Who remembers this modern manual from about a year after Mastering Witchcraft hit? For me this was to 'high magic' and formal ceremonial what MW was to spellcraft. Both copies in my local libraries are reference-only, so I"m waiting for a used copy to arrive. I recall it as a fine example of how to build a high magic practice out of the mass of lore.
