MU Online Illusion Knight – Skills, Blades, Stats & Guide

The Illusion Knight arrived in Season 18 and fights with a phantom blade summoned into his empty left hand. He is an Agility-based melee class — unusual in that Agility drives both his attack and his skill power — with some of the fastest area clear in the game. Every number on this page comes straight from the Season 21 server files, and every render from the game client.

How the Illusion Knight 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

Born as a fragment of Kundun, Jacquard outclassed his peers with the sword effortlessly — yet as a descendant of the Magic Gladiator line who could wield neither magic nor a magic sword, he was never accepted, and hid his lineage for years. Then, blocking an incoming blade in a sparring match, a phantom of his sword appeared in his empty left hand. He trained the illusion relentlessly, learned to phantomise his weapon and even himself, won Kundun’s trust and became famous across MU — until a mission at Lost Tower left him fighting the horde alone, abandoned. Wounded and betrayed, he cut his way out, defeated Balrog, and walked out to carve his own path, bent on revenge against Kundun. Even the game files remember him: the client stores every Illusion Knight model under his name, jacquard.

Stats & Class Line

The Phantom Blade — the Class Mechanic

Two skills define the class, and the server’s own buff descriptions explain them better than any wiki:

Two hard limits from the server files: the Avatar cannot be used with offline levelling (the server refuses it with a dedicated message), and it unsummons if you outrange it. It deals no PvP damage and is banned in Chaos Castle.

All Illusion Knight Skills

The class kit is deliberately short — five signature skills plus two generic melee openers, every one of them scaling from Agility:

On top of these come the shared utility every melee class carries: Stun, Swell Mana, Invisibility, the Crywolf spell set, and Blessing of Experience at level 50.

The rotation writes itself: keep Illusion Blade up, keep the Avatar out, and spam the biggest AoE you have unlocked — Charge Slash until 45, Wind Glaive until 160, Blade Storm after. With 3–10 mana costs the class effectively never drinks mana potions while farming, which is why it clears low-mana maps like Swamp of Calmness faster than almost anyone.

Master Skill Tree — 58 Nodes

The tree is compact and almost nothing in it is filler. Three branches matter:

Illusion Knight 4th Master Skill Tree (Season 20+)

The Season 20 4th skill tree replaced the old passive master tree with skill-specific branches. The Illusion Knight gets 3 branches holding 3 Enhancement Skills — Charge Slash Mastery, Wind Glaive Mastery, Blade Storm Mastery — 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 4 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 – Charge Slash Mastery

Branch 2 – Wind Glaive Mastery

Branch 3 – Blade Storm Mastery

Group 4 – finishing skills

The Blade Ladder — Every Weapon Rendered

The Blade is the Illusion Knight’s own weapon class — no other character can lift one. Four pre-400 blades, then the ten-step mastery ladder, then the two legendary blades:

Before level 400

The mastery ladder (400 → 1,500)

Legendary

Every blade’s requirements at a glance

Notice the plateau: from Silver Heart (1,100) onward the requirements freeze at STR 382 / AGI 1,216 — past that point every stat you add is pure damage, not gate-keeping.

Skill Beads — How the Skills Are Learned

The signature skills are taught by beads, the Illusion Knight’s version of orbs and scrolls. Three exist, all class-exclusive:

Illusion Avatar and Blade Storm come later through drops and the master tree path — Blade Storm needs Wind Glaive Mastery invested before it can be used at all.

Levelling Path by AGI Gate

Because skills and blades gate on Agility, the levelling route maps cleanly onto the AGI milestones:

Early Sets (Before Level 400)

Four sets carry a fresh Illusion Knight to the third class quest:

Then the two level 380–400 sets bridge into the mastery ladder:

The Set Ladder, Worn

The full mastery ladder from 400 to 1,500, then the two legendary sets — every one rendered on the character from the client models:

The biggest single jump is still the classic one: Lightning → Temple Guard at 1,500 takes the set from 2,268 to 2,617 base defense while the legendary blade arrives in the same bracket — weapon and armour spike together.

Set defense and requirements

Set Party Bonus

MU’s class-combination party bonus gives the Illusion Knight one defined combo: Illusion Knight + Magic Gladiator + Elf — a nod to the story, putting Jacquard back beside the bloodline that rejected him. Run it when you can: the Elf buffs multiply exactly the stats his Agility scaling feeds on.

Illusion Knight Ancient Sets

Every ancient set the Illusion Knight 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.

Cloaks — the Illusion Knight’s Wings

Like the Grow Lancer, the Illusion Knight wears cloaks instead of wings, and his master tree’s reinforcement pair targets the Cloak of Death:

He can also equip the shared utility wings — Wings of Growth, Wings of Conqueror, Wings of Angel and Devil, and the level-750 Wings of Power.

How to Play the Illusion Knight

Illusion Knight FAQ

Is the Illusion Knight good for new players?

Yes - arguably the easiest melee start in the game. His damage skills cost 3-10 mana, his main stat (Agility) raises attack, defense and skill power at once, and the Illusion Avatar effectively doubles your damage while farming.

What stat should an Illusion Knight focus on?

Agility. It gates every skill (80 / 650 / 900 / 1,150) and every blade (up to 1,216 for Silver Heart and above), and it is also his damage stat. Add only the STR each item demands - the highest STR gate in his whole kit is 487 on the Apex set.

What weapon does the Illusion Knight use?

The Blade - a weapon class only he can equip, running from the Silver Blade to the Lightning Blade at level 1,500, plus the legendary Temple Guard and Imperial Blades. The Illusion Blade buff copies whichever blade he holds into his left hand as a phantom.

Does the Illusion Avatar work in PvP?

No. The server files disable its damage against players, and it cannot be used in Chaos Castle or with offline levelling. In PvE it is a second copy of you that attacks nearby monsters.

What are the Illusion Knight cloak options?

Iron Cloak (150), Black Cloak (215), Cloak of Death (400), Cloak of Hatred (800) and Cloak of Innocence (1,200). His master tree carries two reinforcement nodes for the Cloak of Death, adding defense and attack on top of the cloak itself.

When does the Illusion Knight get strong?

Immediately at 25 with Charge Slash, again at 100 with the Avatar, and the endgame spike is level 1,500, where the Lightning Blade and the Temple Guard set arrive in the same bracket.
