Type and Subtype

Type and Subtype are a type of classification in Megami Ibunroku Persona.

A Persona or Demon's type and subtype determine its strenghts and weaknesses. As both Types and Subtypes come in pairs, the Persona or Demon will somewhat resist their Type and Subtype (resisting, absorbing, nullifyng or repelling it) and be weak to their Type's opposite. For example, the Demon Ganesha is of the Wind Subtype, meaning it resists it somehow (in Ganesha's case, by repelling it) and of the Element Type, meaning it is weak to Force attacks. Also, Types and Subtypes also determine the spells that a Persona can inherit via fusion: Personas of the Element and Force types cannot inherit spells that oppose their Subtype; Personas of the Light Type cannot inherit spells of the Death Subtype and Personas of the Dark Type cannot inherit spells of the Expel Subtype.
