You can animate statues of creatures, humans, or animals. Their abilities are based on the creature the statue was based on. No matter what their durability is that of the material they're formed from. A wooden statue of a Phoenix will still be weak to fire due to the material it's made of. Strength also increases with the size of the statue and how detailed it looks. A metal statue of a dragon the size of Lady Liberty could go toe to toe with any of the Endbringers.
