Abyssal
This bestiary presents thirteen mythic creatures from the Abyss, including ancient qlippoth, demodands, demons, planar predators, and other corrupted monstrosities. Each creature includes a complete stat block and unique mythic abilities, with challenges ranging from CR 3 to 23. The book also includes an introduction to the Abyss and its warring fiendish races, along with runestone rituals for binding the featured qlippoth. The creatures are designed for use with mythic rules and include threats such as the demon-devouring ylrygoi qlippoth.
