Threats From Beyond

This bestiary presents a collection of outsider creatures drawn from across the planes, covering a range of challenge ratings and encounter roles. The creatures can support adventures involving devils and demons, as well as stories centered on strange planar beings with motives that are not always evil. Some entries are suited to direct combat, while others create danger through their presence, behavior, or unusual abilities. The collection provides alien foes and complications for campaigns that move beyond familiar bandits, dragons, and other worldly threats.
