Legends and Lore
With an Arcana or Religion check, characters can learn the following:
DC 10 Demons are fiends spawned from the Abyss. They are creatures of pure chaos: even the most intelligent demon can’t be reasoned with.
DC 15 Poison can’t adversely affect a demon’s alien physiology. They shrug off much of the damage caused by cold, fire, lightning, and mundane weapons.
DC 20 The most powerful demons are even more resilient. They entirely ignore the effects of many magic spells.
Balors are the most powerful demons in the Abyss, second only to the demon lords themselves. Standing twice as tall as a full-grown human, with tattered wings and a pair of wicked horns, balors inspire terror in all who see them. Even more fearsome, however, are the balor’s weapons. Each balor wields a lightning-bladed longsword and a whip formed from living flame, which it uses to smite its enemies and command obedience from lesser demons. A balor’s ever-burning rage manifests as a literal fire that its physical form can barely contain. These flames cause the balor’s skin to glow red-hot, and when a balor dies, its body explodes in a fiery conflagration.
