I am sure many of you here would have already known about installing custom champion skin, but nonetheless I would still provide some details about it. Basically custom champion skins are skins that are created not by the Riot Game community and instead by the other LoL players around the globe. These skins, once installed will affect you and only you. Other players will still see you with the default skin.
A guide to installing these skins can be found here:
A guide to installing spell and particles can be found here:
These guides are meant for the NA and EU servers of LoL, so in our case, our game path directory would be \Garena Messenger\Apps\LoL\.... so on.
Similarly, even though some of the spells may look different after installing these skin, they are purely visual and the effects are the same.
Here are some examples of really really cool skins which I have found. All these skins are gotten from http://leaguecraft.com/skins and I take no credit in the creation of these skins. Also, this is only a small portion which I have filtered out from the thousands of custom skins found on Leaguecraft. My opinion may be different from yours.
Tryndamere (Note: There seems to me that theres a bug in this skin when I used it. Theres a black line extending out of Cloud's body, not sure if these applies to only some people thou)
More will be added if I find other good ones.
Once again, this list is not exhaustive. Please do check out the full list of custom skins at the Leaguecraft website.
WORD OF CAUTION: I did not try out most of the skins here, so I would not know if they are bugged or not. If you experience some problems while using the skin, please do NOT post your problems here. Instead go to the specific link whereby you downloaded the skin and read the comments down below, you will have better luck there. I HIGHLY RECOMMEND anyone who wants to use these skin to try them out in a custom single player game first before using them in a normal game in case some problems arises and your game crash.
On a sidenote, if anyone of you here have awesome custom skins to share, you can also post your skins here.
