Heroes must have upgraded armor and be in your party to be displayed in this monument.
If you enter the hall with a level 20 animal companion, you can display a generic pet statue at this monument, which features a bear, a Lynx, and a wolf.
In addition, you can display statues for three other animals (if you bring them individually to the hall), each of which counts towards the Any Rare Pet Statue requirement for the rewards calculator.
Black Moa
Black Widow
Phoenix
*Pets must be level 20 and be evolved to at least tier 6, before they can be displayed.
*You cannot display pets of your heroes
*Once a hero statue has been added to the Hall of Monuments that hero cannot be added again, even if different hero armor is obtained.
