A succubus has been summoned from hell to our realm by a fool using an ancient text called "demonic pacts for dummies". The ritual goes horribly wrong due to incorrect information and resulted in the summoner's death. The succubus is now free to roam our realm unsupervised and begins terrorizing the populace by leaving a string of bodies in her wake. A succubus has a number of advantages over a human, including increased strength, speed, resistance to harm, and telepathic powers. It has the ability to hypnotize its victims, putting them into a deep trance. A pleasant, euphoric haze descends on the victim who is under her spell, making them very open to suggestion. This ability only works on men, and uses a large amount of energy (mana) from a succubus to use. The creature can also use polymorphization to slightly adjust and tweak its features, changing its appearance as needed, but always in the form of a human woman. It needs to hunt to recharge its mana reserves, or it will waste away and become weaker.
The creature feeds by preying on humans that it seduces. It absorbs the mana from their souls, leaving them desiccated, dried up husks that are later disposed off. Sex with a succubus is far more enjoyable than with a mortal human, which it uses to release the energy from the victim. After the soul is eaten, the creature gains the memories and abilities of the person. The strength of its abilities continues to grow as it feeds off of more prey. At some point, it can completely "dominate" its victims, enslaving them to its will. A human under its spell at that point would do anything they are told to do by her, including murder, steal, or die. Hypnotization only works on one person at a time while the succubus is weak. As it grows in strength, it can extend it to multiple victims, but can use up its mana more quickly.
I'm trying to stay away from the sexy, fetishized interpretation of this creature, such as in the show "Lost Girl", and return it to its roots as a dangerous predator with the pathology of a serial killer. Based on these parameters, can the succubus survive long term in a modern setting, feeding on its food source, without bringing too much attention to itself?
