This weapon was first introduced when the Straw Hats finally reached Alubarna, in which the Clima-Tact is revealed to be a weapon that greatly resembles Nami's original three piece bo-staff, with the segments made of hollow blue steel. Despite being shown earlier, the Clima-Tact was not fully shown until Nami's battle against Miss Doublefinger. Each piece of the Clima-Tact also has a button on it 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.
However, due to a misunderstanding of Nami's preferences, the Clima-Tact was originally designed by Usopp for party uses and parlor tricks. But with a little creativity on Nami's part she was still able to turn the Clima-Tact into a powerful tool in battle, despite these flaws. 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".
