Soth's Accursed Journal is BookBrewGames' (Matthias Gildemyn & Jan Sempels) ambitious debut work and the result of almost three years of work, expanding on the D&D 5e core rulebooks and supplements.
This sourcebook is a trove of hidden knowledge, gathered by Lord Soth himself during his many years as ruler of Sithicus. Stolen by his treasonous Seneschal, Azrael the Werebadger, it has seen many owners, all of them pursued by Lord Soth and his many enemies in order to retrieve this valuable collection of secrets. Featuring commentary by both Lord Soth and Azrael, it details several new character options designed for - but not limited to - the Ravenloft setting, such as new subclasses, new spells, new feats, new magic items, 3 new classes (The Death Knight, The Elementalist, and The Monstral), and more!
