Sacriffice to Nightmare
Kiasyd who know their connection to the Abyss also know it's necessary to keep the entities within content, and doing so occasionally requires a sacrifice. Pragmatic Weirdlings reason "If we need to sacrifice lives, why not the lives of those we hate?" After painting the interior walls of a pitch-black chamber with fae sigils, the Kiasyd seals a sacrifice inside the room. Within seconds, the tentacles and snapping jaws of the Abyss reach through, and consume whatever offering has been provided. Those schooled in Abyss Mysticism believe the nightmare entity to be a part of the summoner, as it ceases to exist if it leaves the chamber emblazoned with the Kiasyd's sigils and blood.
Sacrifices who survive over a minute in the chamber are supposedly given the honored treatment of being diablerized by Kiasyd without, but Weirdlings sniff at such vulgar claims.
System: The vampire must inscribe a Chanjelin Ward (V20, p. 455) within a room, where it has the same effects as usual. The Kiasyd must then spend two blood points to summon a tangible nightmare from the Abyss before exiting the room, leaving her sacrifice behind. The nightmare is a tentacled, many mawed creature, which cannot exist outside the sacrificial chamber for longer than a single minute.
Kiasyd must have one dot Obtenebration if he want learn this ritual he may use this ritual without having a changing ward, but this will require blood point for each sigil
