Teamfight Tactics is an autobattler made by Riot Games utilising the vast roster of champions available in League of Legends.
By choosing different champions with the same classes and complimentary spells, you can unlock powerful synergies that allow for bonuses such as greater attack speeds, increased armor or stunning opposing champions on the field.
Items can be found and equipped to maximise the potential of individual champions, granting different benefits depending on what you equip and how you combine base items.
The classes were expanded upon with the introduction of the second set of champions in Rise of the Elements. Specific lements and origins were added alongside classes, increasing the number of trait bonuses and adding variety.
