Re-rolling with An epic Skin shard in the recipients, should give you a random permanent epic skin.
Now listen before you downvote. while i understand that its free stuffs, but it takes a lot of time to gather keys up. and it mostly gives you cheap skin and sometimes none. last time i played more than a week maybe month to get a 3rd key fragment only to open to get freaking TEEMO, followed by Kassadin then tryndamere. champions i already own now i re-rerolled a 750, a 975, and a 1350 skin. only to get a 750! after so much playing. like i get a lot of S's, but little key fragments.
it would be nice if you re-rolled an epic skin, your chances of getting a similar skin increases by 70%. idk, something like that. [slayer-pantheon-thumbs]
