The first Teamfight Tactics Beta Pass ended in July, thus putting a term to our delightful weekly and daily challenges. However, moving with patch 9.16, Riot will implement a new Beta Pass! According to the development team, the new Beta Pass will contain similar missions and prizes. Brace yourselves: if you didn't get the opportunity to obtain your Rift Arena, here is a second chance!
For all of us who already unlocked almost all the content from the previous Pass, this news seems a bit frustrating. However, Blake "Riot Beernana" Edwards explains that "we'll probably shake things up a bit after that." — meaning that we should soon see more "free stuff" raining on the Convergence.
