League of Legends Achievements


Q: I made a pentakill in 2003 and I didn't get the achievement for it

A: Probably, but our datas - according to the Riot API - only start as of May 1st, 2014 and there is nothing we can do about it. Sorry.

Q: I'm in North America and my achievements are appearing very slowly

A: Our research facility is located in EUW, therefore all intercontinental research will be slower than in Western Europe, sorry.

Q: I finished the season as gold or higher but I don't have the victorious achievement

A: Those achievements only appear after you have played at least one ranked game during the new season.

Q: I have an idea of a new achievement

A: That's great, please let us know about it.

Q: Which kind of games does Poro Laboratories use to calculate achievements?

A: Ranked, only. That's in line with Riot's idea to only have ranked games appearing publicly.

Q: Can I use your datas ? How ?

A: Sure and we even have an API, just contact us.

Q: In the list of rarest achievements, some are a yellow color. What does this mean?

A: Those are the legendary achievements. They are the most impressive ones or the harder to obtain, like scoring a pentakill.
