Summoner: complete class guide for MU Online Season 6

The Summoner is MU Online's most distinctive class — a dark caster who fights through curses, poison, and draining magic rather than explosive spells. She requires more patience to master than DW or DK, but rewards skilled players with devastating PvP control and excellent sustained PvM farming.

Class overview

Class identity:

The Summoner's role:
→ DoT (damage over time) caster: skills drain HP continuously
→ Debuffer: applies curses that reduce enemy effectiveness
→ Sustained damage: not burst like DW — kills over 5-10 seconds, not 1
→ Control: Pollution (Poison) + Drain Life + slow/curse effects

Evolution path:
→ Summoner (level 1): basic skills, first summon abilities
→ Bloody Summoner (level 220, after 2nd class quest): enhanced skills
→ Dimension Master (Master Level + level 400): maximum skill access

Why Summoner is unique vs other casters:
→ DW (Grand Master): burst AoE (Nova kills instantly)
→ Summoner: DoT AoE (skills drain HP per second for duration)
→ DW: kills faster but more cast-dependent
→ Summoner: kills slower but sustains across multiple targets simultaneously
→ In PvP: Summoner's DoT can kill opponents who have already potted

Stat point allocation:

Energy (ENE) — primary stat:
→ Scales: all Summoner skill damage (Drain Life, Explosion, etc.)
→ ALL damage is ENE-based — this is the most important stat
→ Investment: 75-80% of free points into ENE

Vitality (VIT) — secondary:
→ HP pool: Summoner has very low base HP
→ Without VIT: dies to 2-3 hits in PvP
→ Investment: 15-20% of free points into VIT

Agility (AGI) — tertiary:
→ Defense: modest defense improvement
→ Attack rate: needed to land skills
→ Investment: 5-10% or minimum required for gear

Strength (STR) — minimum only:
→ Just enough to equip your staff
→ Don't invest beyond item requirement

Skills — complete breakdown

Core offensive skills:

Drain Life:
→ Type: AoE (area), DoT (damage per second for duration)
→ Mechanic: drains HP from all enemies in radius for several seconds
→ Range: medium AoE around Summoner
→ ENE scaling: very high — ENE directly determines drain rate
→ PvM use: cast in center of monster group → all drain simultaneously
→ PvP use: cast on enemy and wait — they need to pot heavily to survive
→ Weakness: channeling-adjacent — you must recast periodically to maintain
→ The Summoner's signature skill

Sahamutt (Summon):
→ Type: summon a creature to fight alongside the Summoner
→ Sahamutt deals independent damage to nearby enemies
→ Level scales with character level/ENE
→ PvM: helps with sustained DPS
→ PvP: serves as a "extra body" that enemies must also deal with
→ Note: unlike DL's pets, Summoner's summons are temporary spell-based

Pollution (Poison/Curse):
→ Type: debuff/DoT
→ Effect: applies poison DoT + reduces enemy stats/defenses
→ ENE scaling: poison damage scales
→ PvP use: apply at fight start → enemy loses HP throughout the fight
→ Combo: Pollution → Drain Life → enemy is both poisoned and drained

Explosion:
→ Type: burst AoE (instant damage, unlike Drain Life)
→ Summoner's closest equivalent to a "burst" skill
→ ENE scaling: high
→ PvM use: mixed with Drain Life for hybrid sustained + burst
→ PvP: opening burst before DoTs take effect

Requiem:
→ Type: area curse/debuff
→ Effect: reduces defense rate, move speed, or other stats (depends on server)
→ Makes enemies easier to hit with follow-up skills
→ Best use: open PvP with Requiem → enemy is debuffed → Drain Life lands harder

Decay:
→ Type: debuff (reduces enemy damage or reduces their stats)
→ Weakens enemies further while the Summoner's DoTs work
→ Important in PvP for reducing enemy burst against you

Skill priority for leveling:

Level 1-100: Focus on Drain Life primarily
→ Drain Life in monster group → sustained AoE damage → efficient farming
→ Don't spread points too thin at low level

Level 100-220: Add Explosion for burst assist
→ Drain Life + Explosion combo → clear groups faster

Level 220+ (Bloody Summoner): Add Pollution and curses
→ Full DoT + debuff kit now available
→ This is when Summoner becomes formidable in PvP

Level 400 (Dimension Master): Master Level trees
→ Enhance Drain Life damage and radius
→ Enhance Sahamutt summon stats
→ Enhance Explosion for burst

Build paths

Build 1: ENE-focused (recommended for most players)

Point allocation:
→ ENE: ~75% of free points
→ VIT: ~20%
→ AGI: ~5% (minimum for defense)

Result:
→ Maximum Drain Life damage
→ Sahamutt deals more damage
→ Explosion hits harder
→ Fragile in melee (relies on range)

Best for: PvM farming, PvP at range

---

Build 2: ENE/VIT balanced (more survivable)

Point allocation:
→ ENE: ~60%
→ VIT: ~35%
→ AGI: ~5%

Result:
→ Slightly lower damage
→ Significantly better survival vs burst PvP
→ Better in Castle Siege (harder to one-shot)

Best for: PvP-heavy servers, Castle Siege participation

---

Build 3: AGI hybrid (rarely used)

Point allocation:
→ AGI: ~40%
→ ENE: ~40%
→ VIT: ~20%

Result:
→ Better defense rate (harder to hit the Summoner)
→ Lower damage than pure ENE
→ More defensive profile

Best for: Very specific PvP builds, rarely optimal

PvP strategy

Summoner vs each class:

vs Dark Wizard (Grand Master):
→ DW threat: Nova burst (instant damage)
→ Summoner strategy: stay at range outside Nova radius
→ Apply Drain Life + Pollution before DW can position for Nova
→ Win condition: DoT drains DW before they land Nova
→ Note: if DW lands Nova first → Summoner likely dies

vs Dark Knight (Blade Master):
→ DK threat: Twisting Slash + Death Stab combo
→ Summoner strategy: kite — Drain Life while moving away
→ Pollution applied → DK is poisoned while chasing
→ Use Requiem → reduces DK defense rate → easier to drain
→ Win condition: Summoner must not let DK reach melee range

vs Fairy Elf:
→ If Elf is buffing → attack the buff source (Elf)
→ Drain Life on Elf at range → Elf has low HP
→ PvP vs AGI Elf: they kite back → you Drain Life → they run while taking DoT
→ Elf has better range → challenging matchup for Summoner

vs Magic Gladiator:
→ MG's threat: Frost Nova freeze → Twisting Slash
→ If MG gets Frost Nova on Summoner → likely dead
→ Strategy: apply DoTs at range, never let MG close
→ Pollution + Drain Life at range → manageable if MG can't close

vs Dark Lord:
→ DL mounted → Fire Scream is amplified → dangerous burst
→ Summoner strategy: Decay on DL (reduces DL damage)
→ Stay beyond Fire Scream range → Drain Life from safe distance
→ DL's summon (teleport) is problematic → watch for sudden party appearance

vs Summoner mirror:
→ Both have DoT at range
→ Win condition: better ENE scaling + better positioning
→ Apply Pollution first → debuffed Summoner is easier to Drain
→ The Summoner with better ENE gear wins mirror matchups

Universal Summoner PvP rules:

1. NEVER let melee classes close the distance
→ Your only defense is range
→ Retreat continuously if chased

2. Apply DoTs in order:
→ Pollution (debuff + poison) FIRST
→ Requiem (defense reduction) SECOND
→ Drain Life THIRD (hits debuffed/poisoned enemy)
→ Order matters — debuffs amplify Drain Life damage

3. Use Sahamutt as distraction:
→ Sahamutt draws enemy focus briefly
→ While enemy targets Sahamutt: reapply Drain Life

4. Potions vs DoT:
→ Opponents will pot constantly against your DoTs
→ Your goal: drain faster than they can pot
→ Higher ENE → drain rate exceeds potion rate

PvM farming efficiency

Summoner vs other classes for farming:

Summoner strengths:
→ Drain Life damages ALL monsters in AoE simultaneously
→ DoT is maintained for several seconds → walk to next group, previous group still draining
→ Mana efficient: fewer recasts than DW Nova (Nova needs constant recasting)

Summoner weaknesses:
→ Kill speed slower than Grand Master Nova
→ Need higher ENE investment for comparable damage
→ Requires Ancient ENE set to compete with DW/DK at same gear tier

Practical comparison at level 300:

Grand Master DW (full Wind set):
→ Nova: instant kill of 10-15 monsters
→ Time per Nova: 3 seconds to cast → 15 monsters dead
→ Fastest farming of any class

Dimension Master Summoner (full Valiant set):
→ Drain Life: 8-12 monsters take DoT
→ While they drain: walk to next group → previous group dies
→ More "ambient" clearing style
→ Slightly slower per minute but more mana efficient

Verdict: DW faster for burst clearing; Summoner better for sustained/marathon sessions

Best maps for Summoner farming:

Early-mid (level 100-250):
→ Atlans 3 (Silver Valkyrie): Drain Life in dense Valkyrie groups
→ Tarkan 1 (Iron Knight): slower than DK/DW here but viable

Late game (level 250-400):
→ Aida: Bloody Queen spawn — excellent for Summoner DoT (monsters cluster)
→ Kanturu 2: high-density for Drain Life AoE
→ Raklion: end-game farm with proper gear

Gear priorities

Weapons (staff):

Key attribute: ENE bonus on weapon
→ Ancient staff with ENE increase option: priority
→ Excellent staff with max ENE% option: alternative

Armor sets:

Best: Valiant Ancient Set (5 pieces):
→ ENE bonus + Mana increase from set bonus
→ Full set = maximum spell damage
→ The canonical Summoner set

Alternative: Seraphim Ancient Set:
→ ENE + DEF bonus
→ Better survivability
→ Used on PvP-heavy servers

Wings: Wings of Despair (Wing L1, Summoner-specific)
→ Required for Wing L2 (Despair + Loch's Feather + JoChaos)

Pet: Dinorant (flight + knockback immunity)
→ Flight: can access elevated areas
→ Knockback immunity: critical in Castle Siege (knockback would disrupt DoT casting)

---

Summoner gearing checklist:

Priority 1: ENE scaling gear (staff + Ancient set)
Priority 2: Mana capacity (more Drain Life casts)
Priority 3: HP (VIT investment + Ancient HP bonus)
Priority 4: Wings (Wing L2 → Wing L3 for maximum stats)
