|“There's a secret message engraved on it. All these years, I had no idea.”|
|— Wu, "Ghost Story"|
The Staff of the First Spinjitzu Master was a staff that belonged to the First Spinjitzu Master. Shortly before his death, he engraved three clues on the staff that was passed to Wu to be sure that it fell in good hands; unfortunately, the Ghost Warrior Morro received the item and later retrieved the Realm Crystal from the Tomb of the First Spinjitzu Master.
At some point, the staff would be recovered by Wu once again. However, after Wu was lost in time, the staff would disappear once again.
At some point before his death, the First Spinjitzu Master engraved three symbols onto his staff that gave the location of his tomb, and passed it on to his youngest son Wu. He hid the other one in his tomb.
Master Wu used his staff throughout the first, second, third, and fourth seasons as a defensive and offensive weapon, oblivious to the three symbols engraved in it.
After possessing Lloyd, Morro goes to Steep Wisdom tea shop looking for Master Wu and the Staff. After a battle between the Ninja and Wu, the staff is dropped over some dust, revealing the engraved symbols. Both Wu and Morro are surprised at this, and the struggle continues. Master Wu manages to retrieve the staff, and he, the Ninja, and Nya escape on the Destiny's Bounty.
Morro chases the Destiny's Bounty on his Dragon to get the staff back. He lands on the ship and attacks the Ninja. While Jay, Cole, and Nya (as Samurai X) try to fend him off, Wu, Kai, and Zane brought it to their quarters in an attempt to print the symbols on parchment paper. However, despite their efforts, Morro gains the staff and flies it away. Luckily, Wu managed to make an imprint of the message before giving up the staff, which is later deciphered by Misako, who reveals that the first symbol means "Airjitzu."
Later that night, Morro walks into a bar, where he lays out the staff on some chalk, revealing the symbols. He then summons Wrayth, who may have helped him figure out the first symbol.
The Ninja see that the last symbol refers to The First Spinjitzu Master's Tomb.
The Ninja, Morro, and his Ghost Warriors go to the Tomb of the First Spinjitzu Master. After the Ninja complete the first challenge, the second challenge appears to be to obtain the First Spinjitzu Master's other staff. They try extremely hard to get it but no matter how hard they try, it is impossible. Then Cole realizes that they have to think about the clue, "A Spinjitzu Master cannot," meaning that since they are all Spinjitzu Masters, they were never meant to get the staff.
When Morro returned to Wu, he readied the staff but lowered it after Morro warned him about Yang’s intentions.
Wu uses the staff in his battle against Acronix. After Wu is struck with Acronix's Time Punch with the use of the Forward Time Blade, Wu attempts to defeat Acronix but is knocked over the side of the structure, forcing him to grab a branch while the staff falls to the ground below.
At some point after the Ninja's battle with Acronix, the staff would be recovered.
In a hallucination of Wu's, he uses his staff to defeat two Vermillion warriors.
Both the present and past versions of Wu would use the staff. After Wu remained on the Iron Doom to deal with Krux and Acronix, the three of them would become lost in time. After Wu escaped, the staff disappeared.
In the show, the Staff of the First Spinjitzu Master resembles an ordinary, wooden Nin-Jô, the main difference being the three, nearly invisible symbols carved into its side. However, in the sets, the Staff has a golden and more ornate appearance, additionally being longer.
- In "Battle Between Brothers," Garmadon breaks Wu's staff by shooting fire at it with the Sword of Fire. This could have been either a different staff, or Wu repaired it.
- While Master Wu was transformed into Techno Wu, it's unknown if the staff he wielded was the First Spinjitzu Master's staff or just a black metal replacement.
- The staff disappeared after the events of Season 5 and Wu is not seen holding it in Season 6. The staff reappeared in "Day of the Departed" and Season 7 when Wu held it.
