Fairy Elf Master Level Guide: Complete Mastery Tree
Complete Master Level guide for Fairy Elf (Muse Elf and High Elf) in MU Online S6: mastery tree, builds, farm spots, and stat allocation at every stage.
What is Master Level and How It Works for Fairy Elf
Master Level (ML) is the post-level-400 progression system in MU Online S6. Once your Fairy Elf reaches level 400, all experience gained converts into Master Level XP. Each ML rank earned grants 1 Mastery Point to distribute in your class Mastery Tree.
For the Fairy Elf, the Mastery Tree splits into four main branches:
- Attack Branch — increases bow damage, critical/excellent rates, Multi-Shot and Infinity Arrow
- Defense Branch — increases HP, physical defense, and elemental resistance
- Support Branch — strengthens Heal, Defense/Attack Buffs, and Holy Recovery
- Special Skills Branch — unlocks and upgrades Infinity Arrow and Rapid Arrows
Prerequisites Before Starting Master Level
Before entering the Mastery system, you need:
1 → Reach level 400 as a Fairy Elf (Muse Elf or High Elf)
2 → Complete the 3rd Class Quest to become High Elf (required for High Elf skills)
3 → Have minimum equipment to farm ML XP efficiently
4 → Have at least Wings L2 equipped (Wings of Spirits +0 already function)
Stat Allocation at Level 400
Before distributing Mastery Points, ensure your base stats are correct. Wrong base stat distribution cannot be undone without a full character reset.
High Elf AGI Build (Attack / PvM)
| Situation | STR | AGI | VIT | ENE | Notes |

| Level 400 (no reset) | 100 | 700 | 100 | remainder | ENE fills leftover points |
| Level 400 (1 reset) | 100 | 900 | 80 | remainder | High AGI for DPS and defense |
| Level 400 (2+ resets) | 80 | 1000 | 70 | remainder | Full AGI endgame |
Muse Elf Support Build (Party / Castle Siege)
| Stat | Value at Level 400 | Reason |
|---|---|---|
| STR | 80 | Minimum equipment requirement |
| AGI | 200 | Basic defense + attack speed |
| VIT | 300 | Survivability in siege scenarios |
| ENE | remainder (~820+) | Scales Heal HP and buff strength |

Daily ML Farm Routine
To maximize Master Level progression consistently:
1 → Log in + apply potions (Attack Potion, Defense Potion, Stamina Potion)
2 → Devil Square (daily event) → high ML XP per time invested
3 → Blood Castle (daily event) → XP + item drops
4 → Farm in Aida or Karutan for 2-3 hours with Infinity Arrow
5 → Chaos Castle (daily event) → additional XP
6 → Review day's drops and trade Jewels at Lorencia Market
Common Mistakes When Distributing the Mastery Tree
- Investing in elemental resistance nodes (Fire, Ice, Lightning) before maxing damage. Elemental resistance only matters in specific PvP matchups, never in PvM farm.
- Ignoring Stamina Increase: Infinity Arrow and Multi-Shot burn AG rapidly. Without points in Stamina Increase, you run out of AG mid-farm and lose significant DPS uptime.
- Over-investing in VIT: More than 20 points in the defense branch means less DPS. High Elf is not a tank — leave that role to the Blade Knight in your party.
- Not unlocking Infinity Arrow early on high-XP-rate servers: On servers with boosted XP rates, you accumulate ML quickly. Prioritize unlocking Infinity Arrow within the first 30 points so every farm session is immediately more efficient.
Perguntas frequentes
What is the difference between Muse Elf and High Elf in the Master Level system?
Both classes share the same Mastery Tree structure, but the High Elf (obtained after completing the 3rd Class Quest) has higher base stats and access to stronger scaling on attack nodes. The Muse Elf is better suited for a pure support build maximizing Heal Strengthening and Holy Recovery. High Elf can fully exploit AGI-attack branches including Infinity Arrow.
How many Mastery Points does Infinity Arrow require to unlock?
Infinity Arrow requires 10 points in the Infinity Arrow Unlock node. Before reaching it, you must invest: Multi-Shot Strengthening (5 pts minimum) → Triple Shot Strengthening (5 pts minimum) → Infinity Arrow Unlock (10 pts). Minimum total: 20 points spent in the chain before Infinity Arrow activates.
What is the best farm spot for Fairy Elf Master Level XP?
Aida open field is the top choice for an AGI High Elf using Infinity Arrow. Death Beam Knights (level 115) and Shadow Assassins (level 112) spawn in tight groups around coordinates 130, 150. With a Chaos Crossbow +13 and Wings L2+9, a High Elf with 500+ AGI clears spawns in seconds and accumulates ML XP efficiently.
Is it worth investing Mastery Points into VIT for a High Elf?
For an attack-oriented High Elf, no. Limit VIT investment to 10 points in Master Vitality Enhancement for basic survivability (+2,000 HP). All remaining points should go toward damage nodes (Bow Mastery, Critical Damage Rate, Excellent Damage Rate) or support nodes (Heal Strengthening, Defense Strengthening) depending on your role.
How do I get Wings L3 for Fairy Elf?
Wings of Eternal (Level 3 Wings) require: your existing Wings L2 + 3x Loch's Feather + 1x Jewel of Creation, combined in the Chaos Machine. Loch's Feather only drops from the boss Balgass — and only when the Crywolf event FAILS. Participate in Crywolf events but you need the defense to fail for the feathers to drop.
