From publisher blurb:
Journal of Dread Book 1: Secrets of the Oozes adds many new elements to creatures players may have previously encountered and thought familiar or predictable. This journal brings a new sense of fear and respect to the creatures presented herein to your game.
The Journal of Dread series offers new options for players and gamemasters alike. In mechanical terms, it provides new game material for ooze-themed items, weapons, spells, and a host of new ooze creatures ready to command a new level of respect from your players.
While the concepts presented in this tome serve to expand previously established rules, this book also offers a new system that can be applied to standard hazards. Called living hazards and loaded with ready-to-play examples, this system enables you to create brand-new hazards for your campaign world.
