Fallout 4 Creatures

General information
Creatures are monsters and humans encountered in The Commonwealth and surrounding areas, for machines and robots, see Fallout 4 robots and computers

Legendary enemies
Most creature types have a chance to spawn as a Legendary variant, as well as tiered named variants leading up to the Legendary creature. A legendary creature will always drop weapons or armor with unique modifiers (displayed on the Pip Boy with a star), for more information on these modification see Legendary effects. Sometimes different weapons with the same unique modifier as another weapon can be found, though this doesn't happen often.

The chance of a creature spawning as Legendary varies based on difficulty. The default difficulty is Normal.
