Newbie trying to edit grf

[kuromaru]

I want to remove the effect of the SPP skill (the bottle being thrown effect) can someone teach me how to do so, or just tell me where and what is the file I need to edit to make
Thank you very much

if i remember correctly this path youve been looking for data\sprite\Àΰ£Á
you just need grf extractor and spr file editor. you can download it on rathena.org
on editing just delete the frame wherein the character throwing the bottle. dont forget to save ofc.

i forgot where the files exactly. its been 9 years since i was on my prime of my editing, scripting and creating a server.

iirc, it uses the item's .bmp file as the drop image. You can search for it in data/texture/À¯ÀúÀÎÅÍÆäÀ̽º/item
