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.

Why People Still Play Season 3

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.

Weakness (Ep. 2)	Innervation (Ep. 2)	Wings of Dimension

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
	Ancient Stick	Stick	Relic of the spirit-callers who predate the MU continent
	Book of Sahamutt	Book (left hand)	Contract with the flame beast Sahamutt
	Book of Neil	Book (left hand)	Contract with the blood saint Neil

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
Mystery Stick	28	Magic +34% · DMG 17–18	Drops from level 28 monsters
Violent Wind Stick	42	Magic +46% · DMG 23–25	Level 42 drops
Book of Shamut	52	Magic +46% · ENE 242	First left-hand book
Red Wing Stick	59	Magic +59% · DMG 29–31	Level 59 drops
Book of Neil	59	Magic +59% · ENE 332	Mid-tier book
Book of Lagle	65	Magic +72% · ENE 430	Endgame book of the era
Ancient Stick	78	Magic +76% · DMG 38–40	Level 78 drops
Demonic Stick	100	Magic +92% · DMG 46–48	The Season 3 endgame stick

Summoner Armor Sets

Set	Pieces	Total defense	Farmed from
Violent Wind Set	5 pieces	71	Lv 24–34 monsters
Red Wing Set	5 pieces	96	Lv 44–56 monsters
Ancient Set	5 pieces	127	Lv 61–75 monsters
Demonic Set	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
Drain Life Parchment	ENE 150	Drain Life — damage that heals you
Sleep Parchment	ENE 180	Sleep — disables a target
Chain Lightning Parchment	ENE 245	Chain Lightning — jumps between enemies
Explosion Parchment	ENE 300	Explosion — area burst
Requiem Parchment	ENE 416	Requiem
Darkness Parchment	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+.

Elbeland — original concept art	The Elbeland world map

	Monster	Lvl	HP	ATK	DEF
	Strange Rabbit	4	60	10–13	3
	Polluted Butterfly	13	230	37–42	13
	Hideous Rabbit	19	520	68–72	22
	Werewolf	24	720	85–90	30
	Cursed Lich	30	900	105–110 (fire, ranged)	33
	Totem Golem	36	1,200	120–125 (AoE, slow)	50
	Grizzly	43	2,400	130–145 (ranged packs)	65
	Captain Grizzly	48	3,000	150–155	80

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.

Silvia — potions	Rhea — weapons & armor	Marce — magic goods

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
	Sapi-Tres	102	45,500	590–625	470
	Shadow Pawn	98	43,000	540–575	425
	Shadow Knight (ice)	100	44,000	570–600	445
	Shadow Rook	104	47,000	650–680	500
	Thunder Napin	97	42,000	520–555	395
	Ghost Napin	106	48,000	655–685	535
	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	Eye +7 & Key +7 (lvl 90+ drops) + Chaos	45%	Up to 26,000 exp, 150,000 zen + 2M pool
Blood Castle	8	Cloak +8 mix (lvl 90+ scrolls)	80%	130,000 exp gates + Chaos; winner pool over 1M zen
Chaos Castle	7	Armor of Guardsman + 1M zen	—	Bless/Soul jewels; classic 1st-place set-option drop
Illusion Temple	6	Scroll of Blood +6 + Old Scroll +6 (lvl 96+)	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.
