The following units will swiftly empower your team in Chosen Arena without the need for any items.
Talon
Among the Assassins, essential champions like Katarina, Shaco, or Akali demand equipped items for effective damage. Even a support-type champion like Ekko benefits from items like Frozen Heart or Morello's Evil Tome to unleash maximum power from abilities. However, in the case of Talon, this chess piece requires no gear to deal efficient damage, allowing players to secure early-game victories without item investments.

This makes Talon an almost indispensable unit in the Assassin lineup, helping you overcome the challenging early-game phase remarkably well. Furthermore, you won't need to itemize this unit, saving equipment for other key champions with the potential for greater power spikes. Even when played in the Empire comp, Talon's lack of item dependence ensures swift elimination of backline threats, allowing the primary damage dealer (Samira) to benefit from the Warlord buff.
Janna
Speaking of Janna's strength, her extreme versatility is perhaps the most accurate descriptor. Having Janna in your lineup means having a powerful healer who lightly counters Assassin units with her knockback effect. Moreover, Janna's tribe - class combination adds the ability to 'hack items' from the Recyclers tribe and recharge energy with the Scholar class. Just having Janna on your team grants players a plethora of power.

Remember that all of Janna's strengths come from her abilities and effects from her tribe - class combination. Even if you want Janna to heal more, simply activating the Artisan class is more than enough; there's no need to equip additional items to boost skill damage. With these advantages, Janna is the perfect piece to protect backline carries as well as ensure the longest possible lifespan for tanky units.
Yuumi
Once underrated during testing phases, Yuumi proved to be an incredibly powerful unit when Teamfight Tactics Season 6 officially debuted. Providing shields for attached units, Yuumi can make your backline carry extremely difficult to defeat. Furthermore, Yuumi's abilities offer players a highly potent area-of-effect crowd control solution. This factor essentially suits any team composition and every match.

Not stopping there, attaching to high attack speed carries allows Yuumi to quickly recharge energy without the need for items. With such immense versatility, you also don't need to equip magic damage items for Yuumi to deal extra damage. In conclusion, with significant versatility and the ability to recharge energy without relying on items, Yuumi is a tremendously strong choice in the late game, even without any equipped items.
