MU Online Season 3 – Summoner, Master Level & Elbeland
Season 3 "Old Promise" (December 2007) and its Episode 2 follow-up (February 2008) form the most beloved version in MU's history — the classic six-class era that half the private-server scene still runs. It delivered three landmarks at once: the Summoner, the original Master Level skill trees, and the new territories Elbeland and Swamp of Peace. This guide rebuilds the whole season from the original patch notes.
Looking for a Season 3 server?
Season 3 servers appeal to players who want MU before the later power creep — the Summoner and the original Master Level system, without mastery gear or 4th and 5th class changes.

| Reason | Detail |
|---|---|
| The original Master Level | Season 3 introduced master levels and the first master skill tree, before the Season 6 renewal reworked it. |
| Simple progression | No mastery ladder, no artifacts, no ability cards. Gear tops out at ancient sets, so the gap between a new player and a veteran stays small. |
| The Summoner | Season 3 added the Summoner and her home town Elbeland — the last class added before the roster started expanding every season. |
| Low-rate friendly | Because the level ceiling and item pool are small, Season 3 suits slow, long-lived low-rate servers better than newer versions do. |
If Season 3 feels too bare, Season 6 is the natural next step — it keeps the classic feel but adds the Rage Fighter and the reworked master tree.
The Master Level System
Season 3's answer to the level 400 wall: characters with the 3rd class quest complete stop gaining normal levels and start earning master experience from any monster level 95+ on all maps. Each master level adds HP/MP/SD and grants 1 master point for the class skill tree.
| Rule | Original Season 3 value |
|---|---|
| Unlock | Level 400 + 3rd class change |
| Master exp source | Monsters level 95+ anywhere |
| Per level | +HP/MP/SD and 1 master point |
| Death penalty | 4% master exp; zen loss 0.7–4% (inventory + warehouse) scaling with murderer status |
| Seals | Ascension/Wealth-line seals usable but have no effect on masters |
The Four Trees
| Tree | Focus | Example skills |
|---|---|---|
| Defense | Defense rate (PvP), resistances | PvP defense rate +, Poison/Lightning/Ice resistance |
| Skill | Class skill power | Attack rate +, class skill strengtheners |
| Attack | Damage stats | PvP attack rate + |
| Growth / Utility | Quality of life | Durability reduction I/II, HP auto-recovery, zen gain + |
Each class got its own themed names for the four trees (the Blade Knight's Protection/Boldness/Rage/Hero line and equivalents). The structural rules defined the meta: ranks 1–8 upgrade in 5 stages each, deeper ranks need the previous rank finished — and the rank 9 finisher only activates after maxing rank 8 skills in two or more trees, forcing hybrid builds. The original four-tree window: Episode 2 expanded the trees with 7 common skills (defense +, max HP/AG, HP/mana/SD recovery on kill, exp +) and two strengtheners per class — Twisting Slash and Swell Life for Blade Knights, Soul Barrier for Soul Masters, Heal and Multi-Shot for Elves, Earthshake and Fire Burst for Dark Lords. The system's full modern evolution: Master skill tree guide.

The Summoner
MU's first new class since launch: a female mage from a reclusive race, starting in her sanctuary Elbeland. Class line: Summoner → Bloody Summoner → Dimension Master. Starting stats: STR 21, AGI 21, VIT 18, ENE 23 (70 HP / 40 MP).

| Playstyle | Original design notes |
|---|---|
| Solo | Smaller AoE than the Soul Master but fast kills through curse stacking; hungriest mana economy in the game |
| Party | The multiplier class — debuffs lower enemy stats for everyone; Energy Elf + Summoner was the designed dream duo |
| PvP | Debuff-then-burst; fragile against melee gap closers |
| Siege | AoE debuffs over enemy formations — her Castle Siege role ever since |
Skills & Summons
| Skill | Type | Effect |
|---|---|---|
| Drain Life | Attack | Steals enemy HP into your own |
| Chain Lightning | Attack | Three lightning hits chaining between targets (all three hit one lone target) |
| Damage Reflect | Buff | Reflect shield on self or allies, scaling with energy |
| Sleep | Curse | Puts an enemy to sleep until damaged |
| Weakness (Ep. 2) | Curse (AoE) | Lowers attack power of all enemies in range |
| Innervation (Ep. 2) | Curse (AoE) | Lowers defense of all enemies in range |
| Fireball, Power Wave, Meteorite, Ice | Shared | Borrowed from the Dark Wizard kit |
Curses never stack — a new curse overwrites the old one, and their success rate scales with the curse power of the equipped Book. The Books carry her two summons:
Sahamutt, the flame beast whose Explosion suicide-charge leaves burning damage-over-time, and
Neil, the blade saint whose Requiem opens bleeding wounds.

Summoner Exclusive Items
| Item | Type | Lore & notes | |
|---|---|---|---|
| Mystery Stick | Stick | Carved from the sacred Camillus tree, engraved with Semerun's ancient spell | |
| Violent Wind Stick | Stick | Heaven's Eye spirit stone core — every swing raises a gale | |
| Red Wing Stick | Stick | Phoenix-shaped, burning with flame energy | |

| Book of Sahamutt | Book (left hand) | Contract with the flame beast Sahamutt | |

Armor came as the Violent Wind, Red Wing and Ancient sets, and she shares low-tier gear (Kris, Short Sword, Rapier, axes, Skull Staff) with the classic classes. Her quest item
Abyssal Eye drives the 1st class-change quest.
| Wing | Original formula | |
|---|---|---|
| Wings of Curse (1st) | Level 180 + 4×wing level; DEF 10+3/lvl; DMG ±12+2/lvl; costs 1 HP per attack | |
| Wings of Despair (2nd) | Level 215 + 5×wing level; DEF 30+2/lvl; DMG +32, absorb 25+2/lvl | |
| Wings of Dimension (3rd, Ep. 2) | Level 400 + 4×wing level; DEF 45+4/lvl; DMG ±39+2/lvl |

Season 3 Item Stats — from the Game Files
The lore above is what Webzen shipped; these are the actual numbers, read from server item files. Drop level tells you which monsters can drop each piece — the practical farming order for a fresh Summoner.
Stick and Book Ladder
| Weapon | Drop Lv | Stats | Notes |
|---|---|---|---|
| 28 | Magic +34% · DMG 17–18 | Drops from level 28 monsters | |
| 42 | Magic +46% · DMG 23–25 | Level 42 drops | |
| 52 | Magic +46% · ENE 242 | First left-hand book | |
| 59 | Magic +59% · DMG 29–31 | Level 59 drops | |
| 59 | Magic +59% · ENE 332 | Mid-tier book | |
| 65 | Magic +72% · ENE 430 | Endgame book of the era | |
| 78 | Magic +76% · DMG 38–40 | Level 78 drops | |
| 100 | Magic +92% · DMG 46–48 | The Season 3 endgame stick |
Summoner Armor Sets
| Set | Pieces | Total defense | Farmed from |
|---|---|---|---|
| 5 pieces | 71 | Lv 24–34 monsters | |
| 5 pieces | 96 | Lv 44–56 monsters | |
| 5 pieces | 127 | Lv 61–75 monsters | |
| 5 pieces | 136 | Lv 60–91 monsters |
Each set exists in two visual variants with slightly different defense; the table shows the base variant. The full ladder with every piece is in the item database.
Skill Parchments
Summoner skills come from parchments rather than orbs and scrolls:
| Parchment | Requirement | Teaches |
|---|---|---|
| ENE 150 | Drain Life — damage that heals you | |
| ENE 180 | Sleep — disables a target | |
| ENE 245 | Chain Lightning — jumps between enemies | |
| ENE 300 | Explosion — area burst | |
| ENE 416 | Requiem | |
| ENE 300 | Darkness — the Curse Master toggle |
Elbeland – the Summoner's Home
A hidden sanctuary shielded by protective wards from Kundun's watchers. New Summoners spawn here, and it connects to the old world through two portals: Devias (24, 29) among the winter snows and Atlans (247, 149) by the waterfalls. Move costs: town 2,000 / Elbeland 2 2,500 / Elbeland 3 3,000 zen, level 10+.

New NPCs: Silvia (potions), Rhea (mid-tier weapons/armor) and Marce (magic goods) — and two Devias veterans relocated here: Mirage (Illusion Temple entry) and the jewel-combination NPC. Elbeland has been the Season 4+ hub for gens and elemental NPCs ever since.

Swamp of Peace (Episode 2)
The level 400+ hunting ground: islands around a central safe zone with portals at the 1, 5, 7 and 11 o'clock positions (15,000 zen entry via /move). Its nine monsters became the classic master-leveling targets:

| Monster | Lvl | HP | ATK | DEF | |
|---|---|---|---|---|---|
![]() | Sapi-Unus | 95 | 37,000 | 475–510 | 370 |
![]() | Sapi-Duo | 96 | 39,500 | 470–505 | 375 |

![]() | Shadow Rook | 104 | 47,000 | 650–680 | 500 |
![]() | Thunder Napin | 97 | 42,000 | 520–555 | 395 |

![]() | Blaze Napin | 107 | 52,000 | 670–725 | 525 |
The Sapi sisters — man-eating flowers luring prey with sweet scent — and the corrupted Napin tree spirits are still the first thing veterans picture when someone says "Season 3".
Master Event Maps
Season 3 added master-exclusive tiers of the classic events, with their own tickets:
| Event | Tier | Ticket mix | Success | Headline rewards |
|---|---|---|---|---|
| Devil Square | 7 | 45% | Up to 26,000 exp, 150,000 zen + 2M pool | |
| Blood Castle | 8 | 80% | 130,000 exp gates + Chaos; winner pool over 1M zen | |
| Chaos Castle | 7 | — | Bless/Soul jewels; classic 1st-place set-option drop | |
| Illusion Temple | 6 | 70% | 500,000 base exp + 13M zen pool |
Episode 2 Interface Extras
Small changes that stuck forever: the mini party window returned to the top-right, repair hotkeys L / Shift+L arrived, chat right-click set whisper targets, and quick-slot keys stopped firing mid-chat. If you have ever repaired with L on any server since 2008 — that is Season 3 Episode 2.
Barracks of Balgass
Season 3 Episode 2 introduced the Barracks of Balgass and the Refuge of Balgass — the two instanced maps used by the 3rd class change quest. You reach the Barracks from Crywolf and the Refuge through the Gatekeeper inside it.
Full monster stats, kill counts and the route between the two maps are in the 3rd class quest guide.

FAQ
Is this accurate for Season 3 private servers?
Yes — rebuilt from the original Webzen patch notes for Season 3 (Dec 2007) and Season 3 Episode 2 (Feb 2008). Individual servers tune rates and may rename maps (Swamp of Peace appears as Swamp of Tranquility/Serenity in some translations).
Which server version should I look for?
Season 3 Episode 2 is the definitive build — it includes the Summoner's full kit, Wings of Dimension, expanded master trees and Swamp of Peace. Browse Season 3 private servers currently open.
Can the Summoner use the master tree?
Yes — from Episode 2 onward, Dimension Masters got their own tree lines alongside the classic five.
What came next?
Season 4 (August 2008): the socket system, Raklion and master tree rank 4 skills — the start of the modern gear era.
