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 if any attempt to cast spells.
