Wand

A Wand (ワンド, Wando) is what is used for focusing Magoi and magic attacks. Wand's are essential to Magicians, if they want to use their Magic, because without a wand, Magicians can't send orders to the Rukh properly, thus their Magic won't work properly.

When a wand is broken or damaged, it is still able to perform magic, but it is quite unstable and not even the Magician using it knows what will happen.
