A magic tool 「魔導具 madōgu」 is an instrument that aids the use of magic.
Magic tools come in a variety of forms and serve myriad functions. Most require some amount of magic from the user to work, so those with little to no magic may be unable to use them properly. The most common types are brooms, which enable even the weakest mages to fly, and wands, which help mages focus their magic power.
Dark Magic Tools 「裏魔導具 Ura Madōgu, Viz: "Dark Magic Items"」 are a rare and dangerous type of magic tool. Their dramatic effects can come at the expense of the user's mana or life force.
