Item Stacking and Clarity
- We took a pass at all the items to ensure that they stack in a sensible way, and that we’re informing you when they don’t. Adding copies of items that do not stack will now cause them to bounce off any champion they are placed on. Unique items will be labelled as such in their tooltips. All items listed below are not intended to stack.
- Youmuu’s Ghostblade
- Knight’s Vow
- Frozen Mallet
- Yuumi
- Blade of the Ruined King
- Darkin
- Phantom Dancer

Wild
- (4): All your allies gain 12% AS per attack (up to 5 stacks) AND their basic attacks can’t miss.

Music
- Teamfight Tactic's new music will change based on what phase of the game you're in. For instance, during shopping phase the music is calmer and less busy, but as battle phase starts the music transitions into a more energetic combat driven style. There are also 3 different “chapters” of music: the first chapter goes from the beginning of the game to when first player is knocked out. The second is from that point until there are only 3 players left. Then the final chapter brings us home.
