Teamfight Tactics will get an injection of new content with the upcoming mid-set update titled Neon Nights. In addition to the changes to the Hextech Augments that are coming, Neon Nights brings over 20 new champions to the game along with new Origins and Classes. Some champions will remain from Set 6 into Set 6.5 with completely new traits, while some will leave TFT altogether.

Here are all the new traits and champions that players will get their hands on in Set 6.5. The update is scheduled to go live alongside Patch 12.4 on February 16.
