Changing the look of skills

I'm not sure what you mean, could you please clarify?

What I meant was that if you edit the .wz files for the skill animations, you could make them look however you want, but only you would see the changes, because only you have the edited .wz files. Other people would see the normal skill animations, but you would see any skill anyone used with the animations you edit in. This may cause the game to crash is is probably against the ToU though.

Maybe the idea for the skill seens not possible, but when you go change your hair or stuff, there's a window that shows how it will look like if you change, same could go with the skills, your character using the skill(showing how it will be if you change).

Edit: maybe to the codes it's impossible i don't really mind, just a idea, not really important or something that i want much.
