I will attempt to change the sprite of Mistress MVP to be displayed as Detale MVP instead.
Benefits:- Bigger MVP sprite means easier to use single target attack (e.g.: Asura). Less likely to mis-click and accidentally attacked the slave instead
- Detale MVP also comes with lots of sound effects in various state: Idle, Standby, Chasing, etc... making it easier to locate the MVP. Even though, you may not be in visual range of the MVP; the loud noise that it continuously emits could be heard beyond the immediate screen.

1. Download and install the necessary programs below.
a. GrfBuilder (to extract data)
b. ROUnicode (convert Korean language to Unicode format)
c. Free RAR Extract Frog (to unpack .rar files)
d. Java SE Runtime Environment (to run .jar files; i.e. ROUnicode)
Download GRFBuilder and ROUnicode (For this purpose SPR_Conview is not necessary)
Download Free RAR Extract Frog Download Java SE Runtime Environment2. Using GrfBuilder,
Open sdata.grf (C:\Program Files\Ragray\sdata.grf)

3.
Extract All the data to a temporary folder. (C:\MyTemporary).

4. Run ROUnicode and convert data from Korean language to Cp1252.

* If you do not see Korean characters, then you will require some setup to be able to display the characters. For Windows Vista (it should already support Korean language by default). For Windows XP,
check this. For other platforms,
check this.
Before conversion (i.e. still in Korean language)

After conversion (i.e. in Cp1252/Unicode)

5.
IMPORTANT: Make sure that the data folder is in the same directory as your ROCreate the following folders:
C:\Program Files\Ragray\data\sprite\¸ó½ºÅÍ

6. Under C:\MyTemporary \data\sprite\¸ó½ºÅÍ is where all monster SPR and ACT files can be found. Find the files detale.spr and detale.act.

7. Copy both the files detale.spr and detale.act and then paste them in C:\Program Files\Ragray\data\sprite\¸ó½ºÅÍ

8.
IMPORTANT Rename detale.spr and detale.act to mistress.spr and mistress.act respectively.

9. FINITO! Just load RagnarokOnline, and find the Mistress MVP. She will appear instead as a Detale MVP
on your screen only. (Other players will continue to see her as Mistress MVP aka a small bee). The sound effects and animation will follow Detale MVP, but the Mistress MVP skill, experience, HP, Stats, etc will remain unchanged.

10. You could also change the slaves of Dark Lord (which looks almost similar but are known as Dark Illusions) into a less obvious monster- say a Picky.
