I do not have any codes from Pax Prime 2014. I am just spreading the word that Pax Prime is happening right now, and the codes will expire on September 5th @ 7:00 PST.
My only suggestions for grabbing codes is to check /r/leagueoflegends and /r/LeagueOfGiving, but it doesn’t look like there is anything there yet. I am sure some streamers will be giving codes away too, as well as other bloggers and players in general on the league of legends forums.
The codes being given away at Pax Prime are:
Arcade Miss Fortune:
And more Riot Wards:
Happy hunting and good luck getting some codes! Again, the Pax Prime 2014 event is August 29th – Sept 1st, and all of the codes from it are expiring Sept 5th.
Another deadline to be looking at: Riot Kayle, Riot Blitzcrank, Riot Graves and Riot K-9 Nasus are in the League of Legends store only until August 31 for 975 RP each. Be sure to grab a riot skin before they’re gone!
