The Annoyance of Sett and the Big Boss Core
In Season 9 of Teamfight Tactics, Sett proves to be an exceptionally strong frontline tank. Moreover, the basic damage from Sett’s abilities is not insignificant, making him a key player in compositions like Ionia and Brawler. Therefore, players in the LPL region have found ways to leverage the Big Boss core to transform Sett into a champion that is both resilient and capable of high damage in the mid-game.

Building the Sett – Brawler Composition
The best way to start with this playstyle is to utilize the 3 Ionia synergy with Sett, Irelia, and Jhin. Warwick will be a perfect addition at level 4 when activating the 2 Challenger and Brawler synergies. At level 5, players can consider bringing Ashe or Akshan onto the board.

By the mid-game, players should shift towards the 4 Brawler synergy by adding Darius or Garen. These units can execute opponents very effectively to maximize Sett’s basic damage. If players can acquire Yasuo or Kai’Sa at level 7, they should aim for the 4 Challenger synergy.

In the late game, Aatrox and Nasus will be good additions for players to reach the 6 Brawler threshold. Strong single-target damage dealers or units providing good crowd control, such as Bel’Veth and Sion, are also good choices to compensate for the weaknesses of Brawler champions. However, players may aim for level 9 and use multiple 5-cost champions if they have a long winning streak and feel that Sett is no longer strong enough.

Besides the Big Boss core, the Healing Orb or the Heart of the Dilemma are very fitting for this composition. In terms of item choices, Sett will need the Justice Hand and 2 tank items to survive fights and deal damage effectively. Physical attack items can be equipped for Bel’Veth in the late game.
Conclusion
With the Big Boss core, Sett can become an excellent tank and damage dealer in the mid-game. This unit can help players maintain health and quickly reach high level thresholds. If players need a fresh strategy for climbing ranks, the Big Boss Sett is incredibly suitable.
