Art of Weather/Fourth Clima-Tact

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

Appearance
In its base form, it is a short, dark staff with white striped parallel lines and a round 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 upgrade 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 to create it.

Both Usopp and Franky used the knowledge they gained during the two years of training to incorporate all but one gadget of Weatherian technology that Nami gave to Usopp in  order to make a lighter, more compatible weapon for Nami. The "Magic Wand" (which Usopp could not comprehend) was not implemented into the new weapon. Usopp worked on upgrading the Clima-Tact during the trip between Punk Hazard and Dressrosa.

Unlike her original wooden staff or the previous Clima-Tact models, it does not need to be carried around in three separate parts due to its ability to extend and contract, thus negating the need for Nami to assemble the parts together or separate them.

It seems like twirling is how Nami uses 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 four dark clouds after twirling her weapon. The clouds are capable of producing lightning. Visibly impressed, Raizo refers to this as "marvelous ninjutsu."

Other Uses



 * Grow Up (成長（グローアップ）): By incorporating the growth abilities of the Pop Green into the new staff, similar to his own Kuro Kabuto, Usopp designed the New Clima-Tact to also change size. Whenever Nami squeezes the handle she can extend the size of the staff, where the new length is determined by the amount of pressure that is applied.
