Yeah it is, I just prefer having the ability to choose what it looks like. But I guess I could try another way of changing it. I mean I found a way to change the 99 aura so it should be the same thing with the valk helm.
Nope, not the same thing at all.
Auras are easy for anyone to edit because none of the file names are in korean. Whereas all the headgear/weapon/class/monster/whatever sprite files and directories contain korean, and unless your computer is set to English wthout any Asian languages installed, RO wont be able to read those files and directories.
I've had my computer set to Japanese for a few years now in order to play import games without a hitch, but I've had to change it back to English in order for my sprite mod to be recognised.
