For the past several months, Zeri has been a champion that has been “estranged” from players. The reason lies in the fact that Zeri has become extremely weak after a series of nerfs from Riot Games. As a result, Zeri’s selection rate in the single-rank environment has dropped dramatically.
However, in the 2023 Pre-Season, pro players found a way to use Zeri effectively. Most recently, Hanwha Life Esports player Viper has consistently used Zeri on Adaptive Shell Jak’Sho and Serpent Ax.

The first thing that makes Zeri good use of Adaptive Cover Jak’Sho is that this champion possesses high mobility. This element helps Zeri move flexibly in combat and accumulates for this equipment extremely effectively. Moreover, the skill or health regeneration from Jak’Sho also helps Zeri deal extremely good damage.

Next, the gameplay of buying the Serpent Ax on the first item of equipment allows Zeri to build a resistant item like Jak’Sho and still deal effective damage. Both of these items provide great healing for Zeri, so this champion will stay in fights better than other ADCs.
A small note for League of Legends players is not to buy Jak’Sho as the first major item with Zeri. Instead, the Serpent Ax and Runaan’s Rage should be prioritized to ensure the ability to clear minions. Gamers should only buy Jak’Sho when they own 2 Legendary equipment before.

With the gameplay on Adaptive Shell Jak’Sho, Zeri will become a Gladiator with long range and high mobility. If you want to find a new way to play for Zeri, then Jak’Sho is the perfect item at the moment.
