Top 5 Rarest Skins

For me , the top 5 rarest skins in League of Legends are The 5

Victorious,PAX Twisted Fate ,Judgement Kayle,UFO Corki and Urf the Manatee Warwick.

The 5 Victorious Skins

The Victorious Skins are skins that can be achieve only at the end of one season.In season 1,the Victorious Jarvan was release.In season 2 was Victorious Janna.Season 3 was Victorious Elise.Season 4 was Victorious Morgana and the last is Victorious Sivir. I chose these because you would never be get one of these skin except if you meet what it is needed to get it.

 PAX Twisted Fate

It's skin was released in 2009 at the PAX event.It would never be released again because this event just happen once i think that's why i chose it as rarest skin.It was only release in season 3 and season 3 cannot be go back.

Judgement Kayle

Judgement Kayle was a skin that is a reward in Season 1.So i chose this as rare because  you cannot get this skin or you cannot purchase it unless you played the season 1 of League of Legends. 

UFO Corki

UFO Corki was a skin that pilots an UFO ship.This was given when you sign-in in League of Legends before January 14,2010. You cannot get this skin if you do not simply sign-in in League of Legends before the date.

Urf The Manatee Warwick

Urf the Manatee Warwick is a normal Warwick with Urf in it's back. This skin was released on April fools day. This was a unique skin. You cannot get this skin unless you play the game before April 2010.
