Fallout 4 Creatures

General information
Creatures include animals, humans and their mutated counterparts encountered in the Commonwealth and surrounding areas.

Legendary creatures
 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 almost always drop a weapon or armor piece with unique modifiers (displayed on the Pip Boy with a star). For more information on these modifications, see Legendary effects.

In combat, legendary creatures are very powerful as they are stronger than their non-legendary counterpart (see below for specific differences). They are often among the highest-leveled variants a player is capable of running into at their particular level. For example, a level 30 player seems more likely to encounter a legendary super mutant brute (approx. level 22) than a legendary super mutant (approx. level 10), but the lower-level encounter is still possible.

If the damage from a weapon is not enough to kill a legendary enemy and they survive a hit with less than 50% of their health remaining, they will mutate. This cause them to start regaining all health and grow stronger. A mutated legendary enemy gains a glowing aura to show that it has mutated.

Spawn chance table
