The Power of the “New” Noxus Composition
Although the effect changes have not altered, Noxus has received quite a few beneficial adjustments in Teamfight Tactics season 9.5. First is the fact that the Void effect no longer encounters bugs, allowing Katarina to move to the backline more easily. Next, the introduction of Mordekaiser also diversifies Noxus’s gameplay.

This allows the Noxus composition in season 9.5 to still prove extremely powerful in snowballing in the mid-game. Players can fully utilize this aspect to secure wins or earn rank points more consistently.
Building the Noxus 2.0 Composition
In the early stages of the game, players should start with inexpensive, quality Noxus units like Samira, Cassiopeia, and Swain. Warwick is also a good choice at level 4 to activate the 2 Challenger threshold and help Samira deal better damage.

By the mid-game, Qiyana is a valuable addition alongside key units like Darius or Katarina. This unit will activate the 2 Void threshold and help Katarina engage the enemy carry fairly easily. Furthermore, if you possess Mordekaiser early, Qiyana will also help this unit deal more damage with the Butcher effect.

At level 7, players should stop buying experience and Refresh Shop to find ways to upgrade Katarina or Darius to 3 stars. After achieving this goal, pushing to level 8 and completing the 7 Noxus composition with Sion is advisable.

With the Legendary choice, Twisted Fate is the top priority when players need to equip multiple carries (Katarina, Darius, Mordekaiser). As for Katarina, this unit will need the Infinity Edge, Lightning Bow, and Crystal Gauntlet. If using Mordekaiser as the carry, players should combine Rapid Firecannon and Crystal Gauntlet for this unit.
Conclusion
With many beneficial adjustments, Noxus is proving to be an incredibly strong composition in the current season 9.5. Therefore, players should make the most of the Noxus 2.0 composition to rank up more effectively in the near future.
