How to Configure Devil Square Individually on MU Server

How to Configure Devil Square Individually on MU Server

Devil Square (DS) is one of the most popular events on private MU Online servers. Rather than simply enabling or disabling the event globally, configuring each level individually lets you balance the player experience to match your server's profile — XP rates, monster difficulty, exclusive drops, and staggered schedules.

This guide covers complete level-by-level configuration for servers based on MuServer Season 6 (GameServer IGC/Zeuthl), the most widely used build for private servers, with additional notes for S4/S5 and S9+ versions.

Prerequisites

Before starting, make sure:

• The GameServer is stopped (never edit files while the server is running)
• You have access to SQL Server Management Studio (SSMS) connected to the MuOnline database
• Recent backups of the database and configuration files are available

Step 1 — Locate the Configuration Files

In Season 6, Devil Square files are located at:

GameServer/
└── Data/
    └── DevilSquare/
        ├── DevilSquare.ini         ← Schedules and general settings per level
        ├── DevilSquareMonster.ini  ← Monsters per DS level
        └── DevilSquareItem.ini     ← Item drops per level (some versions)

1.1 Open DevilSquare.ini in a text editor (Notepad++ is recommended, ANSI encoding).

1.2 Locate the opening section — it will have blocks like:

[DevilSquare1]
Enable=1
StartTime0=00:00
StartTime1=04:00
StartTime2=08:00
StartTime3=12:00
StartTime4=16:00
StartTime5=20:00
PlayTime=15
WaitTime=5
MinLevel=15
MaxLevel=80
MaxPlayers=10

[DevilSquare2]
Enable=1
StartTime0=00:30
StartTime1=04:30
...

Each block from [DevilSquare1] to [DevilSquare5] is independent and can be configured separately.

Step 2 — Configure Schedules Per Level

The most efficient strategy is to stagger schedules so that different DS levels do not open simultaneously, reducing server load and giving players options throughout the day.

Recommended staggered schedule example:

[DevilSquare1]
Enable=1
StartTime0=00:00
StartTime1=06:00
StartTime2=12:00
StartTime3=18:00
PlayTime=15
WaitTime=5

[DevilSquare2]
Enable=1
StartTime0=01:00
StartTime1=07:00
StartTime2=13:00
StartTime3=19:00
PlayTime=15
WaitTime=5

[DevilSquare3]
Enable=1
StartTime0=02:00
StartTime1=08:00
StartTime2=14:00
StartTime3=20:00
PlayTime=15
WaitTime=5

[DevilSquare4]
Enable=1
StartTime0=03:00
StartTime1=09:00
StartTime2=15:00
StartTime3=21:00
PlayTime=15
WaitTime=5

[DevilSquare5]
Enable=1
StartTime0=04:00
StartTime1=10:00
StartTime2=16:00
StartTime3=22:00
PlayTime=15
WaitTime=5

Step 3 — Configure Level Ranges Per DS

Still in DevilSquare.ini, adjust the MinLevel and MaxLevel parameters for each block. For servers using a reset system, replace these values with a reset range if your GameServer supports MinReset/MaxReset fields:

[DevilSquare1]
MinLevel=15
MaxLevel=80

[DevilSquare2]
MinLevel=81
MaxLevel=130

[DevilSquare3]
MinLevel=131
MaxLevel=180

[DevilSquare4]
MinLevel=181
MaxLevel=230

[DevilSquare5]
MinLevel=231
MaxLevel=400

Step 4 — Configure Monsters Per Level in DevilSquareMonster.ini

The DevilSquareMonster.ini file defines which monsters appear at each level. The typical format is:

[DevilSquare1Monster]
MonsterCount=5
Monster0=26    ; Werewolf
Monster1=30    ; Hell Hound
Monster2=41    ; Poison Bull Fighter
Monster3=44    ; Death Angel
Monster4=45    ; Death Centipede

[DevilSquare2Monster]
MonsterCount=5
Monster0=55    ; Hell Spider
Monster1=57    ; Shadow
Monster2=61    ; Balrog
Monster3=64    ; Gorgon
Monster4=66    ; Stone Golem

[DevilSquare3Monster]
MonsterCount=5
Monster0=73    ; Iron Rider
Monster1=75    ; Tantallos
Monster2=77    ; Knucle Scream
Monster3=79    ; Death Gorgon
Monster4=82    ; Queen Bee

[DevilSquare4Monster]
MonsterCount=5
Monster0=87    ; Blood Soldier
Monster1=89    ; Aegis
Monster2=91    ; Rogue Centurion
Monster3=93    ; Necron
Monster4=95    ; Scream

[DevilSquare5Monster]
MonsterCount=5
Monster0=97    ; Blaze Napin
Monster1=99    ; Dark Elf
Monster2=101   ; Great Bahamut
Monster3=103   ; Silver Valkyrie
Monster4=105   ; Dark Coolutin

The monster IDs (Monster0, Monster1, etc.) correspond to the Type field in the MonsterSetBase table of your database.

Step 5 — Adjust Drops via SQL Server

To configure exclusive drops per Devil Square level, open SSMS and run the following queries against the MuOnline database:

5.1 — Check current DS drop table:

USE MuOnline
GO

SELECT *
FROM T_EventDropItem
WHERE EventType = 2  -- 2 = Devil Square
ORDER BY EventLevel, ItemIndex

5.2 — Insert an exclusive drop for DS1 (e.g., Jewel of Bless):

INSERT INTO T_EventDropItem (EventType, EventLevel, ItemIndex, ItemSubIndex, ItemLevel, Durability, DropRate)
VALUES (2, 1, 14, 0, 0, 255, 10)
-- EventLevel 1 = DS1, ItemIndex 14 = Jewel of Bless, DropRate 10 = 10%

5.3 — Insert a drop for DS5 (e.g., Box of Kundun +5):

INSERT INTO T_EventDropItem (EventType, EventLevel, ItemIndex, ItemSubIndex, ItemLevel, Durability, DropRate)
VALUES (2, 5, 14, 15, 0, 255, 5)
-- ItemSubIndex 15 = Box of Kundun +5, DropRate 5 = 5%

5.4 — Remove an unwanted drop from a specific level:

DELETE FROM T_EventDropItem
WHERE EventType = 2
  AND EventLevel = 3
  AND ItemIndex = 14
  AND ItemSubIndex = 0

Step 6 — Configure via SQL Table (Servers with Database-Stored Config)

Some MuServer versions (especially newer builds based on S6EP3 and above) store DS configuration directly in the database:

USE MuOnline
GO

-- Check current settings
SELECT * FROM T_DevilSquareSetting ORDER BY DSLevel

-- Update DS3 opening schedule
UPDATE T_DevilSquareSetting
SET StartTime1 = '08:00:00',
    StartTime2 = '14:00:00',
    StartTime3 = '20:00:00',
    PlayTime = 15,
    WaitTime = 5,
    MinLevel = 131,
    MaxLevel = 180
WHERE DSLevel = 3

-- Temporarily disable DS4
UPDATE T_DevilSquareSetting
SET Enable = 0
WHERE DSLevel = 4

Step 7 — Configure Player Limits Per Level

The MaxPlayers field controls how many players can enter each DS instance. Adjust according to your server's capacity:

[DevilSquare1]
MaxPlayers=15   ; Beginner DS, more crowded

[DevilSquare2]
MaxPlayers=12

[DevilSquare3]
MaxPlayers=10

[DevilSquare4]
MaxPlayers=8

[DevilSquare5]
MaxPlayers=6    ; High-level DS, more restricted

Step 8 — Test the Configuration

After saving all files:

1. Start the GameServer normally
2. Log in with a GM account and use the command /dsopen [level] (or the equivalent for your server) to open DS manually
3. Enter the DS with a character within the configured level range
4. Verify that the correct monsters appear
5. Wait for the event to end and confirm drops are occurring

Common Troubleshooting

DS does not open on schedule:

• Confirm the Windows server clock is correct (run w32tm /query /status in CMD)
• Verify that Enable=1 is set for the level in question
• Check the log at GameServer/Log/ for errors related to DevilSquare

Players cannot enter:

• The character may be outside the level range (MinLevel/MaxLevel)
• The DS may have already reached MaxPlayers
• Verify that the entry item (Invitation of Devil Square) matches the correct DS level

Server crashes on startup after configuration changes:

• Revert to the DevilSquare.ini backup
• Open DevilSquare.ini and look for lines with special characters or extra spaces in numeric values
• Ensure all blocks from [DevilSquare1] to [DevilSquare5] have all required fields filled in

With these individual configurations, each Devil Square level will have its own schedule, monsters, drops, and player limits, providing a balanced and diverse experience for all player profiles on your server.
