Art of Weather/Fourth Clima-Tact

This Clima-Tact is the fourth upgraded form of Nami's bo-staff.

Appearance
In its base form, it is a short, striped black and white staff, with a round black nob on each side. The nobs on its ends can stretch so it can grow in length from either side, depending on the amount of pressure applied to the center.

Usage
Nami asked Usopp to upgraded her Sorcery Clima-Tact upon reuniting with him on Sabaody Archipelago after the two years she spent studying on Weatheria, incorporating the new technology and knowledge she gained there.

Usopp and Franky used both of their knowledge gained during the two years spent apart to incorporate every technique of Weatheria science except for one called "Magic Wand" in order to make the lighter, compactable weapon for Nami. Usopp worked on the Clima-Tact during the trip between Punk Hazard and Dressrosa.

Nami has a habit of twirling her new weapon.

Battle Uses

 * Mirage Tempo (蜃気楼（ミラージュ）テンポ): Nami has been shown using an upgraded variation of this technique, allowing her to become invisible for an unknown amount of time.


 * Thunder Trap (雷雲の罠（サンダー・トラップ）): Nami creates three dark clouds, in what appears to be a triangular formation. When someone passes through the middle, the clouds electrocute it. Nami was seen pretending to be a ninja by casting a ninjutsu technique to create these clouds by shaking her index fingers, but she mistakenly referred to it as a samurai impersonation. Raizo also refers to this as ninjutsu.

Other Uses

 * Grow Up (成長（グローアップ）): By squeezing the handle of the New Clima-Tact, the weapon grows longer. The pressure of the squeezing determines the new length of the staff.
