The first deathclaws were created by druid circles as a guardian of deserts and other arid regions. Made by combining the traits of various animals no longer remembered, although some scholars believe a large amount was of a chameleon, deathclaws were made to defend the groves of druids and the ecosystem in the land.
Deathclaws normally prefer to live on their own and hunt any type of large animals they can find, their diets do change depending on where they live. Usually they hunt down large cattle like aurochs and deer, but some have been documented eating a more varied diet with large insects, bears, dinosaurs, and some packs have been known as becoming maneaters, although these are very rare.
Deathclaws can be domesticated by some brave and foolhardy beings. Druid circles will put them to work as the same grove guardians they were made for. Lizardfolk have been known to tame them to use as massive beasts of war to send into battle. Blue dragons will even keep them around in their lairs as guardian beasts while the dragon is away.
