Armordillos are creatures found in Crater Rim. They deal slash/beat damage and soak it as well. They are tougher than most other Crater Rim creatures and hit rather fast. Juicers will attack you if you are attacking an armordillo in the same room as them. You can be paid for killing them through the Rim Hunter contract.
Armordillo armor is a fairly good craftable armor that soaks lots of beat damage.
