All Summoner / Dimension Master Skills in MU Online
Complete guide to all Summoner and Dimension Master skills in MU Online S6: damage formulas, requirements, stats, and strategy tips.
Summoner Class Overview
The Summoner is the only exclusively female class in MU Online S6, specializing in chaotic magic and creature summons. Unlike other classes that rely on STR or VIT, the Summoner scales primarily through ENE (Energy), making every point invested in that attribute directly relevant to the damage of all her skills.
Her evolution path is:
Summoner → Bloody Summoner (1st Change-Up Quest) → Dimension Master (2nd Change-Up Quest)Nota: The Summoner begins with access to a unique skill tree divided into two branches: Curse Skills and Summon Skills. The most powerful abilities only become available after evolving to Dimension Master.
Base Stats and Attributes
| Attribute | Starting Value | Notes |
|---|---|---|
| STR | 22 | Free allocation |
| AGI | 19 | Free allocation |
| VIT | 19 | Free allocation |
| ENE | 25 | Primary stat — prioritize |
Base HP formula: VIT × 2 + Level × 1.5 + 80. Mana scales heavily with ENE: ENE × 2.5 + 100 (base).
Atenção: Over-investing in VIT compromises damage output significantly. Competitive PvM builds concentrate 80–90% of free stat points into ENE, relying on gear for HP compensation.
Summoner Skills (Base Form)
Summon Goblin
- Requirement: Level 0 / ENE 0
- Type: Summon
- Description: Summons a Goblin that automatically attacks nearby enemies. The Goblin's HP scales with the Summoner's ENE and persists until killed.
- Use: Starting summon for early leveling in Lorencia and Noria.
Summon Stone Golem
- Requirement: Level 40 / ENE 100
- Type: Summon
- Description: Summons a Stone Golem with higher HP and damage than the Goblin. Effective for farming in Devias and Dungeon 1F–2F.
- Golem HP Formula:
ENE × 3 + Level × 2
Summon Nightmare
- Requirement: Level 80 / ENE 200
- Type: Summon
- Description: Summons a Nightmare creature that applies debuffs to enemies in addition to dealing physical damage. The only summon with a crowd-control component.
Decay
- Requirement: Level 20 / ENE 60
- Type: Curse – Damage over Time (DoT)
- Description: Launches a poison curse that deals continuous damage for 5 seconds. Can be stacked on multiple targets simultaneously.
- Damage Formula (per tick):
ENE / 8 + Level / 5
Dica: Decay is extremely effective against high-HP bosses such as Red Dragon and Golden Dragon, since the per-tick damage scales well and requires no attention after casting.
Ice Storm
- Requirement: Level 50 / ENE 130
- Type: Magic – AoE (Area of Effect)
- Description: Launches a storm of ice crystals that strikes multiple enemies in an area and applies a Slow effect for 3 seconds.
- Damage Formula:
ENE × 0.85 + Level × 2.5 - Cooldown: 2 seconds
Chain Lightning
- Requirement: Level 75 / ENE 180
- Type: Magic – Multi-target
- Description: Fires a bolt of lightning that jumps between up to 5 nearby enemies, dealing decreasing damage with each jump (100% → 80% → 60% → 40% → 20%).
- Damage Formula (1st target):
ENE × 1.1 + Level × 3
Bloody Summoner Skills (1st Quest)
After completing the 1st Change-Up Quest (approximately level 150 with required items and missions), the Summoner evolves into Bloody Summoner and unlocks more powerful skills.
Summon Lacleon
- Requirement: Level 150 / ENE 350
- Type: Summon
- Description: Summons a Lacleon (dark creature) with significantly higher DPS than the Nightmare. Possesses a passive vampirism ability that drains 5% of damage dealt as HP.
Sahamutt
- Requirement: Level 160 / ENE 380
- Type: Summon
- Description: Summons the Sahamutt, a guardian with elevated defense. Functions as a tank in PvP situations or difficult dungeon encounters.
Neil
- Requirement: Level 170 / ENE 400
- Type: Summon
- Description: Summons Neil, the fastest of the Summoner's creatures. Possesses a 30% higher attack speed bonus compared to Lacleon.
Requiem
- Requirement: Level 164 / ENE 420
- Type: Curse – Debuff
- Description: Applies a curse that reduces the target's DEF by 20% for 8 seconds. Essential for party play in Castle Siege and Illusion Temple.
Nota: Requiem is one of the few defense-debuff skills available in the game. In groups, combining it with a DK Blade Knight or MG Duel Master maximizes collective DPS output significantly.
Pollution
- Requirement: Level 170 / ENE 450
- Type: Curse – Damage + Debuff
- Description: Wraps the target in chaotic energy, dealing immediate damage and reducing the target's attack speed by 15% for 6 seconds.
- Damage Formula:
ENE × 1.3 + Level × 4
Dimension Master Skills (2nd Quest)
Evolving to Dimension Master (2nd Change-Up Quest, approximately level 400) represents the pinnacle of the Summoner's power, granting access to the class's most devastating abilities.
| Skill | Level Req. | ENE Req. | Type | Primary Effect |
|---|---|---|---|---|
| Drain Life | 400 | 800 | Curse / Drain | Drains target's HP |
| Fire Scream | 420 | 870 | Magic AoE | Fire damage in an area |
| Dark Scream | 400 | 820 | Curse / Debuff | Reduces target ATK by 25% |
| Berserker | 430 | 900 | Self-Buff | +40% ATK, -20% DEF |
| Sleep | 410 | 850 | Curse / CC | Incapacitates target for 4s |
| Weakness | 415 | 860 | Curse / Debuff | Reduces target ENE by 30% |
| Innovation | 440 | 950 | Self-Buff | +20% attack speed |
Drain Life
- Requirement: Level 400 / ENE 800
- Type: Curse – Life Steal
- Description: Drains HP from the target and transfers it to the Summoner. The amount drained equals 15% of the target's maximum HP per second for 3 seconds (max. 45% total drain).
- Drain Formula:
ENE × 0.4 + 15% target_MaxHP
Atenção: Drain Life does not work effectively against bosses with curse resistance. Kundun and Selupan possess 70% curse resistance, drastically reducing its effectiveness. In PvP, the effect is reduced by 50% for balance purposes.
Fire Scream
- Requirement: Level 420 / ENE 870
- Type: Magic – AoE
- Description: Conjures a fire scream that radiates outward from the Summoner, striking all enemies within a 3-cell radius. This is the class's highest AoE damage potential skill.
- Damage Formula:
ENE × 1.8 + Level × 5 - Cooldown: 3 seconds
Dark Scream
- Requirement: Level 400 / ENE 820
- Type: Curse – Debuff
- Description: Reduces the target's ATK by 25% for 10 seconds. In PvP, it is one of the most impactful offensive debuffs available to any class.
Berserker
- Requirement: Level 430 / ENE 900
- Type: Self-Buff
- Description: Enters a state of chaotic fury: increases ATK by 40% while reducing DEF by 20% for 15 seconds. Ideal for quick burst damage windows.
Dica: Combine Berserker + Fire Scream + Chain Lightning for devastating burst against monster clusters. In Acheron and Vulcanus, this combo is especially efficient for high-level farming rotations.
Sleep
- Requirement: Level 410 / ENE 850
- Type: Curse – Crowd Control (CC)
- Description: Incapacitates the target for up to 4 seconds. The target is freed upon receiving any damage. Critical in PvP and Castle Siege for neutralizing priority targets.
Weakness
- Requirement: Level 415 / ENE 860
- Type: Curse – Magic Debuff
- Description: Reduces the target's ENE by 30% for 8 seconds, directly diminishing the magic damage output of other Summoners, Soul Masters, and Grand Masters.

|---|---|---|
| Gaia Set | Dark Soul | +ENE, +Critical Rate, +Curse Damage +15% |
| Broy Set | Venom Mist | +ENE, +Attack Speed, +Poison Damage +20% |
Nota: The Gaia Set (Dark Soul) is preferred for curse-focused PvM builds, while the Broy Set (Venom Mist) favors hybrid builds combining Decay and poison skills for PvP play.

Recommended Skill Rotations
PvM (Grinding in Acheron / Vulcanus):
Berserker (buff) → Fire Scream (AoE) → Chain Lightning (clean-up) → Decay (bosses)PvP (1v1 in Castle Siege):
Sleep (CC) → Dark Scream (debuff ATK) → Drain Life → Fire Scream → Chain LightningGroup Support (Illusion Temple / Imperial Guardian):
Requiem (DEF debuff) → Weakness (ENE debuff) → Pollution (slow) → Ice Storm (AoE)Dica: In events like the Imperial Guardian, the Dimension Master is one of the most versatile classes available: she can deal damage through Berserker, provide support through Requiem and Weakness, and apply AoE pressure with Fire Scream — all within a single build.
