for those who doesn't understand ki, Imbuing or Fabricating i will eplain for you. Ki is a special energy that only impulse users has in some rare case a non impulse user has ki this is because of their family and some of these users can use it paragons doesn't have a ki but their yokai do. Imbuing or imbuement is when a impulse user coats apart of their body, someone or something else with ki then imbue their impulse with their ki.
