MU Online Summoner – Skills, Builds, Stats & Guide

The Summoner is MU Online's curse caster — a class with two entirely different modes you swap between with a buff. Season 14 split her into the Sorceress (wizardry) and Curse Master (curse power) builds.

How the Summoner Looks at Every Evolution

The base character model at each class change, rendered from the game client’s own player files — no armour equipped, so you can see exactly what the evolution itself changes.

Story

Summoner	The Summoner draws on curses and bound spirits rather than raw elemental force. She carries a Stick and a Book, and her power comes from debuffing what she fights as much as from damaging it. Season 14 rebuilt her around a choice: activate Berserker to become a fast wizardry attacker, or Darkness to unlock her curse skills and area damage. Each disables the other.

Stats & Class Line

All Summoner Skills – Level, Cost, Range & Role

Pulled directly from the server skill table (Season 21 files), in unlock order: every skill the Summoner line can learn from creation to 5th class, and what it is for. Lv is the character level, Req the stat gate, AG the ability-gauge cost, Range in tiles, CD cooldown (buff duration in brackets). Shared utility (Stun, Swell Mana, Invisibility, the Crywolf spells) and master-tree skills are not repeated here.

Energy is the gate on every one of these — Lightning Shock alone needs 823 Energy. Plan stat points around the next skill you want, not around the one you have.

Summoner Master Skill Tree

At 3rd class you unlock the master skill tree and start earning master points. The Summoner tree has 66 nodes. Numbers in brackets are the maximum points per node.

See the master skill tree guide for how points are earned and which nodes to take first.

Summoner 4th Master Skill Tree (Season 20+)

The Season 20 4th skill tree replaced the old passive master tree with skill-specific branches. The Summoner gets 4 branches holding 4 Enhancement Skills — Death Scythe, Lightning Shock Strengthener, Aqua Beast, Fire Beast — each built around an Enhancement Skill (a boosted version of the base skill) with link nodes that modify it, a debuff proc (a magic circle that spawns on hit) and passives that upgrade the debuff. Group 5 holds the shared finishing skills Poison Storm, Frozen Slayer, Bloodying Hit. Points come from master levels; every node lists its cap and what it needs unlocked first. Text is the client tooltip with the per-point value shown as N.

Branch 1 – Death Scythe

Branch 2 – Lightning Shock Strengthener

Branch 3 – Aqua Beast

Branch 4 – Fire Beast

Group 5 – finishing skills

Curses vs Damage – What Makes the Summoner Different

The Summoner is the only class in MU Online built around curses: debuffs that weaken enemies rather than raw damage. That is why she is prized in parties and feared in Castle Siege, and it is why her two stances are exclusive:

They cancel each other, so pick a stance per situation rather than trying to run both. The master tree reinforces this split — Berserker Strengthener/Proficiency on one side, Darkness Strengthener/Mastery on the other.

Gear

She wields a Stick in the main hand and a Book in the off hand:

Mastery & Legendary weapon ladder

The full upgrade chain, straight from the game files. Each step needs the previous weapon at +11 with +16 option plus the listed material, combined at the Chaos Machine. Every upgrade is 100% success — the only gamble is making the Ancient Hero's Soul at the start.

Weapon	Char. Lv	Damage	Requirements	Upgrade material
Bloodangel Stick	400	81–87	STR 257 / AGI 88	Sealed set from Priest James + Ancient Hero's Soul
Darkangel Stick	600	111–117	STR 269 / AGI 93	Darkangel Anvil
Holyangel Stick	800	127–135	STR 273 / AGI 94	Holyangel Anvil
Blue Eye Stick	1000	164–172	STR 284 / AGI 97	Blue Eye Anvil
Silver Heart Stick	1100	183–194	STR 288 / AGI 101	Silver Heart Anvil
Manticore Stick	1200	202–216	STR 288 / AGI 101	Manticore Anvil
Brilliant Stick	1300	221–238	STR 288 / AGI 101	Brilliant Anvil
Apocalypse Stick	1400	240–260	STR 288 / AGI 101	Apocalypse Anvil
Lightning Stick	1500	259–282	STR 288 / AGI 101	Lightning Anvil
Temple Guard Stick	1500	278–304	STR 283 / AGI 96	Temple Guard Anvil (1st Legendary)
Imperial Stick	1600	327–353	STR 283 / AGI 96	Imperial materials (2nd Legendary)

Temple Guard and Imperial are not mastery tiers — they are 1st and 2nd Legendary, a separate system above the 10-tier mastery ladder.

Early Sets – What to Wear Before Level 400

Every set further down this page needs level 400+. These are the ones you actually wear on the way there, in the order you will find them. Drop level is roughly the monster level where the pieces start appearing:

The early curve is gentle — Violent Wind to Ancient roughly doubles your defense across the first 60-odd levels. The real jumps come at Storm Blitz and Eternal Wing (both level 380), and then Succubus at 400, which is the last classic set before the mastery ladder opens with Bloodangel.

Summoner Set Ladder – Every Tier Worn

This is the Summoner’s full gear progression, each set composited onto the character from the game client’s own model files — so you can see what you will actually look like, not just inventory icons. Twelve tiers, from your first mastery set at level 400 to the Imperial end-game at 1,600.

Defense climbs steadily — roughly 225 per tier through the mastery ladder — then jumps at the Legendary tiers. Every set from Bloodangel upward is Summoner-exclusive: her sets use their own models rather than recolours shared with other classes, which is why the visual identity changes so much between tiers.

Summoner Ancient Sets

Every ancient set the Summoner can wear, read from the server’s set files. Ancient items look exactly like their base set (an ancient Dragon Helm is still a Dragon Helm), so each card shows the base armour worn. Options unlock one at a time as you equip more pieces of the same set; the full-set bonus needs every piece, including any weapon, shield, ring or pendant that belongs to it.

Ancient items also carry a hidden stat bonus by tier (Tier I +5, Tier II +10 to the set’s stat) and can only be obtained from the Illusion Temple, Blood Castle, Chaos Castle and boss drops.

Summoner Wings

The Summoner’s wing line, rendered from the game client. Wings are the single biggest power jump available to her — see the full wings guide for combination recipes and success rates.

Models rendered from the MU Online game client by MuOnline.Net. The master skill tree nodes Dimension Wings Attack PowUp and Dimension Wings Defense PowUp (20 points each) scale directly with the 3rd-tier wings.

Imperial Set – the Summoner End-Game

The Imperial set is the Summoner’s current ceiling: 2nd Legendary grade, level 1,600 required, and a dedicated Summoner model line rather than a shared recolour. Rendered here from the game client:

The matching weapons are the Imperial Stick (327–353 damage, 532 magic power, STR 283 / AGI 96) and the Imperial Scripture off-hand (515 curse power, AGI 202 / ENE 876 — note the huge Energy requirement, which is why Energy stays your main stat right to the end).

FAQ

Is the Summoner good in MU Online?
Yes — she has strong area damage and unique debuff tools. The Curse Master build with Death Scythe is a very effective farmer, while the Sorceress build offers fast wizardry damage.

What is the difference between Berserker and Darkness?
Berserker makes you a Sorceress — raising wizardry and attack speed at the cost of HP and defense, but disabling your curse skills. Darkness makes you a Curse Master — raising curse power and defense and enabling curse skills. You cannot use both.

What stats does the Summoner use?
Energy is the main stat for both builds, since both buffs and all damage scale from it. Add Vitality to offset the HP cost of the buffs.

What is Death Scythe?
The Curse Master's signature skill (Pollution Mastery 10P, Dark element). It creates a scythe that follows you and attacks in a 6-tile radius hitting up to 6 targets, vanishing after 10 seconds without use.
