Fuccubus

In its natural form, a fuccubus looks similar to a tiefling, albeit with wings, long talon-like nails, and eyes with black or red sclerae. When it senses potential victims are nearby, it transforms into an alluring humanoid who is visually indistinguishable from an ordinary person.   The classification of "fuccubus" is relatively new, coming into popularity within the last century. A fuccubus in a male form was traditionally called an incubus, while one in a female form was called a succubus. Frekhologists have recently discovered that both have identical arcane footprints and are capable of shapeshifting into forms of any gender at will.

Fuccubi are capable of impregnating any humanoid who is usually capable of bearing children. The effects of this pregnancy on both mother and child are difficult to predict. The best-case scenario for the mother is bearing a tiefling child; these tieflings often have a stronger-than-average affinity for magic, but are otherwise ordinary tieflings. Other pregnancies may appear to bear a tiefling child who turns out cruel and anti-social and whose looks particularly favor their fiendish parent—this is a cambion, who will inevitably flee to the allegiance of the Nine Hells before their thirteenth birthday. In the worst cases, the pregnancy ends in the person weakening steadily until they collapse in on themselves and implode, releasing a flurry of imps from their corpse.   A few rare instances exist of a fuccubus impregnating a humanoid who does not have a womb. These "pregnancies" always end in the implosion and death of the mortal.

Fuccubi possess fairly strong natural telepathy for their rank. They are able to pick up on subconscious mental energy from nearby mortals and use it to predict what form will make them most attractive to the most possible victims. (This is usually effective, though difficult to target specifically when in large crowds.) Once they have attracted the attention of a potential victim, they use a combination of ordinary persuasion and charm magic to try to seduce them. A fuccubus can only charm one person at a time, but they can communicate telepathically with this person for as long as the charm effect lasts, even across planes.
