Magical Items
Imbuing items with magic
This is difficult and needs a compatible medium. There is no general answer as to how to do this. Magic items such as a magic sword or boots of speed are not typical. Magic could be a sharp sword, a potion, an ointment, a focus, etc. Magic items are not well suited to armies though some may assist in tactics. Items that allow the user to control a magical effect require the use ability skill.
