What's the name of the stick held by the witch?

The stick held by the witch is called a wand.

Generally speaking, there are short wands used by one hand (English name: magic wand, also known as magic wand) and wands used by two hands (English name: magic staff, also known as wand, wand), which are nearly half a meter long.

There is no difference between the above two wands in other respects. In some works, the use of two-handed wands may increase the power to release magic, while one-handed wands are allowed to be used as dual weapons.

There are no magic sticks in the real world, but there are toy sticks for pure play, or props for making movies, cosplay or models.

Staff:

Magic release needs media, including hands and spells, so the staff is one of the media to release magic.

Most of these sticks are made of wood. It can be observed that some of the earliest staves of DNF were made of wooden sticks, including epic poems of level 55. Just like Gandalf in the movie The Lord of the Rings, he is a very famous magician, and his walking stick is made of wood.

Generally speaking, the higher the mage level, the better the staff used, and the better the additional attributes or damage.
