The Clima-Tact is the upgraded form of Nami's signature weapon.
Created by Usopp, it resembles a bo-staff that can be separated into three pieces, just like Nami's old one. Though resilient enough to withstand the impact from Ms. Doublefinger's attacks, its true power lies in its ability to manipulate the climate. This page lists and details all the various versions of the Clima-Tact as well as the various functions of it that have either been installed by Usopp or devised by Nami's ingenuity that have been revealed in the series.
History
Introduced when the Straw Hats reached Alubarna, the Clima-Tact is a weapon that resembles Nami's original three piece bo-staff, with the segments made of hollow blue steel. In the manga, a scene depicting Usopp working on it on the title page of Chapter 165 and on the cover of Volume 23, showed it is colored red. In the anime, however, it is depicted colored blue. Despite being shown earlier, the Clima-Tact was first fully used during Nami's battle against Miss Doublefinger.
Each piece of the Clima-Tact has a button and is capable of creating a bubble of air each with its own different properties. When the pieces are put together in certain combinations and activated by a button located on a piece connected within the combination, they can produce a variety of different results.
Some of these results are useful in a combat situation, others are completely useless in battle. Each of these are called Tempo which, in Italian and Portuguese, is the word for "weather". In the 4Kids adaptation, the majority of these results are renamed Tempest.
