Art of Weather

The Clima-Tact is the upgraded form of Nami's signature weapon. Created by Usopp, it resembles a steel bowstaff that can be separated into three pieces. Using it along with Nami's knowledge of weather conditons, it has proven to be an effective weapon and put Nami on par with the rest of crew. This page lists and details all the various functions of the Clima-Tact that have either been installed by Usopp or devised by Nami's inginuity that have been revealed so far in the story.

History
Sometime before the events in Alabasta, Nami explained to Usopp a revelation she had over the course of their voyages. Upon examining the monstrous strengths of the rest of the crew, Nami noticed that she and Usopp were pratically weakest ones in the entire crew. Seeing as there was no possible way that they could ever match the strengths of Luffy and the like, and that there will come a time when they alone can no longer depend solely on the help on others but by themselves, she figured that the only way they could compensate is with the use of their wits and some formidable weapons. She thus asked Usopp to give her a weapon so that she could keep up with the others. Upon that request, Usopp gave her the Clima-Tact.

Basics

 * Heat Ball (熱気泡(ヒートボール)) / (Heat Orb): Nami takes the "Heat Pole" and blows into the end of it. A bubble of heat comes out of the other end and drifts along in the air.
 * Cool Ball (冷気泡(クールボール)) / (Cold Orb): Nami takes the "Cool Pole" and blows into the end of it. A bubble of cold comes out of the other end and drifts along in the air.
 * Thunder Ball (電気泡(サンダーボール)) / (Thunder Orb): Nami takes the "Electric Pole" and blows into the end of it. A bubble of electricity comes out of the other end and drifts along in the air.

Party Functions

 * Fine Tempo (ファイン＝テンポ) / (Fine Tempest): Nami puts the three clima tact-staff pieces together to form a triangle. Doves magically exit the triangle.
 * Cloudy Tempo (クラウディ＝テンポ) / (Cloudy Tempest): Two of the staff pieces are attached to each other like a pole, then the third staff is attached poking down to the ground. Nami holds it like a rifle, and flowers sprout from the tip.
 * Thunder Tempo (サンダー＝テンポ) / (Thunder Tempest): The three staff pieces are joined together in a Y-shape. Nami then grabs the two "Y'poles". A small boxing glove bursts out of the single end.
 * Rain Tempo (レイン＝テンポ) / (Rain Tempest): All three of the pieces spout water into the air.
 * Sprinkler (スプリンクラー): Nami spins around on her foot while performing the Rain Tempo.

Offensive Functions

 * Cyclone Tempo (サイクロン＝テンポ) / (Cyclone Tempest): Nami puts the "Heat Pole" and "Cool Pole" together like an X on the top of the "Electric Pole". She swings it like a bat, and the X detaches from the "Electric Pole" spinning torwards her opponent. When the X hits, the hot and cold airs collide and create a massive wind that'll blow her opponent away. The the X will return to Nami like a boomerang.
 * Mirage Tempo (蜃気楼(ミラージュ)＝テンポ) / (Mirage Tempest): Nami use the "Cool Ball" in a dry and hot environment to change the air density and create a mirage of herself. The extreme difference in temperature causes major light refraction.
 * Thunderbolt Tempo (サンダーボルト＝テンポ) /Cloud Zapper (Thunderbolt Tempest in Grand Battle and Grand Adventure): Nami uses "Rain Tempo" and "Sprinkler" to moisten the air. Then she uses "Cool Ball" to make the air cooler. Afterwards, she uses "Heat Ball" to suck up the moisture and the heated air rises. The heat collides with the cold and the air condenses which creates a cloud. Nami continues to enlarge the cloud with "Heat Ball" and "Cool Ball". Finally, she uses a "Thunder Ball" to electrify the cloud. Soon after, a powerful lightning bolt strikes her opponent. With the Perfect Clima-Tact, the lightning is larger and strikes multiple times.
 * Tornado Tempo (トルネード＝テンポ) / (Tornado Tempest): Nami combines the three pieces together into a T. In a bright flash from each end, two clockwork doves burst out and ensnares her opponent. The T starts to spin rapidly until it finally shoots the captured enemy with mighty force. Nami can only use this attack once, because the doves become unusable after the attack.
 * Fog Tempo (フォッグ＝テンポ): Nami used "Cool Ball" against a fire user which will create a massive fog due to the vapor in the air increasing in density from the rapidly heating cold air

Functions

 * Thunder Charge (サンダー＝チャージ): Nami creates a thunder-ball on the end of the Perfect Clima Tact.
 * Swing Arm (風速計(スイングアーム)): Used after Thunder Charge, Nami flings the end section that has been charged into the opponent.
 * Cool Charge (クール＝チャージ): Nami creates a cool-ball on the end of the Perfect Clima Tact.
 * Cloudy Tempo (クラウディ＝テンポ): A completely revamped version of Cloudy Tempo. With this, Nami creates a small cloud capable of producing rain. However, the clouds are too thin to create lightning.
 * Rain Tempo (レイン＝テンポ): A completely revamped version of Rain Tempo. With this, Nami is able to create rain from an already existing cloud.
 * Mirage Tempo Fata Morgana (蜃気楼(ミラージュ)＝テンポ　幻想妖精(ファタ・モルガナ)): An upgraded version of Mirage Tempo that can create multiple images of Nami that imitate her movements and even attacks, though distorted. It creates tall, short, fat, muscular, and normal-looking images of Nami, and disguises Nami herself.
 * Dark Cloud Tempo (黒雲(ダーククラウド)＝テンポ): Nami forms a small, condensed, electrically charged cloud.
 * Thunder Lance Tempo (雷光槍(サンダーランス)＝テンポ): Using a cloud previously formed with Dark Cloud Tempo, Nami creates a lightning bolt going directly from the cloud to her Perfect Clima Tact.
