That approach will definitely help out when generating random grimoires or mad science contraptions – no more rerolling when a specific transformation doesn’t match the theme.

Thank you! Right now I’m revamping the Preternatural Effects for the future revision of Ghastly Affair. In fact, the Bogeyman is a side-project necessitated by one of the new Preternatural Effects – “Inflict a Monstrous Curse”. This new Effect combines the old “Create Werewolf” and “Create Vampyre” Effects, and also allows the User to condemn a deserving target (or even themselves) to become a Beast Man, a Dragon, a Restless Specter (from the Ghastly Companion to Gothic Icons) – or a Bogeyman.
