Breakthrough Power of the EDM Trait
In Teamfight Tactics Season 10, the EDM trait possesses a rather special ability to copy skills from allies. Specifically, when selecting an EDM champion with a special item, the remaining units of this trait will cast the skill of that unit after a certain period. The higher the EDM activation threshold, the greater the effect of that skill.

Therefore, some top players have figured out how to leverage this effect to create an extremely high damage output with Lux’s ultimate ability. At that point, EDM champions will continuously unleash the Super Rainbow skill, resulting in massive damage. Combined with the annoying effects of the Supreme trait, the EDM composition becomes even stronger in the late game.
Building the EDM – Supreme Composition.
Players should start with the duo of Nami and Bard in the backline and Gragas, Taric in the frontline. Nami and Bard are both champions that deal good damage and help players get through the early game quite easily. Moreover, Nami is also a great item holder for Lux in the later stages of the match.

During the process of leveling up to level 7, players should add units like Lux, Sett, or Jax to the composition. They will significantly increase damage output and survivability in the mid-game. Additionally, Sett’s strong shielding ability is also a good defensive tool in the mid-game.

By the time players reach level 7, they should proceed to reroll to upgrade Lux and Sett to 3 stars to ensure both survivability and damage output. During this process, champions like Zed and Zac are very valuable additions to reach higher EDM thresholds. After achieving the goal of upgrading the core champions to 3 stars, players should consider leveling up to level 8 and adding Qiyana and Lucian to complete the composition.

With this composition, players should assemble 3 damage items including Infinity Edge, Archangel’s Staff, and Hextech Gunblade for Lux. Having free spell casts from the EDM effect makes building “full damage” more effective compared to energy items. Additionally, defensive items like Warmog’s Armor, Stoneplate, etc., should be equipped to Sett.
Conclusion
With the ability to deal extremely high burst damage, the EDM – Supreme composition is proving to be exceptionally strong at the moment. In the context of everyone rerolling Miss Fortune and Samira, Lux becomes a very effective core champion as she is less contested and has strong power in the mid-game. Therefore, Teamfight Tactics players should find ways to leverage this composition.
