked anyway.
You want to be at the level cap (225) since Crow and Muzan quest EXP converts to Mastery rewards at that point.
Dungeons are the best pre-225 option β run Normal difficulty and exchange Dungeon Points for Mastery.
Yes. Crow and Muzan quest rewards scale with how many high-level players of your race are in the server, so populated servers generally pay out more.
Only as a secondary method β quest farming and Dungeons are more consistent than relying on PvP wins.
