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.
Uncountable demons roam the Abyss, massing at its gates and clamoring to break through to despoil lands beyond. In groups, they attack without discipline but also without fear or pity.
