Djinn shake hands by folding their middle finger or their life line finger into their palm to protecay want to use their powers.
When djinn are disguised as objects such as walls or statues they must act like objects, that is to be seen and not heard.
Later, as he is collecting data, light reflections cause the gem to explode and the djinn is released.
These were ultimately replaced by a scene in which he discusses the djinn with a professor.
He tells them that they are djinn (genies).
It has also been shown that if a human injects djinn blood into their system they will suffer spontaneous combustion and be reduced to ash.
In that situation the "bissu" will permit an excellent djinn to seize them and to proceed as an emissary of the batin.
Djinn, based on each of the four classical elements, can be found scattered in hiding throughout the game and split between the characters.
