The Mage's Staff's handle is black with a gold pommel and a white ring near the tip and base. The lower half of the staff's head is bent and blue and has a blue "collar" with white edges folded over it, resembling Donald’s sailor suit.
The upper half sports a brown hat with a long, curled tip and a black, silver-buckled belt around it, similar to the hat of a classic Final Fantasy Black Mage.
In Kingdom Hearts II, the Mage's Staff has a red pommel, grey rings on its handle, the blue sections are dark violet, and the hat is a slightly darker shade of brown.
In Kingdom Hearts 358/2 Days's Mission Mode, the Mage's Staff is Donald's default weapon. As such, it needs no Gears to be equipped. The ground combo begins with a step forward and a vertical slash downward, followed by horizontal slash to the right with a 360 degree spin.
The aerial combo consists of a vertical slash downward, followed by a vertical slash upward, and finishes with a spinning slash starting at Donald's head.
