This perilous exercise in dweomercraeft summons up a powerful demon of type IV, V, or VI, depending upon the demon’s name being known to the magic-user. Note that this spell is not of sufficient power to bring a demon of greater power, and lesser sorts are not called as they have no known names. In any event, the spell caster must know the name of the type IV, V, or VI demon he or she is summoning. As the spell name implies, the demon so summoned is most angry and evilly disposed. The spell caster must be within a circle of protection (or a thaumaturgic triangle with protection from evil) and the demon confined within a pentagram (circled pentacle) if he or she is to avoid being slain or carried off by the summoned cacodemon. The summoned demon can be treated with as follows: 1) 2) The magic-user can require the monster to perform a desired course of action by force of threat and pain of a spiritwrack spell (q.v.), allowing freedom whenever the demon performs the full extent of the service, and forcing the demon to pledge word upon it. This is exceedingly dangerous, as a minor error in such a bargain will be seized upon by the monster to reverse the desired outcome or simply to kill and devour the summoner. Furthermore, the demon will bear great enmity for the magic-user forever after such forced obedience, so the spell caster had better be most powerful and capable. By tribute of fresh human blood and the promise of 1 or more human sacrifices, the summoner can bargain with the demon for willing service. Again, the spell caster is well advised to have ample protection and power to defend himself or herself, as the demon might decide the offer is insufficient — or it is easier to enjoy the summoner’s slow death — and decide not to accept the bargain as offered. Although the demon will have to abide by a pledge, as his name is known, he will have to hold only to the exact word of the arrangement, not to the spirit of the agreement. On the other hand, only highly evil magic-users are likely to attempt to strike such a bargain, and the summoned cacodemon might be favorably disposed towards such a character, especially if he or she is also chaotic. 3) The summoned demon can be the object of a trap the soul spell (q.v.). In this case, the magic-user will not speak with or bargain for the demon’s services, although the cacodemon might be eager to reach an accord with the dweomercraefter before he is forced into imprisonment. The trapping of the demon is risky only if proper precautions have not been taken, for failure to confine the monster usually means only that it is able fo escape to its own plane. Once trapped, the demon must remain imprisoned until the possessor of his object of confinement breaks it and frees him, and this requires one service from the now loosed monster. If the individual(s) freeing the demon fails to demand a service when the monster asks what is required of him, the demon is under no constraint not to slay the liberator(s) on the spot, but if a service is required, the creature must first do his best to perform it and then return to the Abyss. The duration of service of any demon must be limited unless the demon is willing to serve for an extended period. Any required course of action or service which effectively requires an inordinate period of time to perform, or is impossible to perform, is 50% likely to free the demon from his obligations and enable him to be unconstrained in his vengeance upon the spell caster if he or she is not thereafter continually protected, for a demon so freed can remain on the plane it was summoned to for as long as 666 days. The demon summoned will be exceptionally strong, i.e. 8 hit points per hit die. Casting time is 1 hour per type (numeric) of the demon to be summoned. If there is any interruption during this period, the spell fails. If there is an interruption while the cacodemon is summoned, it is 10% probable that it will be able to escape its boundaries and attack the magic-user, this percentage rising cumulatively each round of continued interruption. Each demon is entitled to a saving throw versus this summoning spell. If a score higher than the level of the magic-user summoning is rolled with 3d6 (2d10 with respect to type VI demons), that particular spell failed to bring the desired demon. When this occurs, it is certain that the named demon is imprisoned or destroyed or the name used was not perfectly correct, so the spell caster will have to call upon another name to bring forth a cacodemon. The components of this spell are 5 flaming black candles; a brazier of hot coals upon which must be burned sulphur, bat hairs, lard, soot, mercuric- nitric acid crystals, mandrake root, alcohol, and a piece of parchment with the demon’s name inscribed in runes inside a pentacle; and a dish of blood from some mammal (preferably a human, of course) placed inside the area where the cacodemon is to be held.
