Following Rise of the Elements, Teamfight Tactics is going to undergo a LOT of different changes. We already revealed that a legion of new champions, origins, and classes were going to be implemented, but we also talked about board interactions...
That's right! The four elements are going to be directly introduced into TFT's board — but how?
Well, that's quite easy: some hexes will now randomly be infused by the power of the four elements: Infernal, Ocean, Wind, and Mountain. In a completely random way, some of these elemental hexes will appear at the start of each round. If you place a champion on one of these hexes, he will benefit from the following bonuses:
The first elemental hex will appear at the end of the first Carousel phase, the second one during the 3-1 round.
Be cautious about these hexes: they will act as an item, and will thus occupy one of the item slots of your champion.
As detailed in scarra's video, each player will benefit from the same hexes to make things balanced. Hexes are also persistent until the end of the game.
