A massive Teamfight Tactics 12.12 B-patch was released by Riot, reducing overperforming champions and comps while buffing the underperformers. 

Patch 12.12 runs for a total of three weeks due to a summer break at Riot. Not wanting to leave the meta in its post-hotfix state, according to game design director Stephen “Mortdog” Mortimer, multiple traits, champions, and items were hit with buffs and nerfs. Patch 12.13 is scheduled to drop on July 13 and will contain an Aurelion Sol fix.

A bug fix was applied to Crown of Champions, removing the option for players to toss onto the battlefield during combat. Dragonmancer Heart was removed from the Silver tier Draconic Augments. And Astral Soul was removed as well. 

Here’s every TFT Set Seven 12.12 B-patch balance change, according to Mortdog and Riot Kent in the B-patch Patch Rundown

A nerf was applied to the Assassin trait in that players can bait Assassin units. Cannoneer vertical received multiple buffs and verticle Whispers was buffed as well. Revel was toned down slightly and Scalescorn was adjusted to nerf two Scalescorn but buff six Scalescorn.

Dragonmancer was hit hard with multiple nerfs targeting six Dragonmancer comps and one-star Dragonmancer units. The trait has been exceptionally strong throughout all stages of a game and will now require players to hit their units and two-star them.

Lillia was given significant buffs via a bug fix and a mana buff that leaves her as a viable option for Blue Buff. Xayah was hit with multiple nerfs to her base damage and feather AD percent. Vladimir was given a significant buff for Astral comps and early game Mage comps. And Ornn got nerfed via stun damage and attack speed slow duration. 

Two dragons were adjusted in the TFT Set Seven 12.12 B-patch. Idas has been the go-to frontline tank dragon, according to Mortdog, resulting in the Shimmerscale dragon getting multiple nerfs. And Sy’fen received multiple buffs, in conjunction with the Whispers trait buffs.
