The Illusion Knight of MU Online is Season 18's class: a one-handed-sword fighter whose entire kit gates on Agility — 80% of the official build, the most lopsided ratio in the game. This guide covers him end to end: the skills read from the game's own files, the tree, the blade ladder, cloaks from our server's item table, and how he plays on a live server.

Who the Illusion Knight is
Zakard was made — not born. Created as Kundun's avatar and then discarded, he turned the weapon's skills against their maker. In game terms he is an Agility-oriented swordsman: one-handed blades, attack-speed scaling, and a kit where four of the five core skills gate on Agility, not Strength. If you have played a Strength knight for years, this is the mirror version of that class.
He is a base class on current files — no unlock character, straight from the creation screen. His ladder runs Illusion Knight → Mirage Knight → Illusion Master → Mystic Knight → Phantom Pain Knight.
The skills, with the client's numbers
Read from the skill table our client and server run — level to learn, mana per cast:
| Skill | Level | Mana | What it does |
|---|---|---|---|
| Charge Slash | 25 | 80 | The opener and gap-closer — the kit's foundation |
| Wind Glaive | 45 | 150 | The mid-game strike that carries you to Blade Storm |
| Illusion Avatar | 100 | 200 | The signature: a phantom copy that fights beside him |
| Blade Storm | 160 | 300 | The clear — the skill the whole ladder builds toward |
| Oversting / Wild Breath | 300 | 320 | The late pair unlocked deep in the master levels |
The skill tree, from the client's own tree files
Every one of his core skills has an enhancement row in the client's tree data — unusually, the whole kit carries over:
| Tree row | Unlocks | Mana |
|---|---|---|
| Charge Slash Enhancement | 25 | 80 |
| Wind Glaive Enhancement | 45 | 150 |
| Illusion Avatar Enhancement | 100 | 200 |
| Blade Storm Enhancement | 160 | 300 |
| Oversting Enhancement | 300 | 320 |
| Wild Breath Enhancement | 300 | 320 |
And the Season 18 files ship the borrowed-behaviour line for the big one: Blade Storm of Fire — when it fires, the Charge Slash ability is implemented and range +1 applies. His tree is why the class feels complete: six enhancement rows means the kit you learned at 25 is still the kit at 1200.
How to build an Illusion Knight
The official ratio is the most lopsided in the game: 80% Agility / 15% Strength / 4% Stamina / 1% Energy. Agility is simultaneously his hit rate, his defence rate, his attack speed and his skill gate — one stat doing four jobs.
| Where you are | What to feed | Why |
|---|---|---|
| Always first | Agility | Four of five skills gate on it, and so does the blade ladder |
| Second | Strength | Meets the sword requirements the Agility pool doesn't |
| Almost never | Energy | 1% — his mana pool is small and stays small |
| Endgame, max stats 32,700 | Everything, in that order | On our server every stat caps at 32,700 and the tree takes over |
Gear: twelve blades of his own
His blade ladder runs Silver Blade (55) → Zeno (85) → Dragon (125) → Blood (150) → Archangel's Absolute (255) up through the socket and mastery tiers to the Manticore Blade — and below those, the shared one-handed pool (Short Sword, Kris, Blade, Double Blade) covers the first hour. Armour runs the same climb: socket sets from level 3, the four-piece versions holding the real bonuses, topped by Celestial Brilliant Illusion Knight at 1,300 — mastery skill attack power +16 and mastery Strength +25.
The cloak ladder, with server numbers
His back slot is a cloak ladder — levels and defence read straight from our server's item table:
| Cloak | Level | Defence | Notes |
|---|---|---|---|
| Iron Cloak | 150 | 20 | The starter cloak |
| Black Cloak | 215 | 45 | Shared with the Crusader |
| Cloak of Death | 290 | 27 | Shared with Dark Lord, Rage Fighter, Grow Lancer, Crusader |
| Cloak of Death | 400 | 60 | Exclusive — his third-class cloak, a different item with the same name |
| Cloak of Hatred | 800 | 170 | Exclusive — the fourth-class cloak |
| Cloak of Innocence | 1200 | 175 | Exclusive — the fifth-class cloak, the top of the ladder on current files |
The party trio
His official trio is Illusion Knight + Magic Gladiator + Fairy Elf. PvE he is a speed clearer: Charge Slash in, Blade Storm down, Avatar holding the second pack. PvP the Agility build's defence rate makes him frustrating to hit — he wins long fights, not bursts, and the Oversting/Wild Breath pair at 300 is what finally gives him a finisher.

The complete list, pulled straight from the skill table our server runs — level to learn, base damage, mana and AG cost, range, the stat gate, the +1-damage-per-X scaling and the imprint value. If another site disagrees with a number here, ours is the one the server actually uses.

The master skill tree (3rd class), node by node
Unlocked at the third class change (level 400); every level from 400 to 800 grants one point. Three branches, with the node names read from our server's own tree file:
Defense branch: Durability Reduction (1), PvP Defense Rate Increase, Maximum SD increase, Auto Mana Recovery Increase, Durability Reduction (2), SD Recovery Speed Increase, Automatic HP Recovery Increase, Defense Increase, Elemental DEF Increase, Automatic AG Recovery Increase, Durability Reduction (3), Defense Success Rate Increase, Armor Set Bonus Increase, Vengeance, Energy Increase, Stamina Increase, Agility Increase, Strength Increase, Reinforcement of Cloak of Death Defense, Stop Weapon, Reinforcement of Cloak of Death Attack, Steel Armor

What each stat point does
The classic MU formulas, with this class's damage stat in the first row. Per-point HP and mana are in the table at the top of the page.
| Stat | What each point gives |
|---|---|
| Agility (damage stat) | +1 max damage per 4 points (weapon line) |
| Agility (everyone) | +1 defense per 3 points, +1 defense rate per 4, +1 attack speed per 20 |
| AG (skill stamina) | +1 per 3 Agility, per 4 Vitality, per 5 Strength; +0.15 per Energy |
| SD (shield) | +1.2 per stat point and per level; +1 per 2 defense |
Class specialization and the EXP party
Two systems the stat screen never explains. First, specialization: as the class damage stat climbs past 1,500 and then 2,000, the character earns bonus damage on the same skill set — up to +45% at the top tier. Second, the classic EXP-party combos are Dark Knight + Dark Wizard + Fairy Elf and Dark Lord + Summoner + Magic Gladiator/Rage Fighter — this class belongs to neither, so build parties from the combat trios above.
Ability cards (5th class): Blade Storm of Saturation.
