[@BeautyoftheDark] Ok so; - For demons the feeling is like gaining a lot of energy at once. So imagine it as if you've drank a load of energy drinks at once and the effects immediately take effect. feeding can take from a few seconds to 30 mins; it depends on how fast the demon consumes the energy ( they can savour it or just gobble it up). - 2 meter radius from the human; the closer they are the easier it is to feed. - the human will be able to sense their energy being drained as they will begin to stop feeling the emotion that they have been fed upon for and they will become physically more tired.
