As in Harlan Ellison's short story How's the Night Life on Cissalda?.
The casting of this spell will cause an interdimensional connection between the world of the spell caster and the alternate world of the Cissaldans. The utterance of this spell attracts one Cissaldan which will come through the connection and attack whomever the spellcaster directs the spell against.
The recipient has an immediate desire to "do a disgusting thing with a disgusting thing" and will fall upon the Cissaldan with much vigour. The recipient will not be able to do or say anything else since his or her complete concentration is centred on the Cissaldan. The two will continue to copulate until the recipient dies of starvation. There is no known way of separating someone (or something since the Cissaldans do not discriminate in any way) from a Cissaldan until the recipient dies. After the death of the spell recipient, the Cissaldan will return to the world from which it came.
Cissaldans are described as having two penises, two vaginas, and are physically disgusting to look at. They, however, love to make love so to speak, and can physically adapt to any sexual physiology.
