Fellow Teamfight Tactics players, write this date on your calendars: you have until Patch 9.20 to complete the second beta pass of the season — and acquire the related rewards. Since patch 9.19 should be shipped to live servers on September 25, we should expect patch 9.20 and the end of the current beta pass on October 9.
Keep in mind that each new beta pass resets your progression, meaning that all rewards that weren't acquired are actually lost... Fancy having the Draconic Area? The Runic one? Well, you just have to play and complete missions... before Patch 9.20.
Good luck!
Riot Mort just tweeted about it: the Teamfight Tactics Beta Pass will return with patch 9.16.
