Lost Tower Floors 3 and 4: Strong Monsters and Valuable Drops

Lost Tower Overview

The Lost Tower is one of the most iconic vertical dungeons in MU Online Season 6. With 7 floors of increasing difficulty (LT1 through LT7), it serves as the main progression route for characters moving out of the early game. Each floor presents more resilient monsters, better drops, and greater risks for those who are unprepared.

Floors 3 and 4 represent the inflection point between casual content and serious farming. Floor 3 already demands consistent equipment and understanding of monster behavior, while Floor 4 begins to compete directly with zones like Atlans and Tarkan in terms of drop quality.

Floor 3 Monsters

The third floor features three main monsters with distinct behaviors and specific dangers.

Devil Shaman

The Devil Shaman is the standard and most numerous mob on Floor 3. It has a magical attack with moderate range and occasionally applies a movement speed reduction debuff. Its ATK of 185–210 is manageable individually, but groups of 4 or more can catch characters with VIT below 200 off guard.

• Element: Darkness
• Behavior: active aggro at medium radius, follows the character for a considerable distance
• Main drops: Jewel of Soul, Jewel of Bless, level 52–60 equipment

Poison Shadow

The Poison Shadow is the most dangerous mob on Floor 3 for newer players. In addition to its direct physical damage of 200–230, it applies persistent poison dealing approximately 30–50 HP per tick every 2 seconds, lasting 10 seconds. When accidentally pulling multiple Poison Shadows simultaneously, the stacked effect can be lethal even at high HP totals.

• Element: Poison
• Behavior: fixed route patrol, medium aggro range
• Main drops: Jewel of Bless, level 52–60 armor pieces with magic options

Stone Golem

The Stone Golem is the patrol mini-boss of Floor 3. It spawns at fixed map positions with a respawn timer of approximately 10 minutes. Its HP of 5,500 and DEF of 140 make it resilient, requiring more time or burst damage to take down. The EXP reward is the highest on the floor, and its drops have a slightly higher chance of items with options.

• Element: Earth
• Behavior: slow patrol, melee knockback attack
• Main drops: Jewel of Life, Jewel of Bless, level 60–68 equipment

Notable Drops on Floor 3

Floor 4 Monsters

The fourth floor represents a considerable jump in difficulty. Monster stats rise significantly and the floor composition includes an elite with special mechanics.

Thunder Lich

The Thunder Lich is the main mob of Floor 4, an undead mage using ranged lightning attacks. Its attack covers a small splash area around the primary target, making pulls of multiple Thunder Liches particularly hazardous for medium-HP classes. The ATK of 240–275 represents roughly a 30% increase over Floor 3 mobs.

• Element: Lightning
• Behavior: stationary or slow-moving, ranged attack up to 6 tiles
• Main drops: Jewel of Bless, staffs and wands of level 60–72

Bloody Wolf

The Bloody Wolf is a melee mob with above-average attack speed. Its most dangerous trait is the rapid attack combo: in standard S6 configurations, it executes 2 attacks per animation cycle, effectively doubling perceived DPS compared to monsters with similar stats. Its HP of 5,800 with DEF of 145 requires builds with solid defense penetration or consistent damage per second.

• Element: Physical
• Behavior: aggressive aggro, high pursuit speed
• Main drops: Jewel of Soul, heavy armor pieces of level 60–72

Dark Knight (mob)

The Dark Knight mob is the elite of Floor 4 and should not be confused with the playable class. It has a knockback attack that pushes the character away, partial resistance to stun effects, and an attack pattern alternating between physical and magical damage. Its level 88 and HP of 7,200 make it one of the most resilient mobs outside of Kalima and Tarkan in this level range.

• Element: Mixed (Physical + Darkness)
• Behavior: fixed route patrol, knockback on the first hit of each attack sequence
• Main drops: Jewel of Bless, Jewel of Soul, level 64–76 items with magic options

Minimum Requirements by Class

To farm Floors 3 and 4 safely and efficiently in S6, the recommended base attributes are:

Strategies by Class

Dark Knight (Blade Knight)

The DK is the most efficient class on Floors 3 and 4 thanks to the combination of high VIT and area skills.

Floor 3 Rotation:
→ Twisting Slash on group of 4–6 mobs → reposition → repeat
→ Prioritize Poison Shadows first (eliminate before poison stacks)
→ Stone Golem: approach with full HP, use normal attack to conserve mana

Floor 4 Rotation:
→ Twisting Slash on Thunder Lich group → switch to normal attack on isolated Bloody Wolf
→ Dark Knight mob: individual combat with shield equipped to mitigate knockback

Target equipment:

• Weapon: Sword of Destruction +9 or Giant Sword +9 with ATK Speed option
• Armor: level 64–72 sets with HP increase option
• Shield: Dragon Shield with Excellent Defense Rate option

Dark Wizard (Soul Master)

The DW dominates Floor 4 with area skills and Soul Barrier as sustain.

Floor 3 Rotation:
→ Inferno on group → Evil Spirit on isolated target → repeat
→ Keep Soul Barrier active at all times (reduces incoming damage proportional to ENE)

Floor 4 Rotation:
→ Inferno for Thunder Lich groups (freezes and deals damage)
→ Lightning for burst damage on the Dark Knight mob
→ Recharge mana between pulls — Inferno mana cost is high

Elf (Muse Elf)

Solo DPS (Floor 3):
→ Triple Shot for mob groups — each shot generates 3 hits with critical chance
→ Infinity Arrow: activate the buff before each farm session (+ATK for its duration)
→ Never engage in melee with Stone Golem — maintain maximum distance

Support in Party (Floor 4):
→ Attack Buff (+% ATK based on ENE for all party members)
→ Defense Buff (+% DEF based on ENE for all party members)
→ Continuous Heal to neutralize residual poison effects and recover HP after pulls

Magic Gladiator (Duel Master)

The MG has no first or second quest and therefore lacks Level 1 Wings and intermediate quest bonuses. Compensate with balanced stats between STR, AGI, and ENE to maximize mixed damage output.

Floor 4 Rotation:
→ Teleport for rapid repositioning between groups
→ Alternate between physical attacks (STR) and magic (ENE) depending on the mob
→ Focus physical attacks on Bloody Wolf — lower DEF than Thunder Lich

Farming Strategies

Solo Farm — Sector Clear Method

Step by step:
→ Position your character in a corner of the map to limit aggro angles
→ Attract 3–5 mobs at a time (avoid more than 8 without strong AoE)
→ Floor 3: eliminate Poison Shadows first, then Devil Shamans, Stone Golem last
→ Floor 4: eliminate Thunder Liches first (splash damage), then Bloody Wolves
→ Dark Knight mob: always approach individually with HP above 70%
→ Return to the entry portal to use potions without risk of additional aggro
→ Mob respawn cycle: 5–10 minutes per group

Party Farm — Ideal Setup

Recommended composition (4 players):
→ 1x DK Tank (VIT 400+, holds central aggro)
→ 1x DW DPS (ENE 500+, Inferno + Lightning for rapid clearing)
→ 1x Elf Support (ATK/DEF buff + heal to sustain the tank)
→ 1x MG or DL as additional DPS

Positioning:
→ DK in the center of the mob group to concentrate aggro
→ DW and DL on the outer edges firing Inferno/AoE into the group
→ Elf behind the DK, out of mob range, buffing and healing

Access Route

Access to Floors 3 and 4:
Lorencia (125, 86) → Portal → Lost Tower 1
Lost Tower 1 → Internal Portal → Lost Tower 2
Lost Tower 2 → Internal Portal → Lost Tower 3
Lost Tower 3 → Internal Portal → Lost Tower 4

Conclusion

Lost Tower Floors 3 and 4 are essential in the intermediate progression of MU Online S6. Floor 3 offers accessible Jewel of Bless and Soul farming with manageable risks, while Floor 4 raises the drop standard — especially Jewel of Soul at ~3.5% — and begins requiring builds and equipment that will serve as the foundation for high-level zones like Tarkan, Aida, and Kanturu.

Mastering monster behavior — the persistent poison of the Poison Shadow on LT3, the Thunder Lich splash and Bloody Wolf speed on LT4 — is just as important as having the correct stats. With proper preparation, these two floors provide hours of productive farming and resources that significantly accelerate character development.
