Lee Sin is widely acclaimed by many seasoned TFT players as an incredibly potent frontline force.
After a period since its inception, the TFT meta has distinctly split into two styles: reroll and fast level 9. Numerous champions have shone brightly due to the reroll strategy, such as Sett, Nidalee, Ezreal, Ryze... and most recently, Lee Sin in the 6 Dragon Warrior lineup. So, how can one effectively utilize this composition? Let's delve into it.

Firstly, understanding the mechanics of the Lee Sin - Dragon Warrior synergy is crucial; leveraging Lee Sin's knock-up and wide-area damage as the primary damage source. Therefore, Lee Sin's positioning is paramount to optimize the damage output. Alongside Lee Sin, Yasuo also serves as a crucial late-game powerhouse that players need to pay attention to.
In the early game, players will start with inexpensive yet quality Dragon Warrior units like Sett, Ashe, or Karma. You can activate the 3 Dragon and 2 Guardian synergy with Taric and Leona to bolster the team's resilience. The Dragon Guardian Seal at this stage should be given to Karma as she utilizes Guardian Angel and Infinity Edge (Lee Sin's 'disruptive' item) effectively. If you only have an Infinity Edge, consider combining it with the Dragon Guardian Seal for Sett.

In the mid-game, you need to supplement key units like Lee Sin, Swain, and even Volibear if possible to quickly reach the 6 Dragon Warrior milestone. If you can't find these units, at the very least, you need to roll for Lee Sin to serve as the primary damage dealer. You can utilize other inexpensive, high-quality units like Ezreal, Taric, Leona to sustain until reaching the 6 Dragon Warrior milestone.

After reaching level 8, it's crucial to optimize your team composition with Yasuo and Neeko to unleash their full potential. While rerolling for a 3-star Lee Sin at level 7 previously, consider acquiring Swain as well, as he presents a significant damage threat in the later stages of the match. As mentioned earlier, apart from upgrading champions, it's imperative to observe the opponent's team composition and position Lee Sin strategically.

Regarding technology core choices, upgrading the Dragon Warrior's Heart is paramount as it helps players save slots in the team composition and achieve the 6-champion milestone faster. Additionally, the New Life Core aligns perfectly with this team composition as champions receiving the Dragon Warrior's Seal will have a substantial amount of health. Furthermore, equipment-providing cores should also be prioritized as Lee Sin, being the primary carry, greatly benefits from disruptive items.
