Welcome summoner, you have found yourself on the LoL signature maker, where you can make your own signature featuring the stats you have managed to achieve in the ranked games. Just like this:
TIPS: To find a champion quicker, open the selectbox and press the first few letters.
INFO: It will only work if you are placed in Season 4 ranked! The site currently fetches data from the EUNE, EUW and NA servers directly from the Riot API. Your signature should load really fast, if you are from one of these. For the other regions, the old LoLKing.net fetcher is still being used.
STATS: There have been 1311 signatures generated in the last 24 hours!
REDDIT: If you have doubts, questions, ideas or bugs to report, do so here: on reddit!
OTHER: Did you not like the signature my little app makes? Would you like more stats and customization? Have a look at RisingCorruption's League of Signatures - a very nice and more customizable signature maker.
