a good tip to get over 6300 ip champions with less ip

if you have all the champs that are under 6300 ip buy 3 random champion shards (1700x3) so you'll pay only 5100 , reroll these champions , then you will get a randome 6300 permanent champion for a less price , who knows maybe you will get the 7800 newest champ , HAVE FUN !! (ps: it will automatically give you a champion that you don't have so don't worry about this detail)
