If Dreams Could Kill
This expansion adds new options for developing characters in a modern noir setting where ordinary people confront supernatural forces. It introduces six themebooks, a character concept guide with archetype and trope tables, and 50 veteran improvements covering Mist awareness, Mythos abilities, deduction, conflict resolution, and cinematic feats. Twenty-four ready-to-use Relic and Familiar theme kits provide additional power sets that can be added as extra themes.
