Enemy/War icon change

[Antoinetta]

Hi there, 

I wanna ask how can I edit clan war icon (two fists)

In which file is that possible?

Sorry for my english   (")_(O.o)_(") 

[L2J NexuS]

File : "L2UI_CH3.utx"
Texture name : "Pledge.war_double"

One first : "Pledge.war_single"

You can edit it via L2Tool, just open the utx file, export the texture (The texture, not the whole file.) , edit it and then just import it back.
( You don't have to decrypt the whole utx file if you don't export it for Unreal. )
