@Riot Warning to all New & Vet league players that dont know this.
This is a warning to all League players for those who don't know about this already. Please do not use the Mod Skin LOL Professional, It is a program that is highly illegal and can get you banned. The reason being is because it takes skins that have already been made by Riot and lets you use that skin locally. meaning only you can see it but because the skins that it's letting you use are not only copyrighted and changes how you play, I highly recommend you don't. I recently asked Riot support about this and they said it violates the terms of service because of these reasons.
So if you are a person who likes to be able to have custom skins do not use any third party software similar to this. You are risking your account by doing so. Here is more information on the third party guide if you haven't done so before.
