Ritual of Holding
This is simply a way of extending the effect of another ritual. Use of this ritual adds six hours to another ritual in order to extend its duration or enhance its effect. Of course, this spell's results differ for every ritual to which it is added. Examples: It will lengthen the reach of Blood Walk to include the subject's progeny, and perhaps those whose blood he has tasted as well. It will cause the container of Engaging the Vessel of Transference to exchange only one Blood Point for two Points that it takes. It may render a ward virtually indestructible. It may make it impossible for Cleansing of the Flesh to eliminate the Shaft of Belated Quiescence. It may keep a spirit trapped by Raise the Dead indefinitely immured in the corpse. The caster can make suggestions as to how it should work, but the Storyteller is the final arbiter of the extent of the "holding."
Commentary: As an early example of metamagic, this ritual has merit. The six hour casting time and high difficulty makes up for its variable and flexible effect. While it would be better in most circumstances to use a metamagic ritual that is specifically tailored to the desired effect, Ritual of Holding will do in a pinch.
