The Dark Lord in MU Online S6

The Dark Lord (DL) is one of the six playable classes in MU Online Season 6. He stands out as the only class with the exclusive CMD (Charisma) stat, which governs his ability to lead Spirits — the Dark Horse and the Dark Raven. Upon completing the 3rd Quest, the DL evolves into Lord Emperor, unlocking enhanced skills and greater damage potential.

Nota: The Dark Lord has no 1st or 2nd Quest intermediate evolution steps, unlike DK, DW, and Elf. He goes directly from his base state to Lord Emperor at the 3rd Quest, upon reaching level 400 with all requirements met.

Dica: Each point in CMD increases the maximum number of Spirits the DL can have active simultaneously. PvP builds focused on party support invest heavily in CMD to keep both Dark Horse and Dark Raven active with maximum efficiency.

Dark Lord Skills

Fireburst

Type: Magic area damage (AoE) Level Requirement: 0 (available from the start) ENE Requirement: 20

Fireburst is the DL's starting skill. He conjures a burst of flames around himself, hitting multiple enemies in a short range. It is the primary farming skill at early levels.

Approximate damage formula:

Damage = (ENE / 8) + (Skill Level × 3) + Weapon Min Damage
Skill LevelDamage BonusMana Cost
1+030
5+3035
10+7040
15+12045
20+18050

Electric Whip

Type: Long-range magic damage Level Requirement: 140 ENE Requirement: 150

Electric Whip is one of the most iconic DL skills. The character launches an electric energy whip that travels in a straight line, dealing damage to all enemies in its path.

Approximate damage formula:

Damage = (ENE / 6) + (CMD / 10) + (Skill Level × 5) + Weapon Min Damage
Dica: Electric Whip is one of the few skills that scales with CMD in addition to ENE, making hybrid builds with high Charisma even more relevant in terms of damage output.
Skill LevelDamage BonusRange
1+06 tiles
5+506 tiles
10+1107 tiles
15+1807 tiles
20+2608 tiles

Chaotic Diseier

Type: Single-target magic projectile Level Requirement: 220 ENE Requirement: 200

The DL's highest single-target damage skill. Launches a chaotic energy projectile that deals massive damage to a single target. This is the primary PvP and boss-killing skill for the DL.

Approximate damage formula:

Damage = (ENE / 5) + (CMD / 8) + (Skill Level × 7) + Weapon Damage × 1.5
Atenção: Chaotic Diseier consumes a large amount of Mana. Make sure you have enough potions or a support Elf in your party when using this skill continuously against bosses such as Kundun or Selupan.

Dark Horse (Dark Horse Summon)

Type: Summon / Passive buff Level Requirement: 0 (requires Dark Horse item equipped) Minimum CMD Requirement: 30

The Dark Horse is a Spirit exclusive to the Dark Lord. When mounted, the DL gains bonuses to movement speed, attack, and defense. The Dark Horse's upgrade level (max. +15) directly affects the bonuses granted.

Dark Horse bonuses by level:

Dark Horse LevelSpeed BonusAdditional DamageAdditional Defense
+0+10%+50+30
+5+15%+120+70
+10+20%+210+130
+15+25%+320+200
Nota: The Dark Horse can be upgraded with Jewel of Bless, Jewel of Soul, and Jewel of Life, just like regular equipment. A Dark Horse +11 or higher requires Jewel of Life to maintain the level on a failed upgrade attempt.

Dark Raven (Dark Raven Summon)

Type: Summon / Auto-attack Level Requirement: 0 (requires Dark Raven item equipped) Minimum CMD Requirement: 50

The Dark Raven is the DL's second Spirit. When summoned, it automatically attacks enemies near the DL's target. CMD determines how many attacks per second the Raven can execute and its base damage.

Dark Raven damage by level:

Dark Raven LevelMin DamageMax DamageAttacks/s
+040801.0
+51001801.2
+101803001.5
+152804501.8
Dica: To control Dark Horse and Dark Raven simultaneously, the DL needs enough CMD to cover both Spirit costs. Check the CMD requirements on each Spirit item before attempting to summon both at once.

Summon (Ally Summon)

Type: Utility / Party teleport Level Requirement: 0 ENE Requirement: 30

Summon is the DL's most useful support skill in a party context. It allows the Dark Lord to call a party member to his current location, making it easy to regroup during events such as Blood Castle, Devil Square, and Castle Siege.

Steps to use Summon:
1. Open the party menu
2. Select the member to summon
3. Activate the Summon skill
4. The member receives a confirmation window
5. Upon accepting, they are teleported to the DL's position
Nota: Summon has a cooldown of approximately 5 seconds between uses. The summoned member must accept the invitation — they are not teleported automatically.

Improvement (Party Attribute Buff)

Type: Party support buff Level Requirement: 0 CMD Requirement: 50

Improvement is a passive/active buff that the Dark Lord applies to party members. While the DL is in the party, all members receive bonuses to STR, AGI, and defense proportional to the DL's CMD stat.

Improvement bonuses by CMD:

DL's CMDSTR BonusAGI BonusDefense Bonus
100+10+10+15
200+22+22+32
300+35+35+50
400+50+50+70
500+65+65+92
Dica: The Dark Lord is one of the most valuable party supports for Castle Siege and events precisely because of Improvement. A DL with 400+ CMD can significantly increase the entire team's DPS and survivability.

Lord Emperor Exclusive Skills

After completing the 3rd Quest and evolving into Lord Emperor, the character unlocks enhanced versions of existing skills and new powers.

Enhanced Electric Whip

The Lord Emperor's Electric Whip has a higher base range (fixed at 8 tiles) and deals 20% more damage than the Dark Lord version. In addition, the Stun effect now has a 15% chance to trigger instead of 8%.

Enhanced Chaotic Diseier

The Lord Emperor version of Chaotic Diseier ignores 15% of the target's defense, making it even more effective in PvP and against high-defense bosses such as Selupan (Raklion) and Balgass (Crywolf Fortress).

Atenção: The evolution to Lord Emperor is permanent and irreversible. Make sure you meet all requirements (level 400, quest completed) before performing the evolution.

Evolution Path

Lord Emperor (Level 400+)
Nota: Unlike DK (Blade Knight → Blade Master), DW (Soul Master → Grand Master), and Elf (Muse Elf → High Elf), the Dark Lord has no intermediate evolution steps from 1st or 2nd Quests. He goes directly from base state to Lord Emperor.

Dica: The high-CMD support build is especially effective on servers focused on Castle Siege, where the DL's Improvement buff can decide battles. For servers more oriented toward PvM, balance ENE and CMD to maximize Electric Whip damage.
