This week’s Teamfight Tactics patch 12.15 has arrived, and the patch notes for the League of Legends-flavoured autobattler’s latest update include some important buffs for a couple traits. Shimmerscales and Trainers are both getting beefed up in different ways, and so are a selection of champs. The latest patch also adds in some new pool party Umbra variants that you can either buy or crack open in random eggs. Aurelion Sol, who figured prominently into the last couple rounds of TFT patch notes, seems to have calmed down for now.

Riot says it’s adjusting the Trainer trait’s hungry frog, Nomsy, who grows as she devours delicious ‘Snax’ picked up during rounds. The idea behind the changes is to require Trainers to protect and care for Nomsy early on, with promise of her becoming a formidable force late in the game.

Here are the TFT 12.15 patch notes, straight from the Riot horse’s mouth.
