Lost Tower Farm Guide: All 7 Floors Explained

Lost Tower is one of the most versatile maps in MU Online S6, with seven progressive floors that serve characters from early development all the way to veterans hunting Jewels and high-level equipment. This guide covers each floor with precision — monsters, approximate coordinates of the best spots, drops, and the ideal build to maximize your yield.

Why Farm in Lost Tower?

Lost Tower occupies a unique position in the game's progression: it is harder than Dungeon and Atlans, but less demanding than Tarkan and Icarus. This makes it ideal for characters between level 150 and 350 who need:

• Progression Jewels: Soul, Life and Chaos appear on every floor
• Mid-to-high tier sets: Dark Phoenix Set, Dark Soul Set, Thunder Hawk Set
• Consistent experience: high monster density on all floors
• Build testing: great place to test stat allocations before tougher maps

Minimum Requirements per Floor

Before detailing each floor, check the recommended minimum profile:

Build for Farm in Lost Tower

Dark Knight — Blade Knight (PvM STR)

The Blade Knight is the most robust choice for solo farming in Lost Tower across intermediate and upper floors.

Stat allocation at level 300:

• STR: 500 points
• AGI: 200 points
• VIT: 200 points
• ENE: 0 points (minimum for equipment requirements)

Stat allocation at level 400:

• STR: 650 points
• AGI: 250 points
• VIT: 300 points
• ENE: 0 points

Use Twisting Slash as your primary skill — it hits multiple enemies in an area and is the most efficient for group clearing. Keep a sword two tiers above your current level with a damage option of +28 or higher.

Dark Wizard — Soul Master (PvM ENE)

The Soul Master is devastating in dense groups thanks to Chain Lightning and Meteor.

Stat allocation at level 300:

• STR: 100 points (minimum to wear armor)
• AGI: 100 points
• VIT: 150 points
• ENE: 700 points (all remaining points)

Stat allocation at level 400:

• STR: 120 points
• AGI: 120 points
• VIT: 200 points
• ENE: 1,100 points

Fairy Elf — Muse Elf (Support or AGI Archer)

The Muse Elf works well as a party support, but is also viable as an AGI Archer for solo farming on floors 1-4.

AGI Archer Build — level 300:

• STR: 150 points (to equip bows)
• AGI: 700 points (main stat)
• VIT: 150 points
• ENE: 50 points

Floor 1 — Lost Tower 1 (LT1)

Recommended level: 150–200 Monsters: Skeleton Warrior, Skeleton Archer, Skeleton Lieutenant

Skeleton Warriors and Archers have low HP and decent drops of Zen and small Jewels. The most efficient spot on Floor 1 is in the central region of the map, where Skeleton Archers tend to cluster in higher density.

Notable drops from Floor 1:

• Jewel of Chaos (low rate)
• Level 4-5 weapons
• Moderate amounts of Zen

LT1 farm routine:
1. Enter Floor 1 through the portal in Lorencia
2. Go to the center of the map (coordinates ~120, 120)
3. Use Twisting Slash (DK) or Chain Lightning (DW) on groups of 5+ monsters
4. Do not use potions on Floor 1 if you are level 150+ with adequate equipment
5. Move up to LT2 when the Zen drop is below 5,000 per kill

Floor 2 — Lost Tower 2 (LT2)

Recommended level: 180–230 Monsters: Skeleton Warrior (enhanced version), Hell Spider, Poison Bull Fighter

The Hell Spider is the standout monster of Floor 2. They attack in groups and have a chance to poison, so characters with low status resistance can have trouble. The Poison Bull Fighter is more resilient and drops more Zen.

Notable drops from Floor 2:

• Jewel of Soul (regular rate)
• Jewel of Chaos
• Level 5-6 weapons
• Antidotes (an ironic drop from the poisoners)

Recommended spot: Northeast corner of the map, where Hell Spiders concentrate in the greatest density.

Floor 3 — Lost Tower 3 (LT3)

Recommended level: 210–260 Monsters: Hell Spider (elite variant), Poison Bull Fighter, Cursed Wizard

The Cursed Wizard is the first monster with significant magical attacks in Lost Tower. It uses spells that bypass part of physical defense, making Floor 3 a turning point for characters focused solely on physical defense.

Notable drops from Floor 3:

• Jewel of Soul
• Jewel of Life (starts appearing)
• Level 6-7 sets (Dark Phoenix Set pieces start here)
• Level 6-7 weapons

LT3 farm routine:
1. Prioritize eliminating Cursed Wizards first (they attack at range)
2. Group Poison Bull Fighters and clear with area skill
3. Make a circular route across the map to not let spawn accumulate
4. Switch floors every 30-40 minutes to take advantage of respawn

Floor 4 — Lost Tower 4 (LT4)

Recommended level: 240–290 Monsters: Cursed Wizard (elite), Death Knight (monster), Devil

The Death Knight (monster, not the class) is the most dangerous enemy up to this point. It has high physical defense, good HP, and attacks in melee with high damage. The Devil uses magical attacks and can be hard to hit for classes with low accuracy (low AGI).

Notable drops from Floor 4:

• Jewel of Life (improved rate)
• Jewel of Soul
• Dark Phoenix Set (higher chance)
• Dark Soul Set (parts start appearing)
• Level 7 weapons

Floor 5 — Lost Tower 5 (LT5)

Recommended level: 270–320 Monsters: Death Knight (elite variant), Balram, Soram

Balram is the standout monster of Floor 5. It has high HP, devastating physical attack, and above-average speed. Soram complements this with magical attacks. These two together make Floor 5 one of the most demanding floors in terms of survivability.

Notable drops from Floor 5:

• Jewel of Life (good rate)
• Jewel of Soul (good rate)
• Dark Phoenix Set (complete)
• Thunder Hawk Set (parts start here)
• Level 8 weapons

LT5 farm routine (DK level 300+):
1. Use Twisting Slash only when 4+ monsters are grouped together
2. Focus Sorams first (magical type, weaker to physical)
3. Have at least 500 large potions in your bag
4. Activate Bless + Soul on weapon and shield to maximize damage and defense

Floor 6 — Lost Tower 6 (LT6)

Recommended level: 300–340 Monsters: Balram (elite), Soram (elite), Dark Knight (powerful monster version)

Floor 6 is where farm returns skyrocket. Monsters here have the best drops of complete sets and Jewels in Lost Tower before Floor 7. Density is high and respawns are frequent.

Notable drops from Floor 6:

• Jewel of Life (high rate)
• Jewel of Soul (high rate)
• Jewel of Bless (appears rarely)
• Thunder Hawk Set (reasonable rate)
• Dark Phoenix Set (common)
• Level 8-9 weapons with options

Recommended spot: North-center of the map, where Balrams and Sorams spawn in large numbers close together.

Floor 7 — Lost Tower 7 (LT7) — The Final Floor

Recommended level: 330–400+ Monsters: Balram (max variant), Soram (max variant), Dark Knight (elite), Balgass (Boss)

Floor 7 is the pinnacle of Lost Tower. Balgass is the area boss that roams the map and attacks any player who crosses his path. He has extremely high HP, devastating damage both physical and magical, and is capable of eliminating level 350 characters with average equipment.

Why Balgass is so special: Balgass is the only source of Loch's Feather in the game, and this drop only occurs when the Crywolf event fails (meaning the monsters destroy the Crywolf altar). Loch's Feather is one of the mandatory ingredients to create Third Level Wings (Wing L3).

Notable drops from Floor 7:

• Loch's Feather (Balgass only, when Crywolf fails)
• Jewel of Life (excellent rate)
• Jewel of Soul (excellent rate)
• Jewel of Bless (improved rate)
• Level 9+ sets with options
• Level 9 weapons with multiple options

How to face Balgass on Floor 7:
1. Check if Crywolf has failed before going (Balgass appears empowered)
2. Gather a group of at least 3-4 well-equipped players
3. Position the Elf as support with Bless and Defense buffs
4. Main DK in front with +11 or higher shield
5. DW(s) attacking from range with Meteor and Chain Lightning
6. When Balgass dies, loot immediately — other players can take it

Floor Progression Strategy

The ideal progression through Lost Tower follows this pattern:

Level 150-200  → LT1 and LT2 (Zen and Jewel of Chaos farming)
Level 200-250  → LT3 and LT4 (Sets and Jewel of Soul/Life farming)
Level 250-300  → LT5 (Thunder Hawk Set and Jewels farming)
Level 300-330  → LT6 (best cost-benefit for Jewels)
Level 330+     → LT7 (maximum drops, Loch's Feather, Balgass)

Maximizing Your Returns

Party vs. Solo:

• Solo is best for collecting loot quickly on floors you can clear without difficulty
• A party of 2-3 players is ideal for Floor 7 (Balgass) and to speed up clearing Floors 5-6
• An Elf with buffs in a party increases all members' damage by 20-40% depending on skill level

Support Equipment for Farming:

• Use items with +Zen option (Luck + Double Damage help indirectly by increasing clearing speed)
• Always maintain Excellent options in your main weapon and armor slots
• Sets with HP Recovery option reduce potion consumption on upper floors

Lost Tower is one of the best farming destinations in MU Online S6 for characters in the level 150-350 range. With the right strategy per floor and the proper build for your class, you will accumulate Jewels, valuable Sets, and prepare your character for even more challenging maps like Tarkan and Icarus.
