They heal any tamed Dino nearby at the cost of food. Get a whole large pack of Daedons made up of pack leaders and you will be very well protected and since they can heal each other one of your daedons will rarely die. Upv0te if ya found helpful.
Idk if it was just mine, but I'm pretty sure their food goes down SUPER fast when tamed. Same goes for when being tamed. Mine died a day after I logged off due to starvation. Rip Bacon. He was so young...😢😢😢😢
It’s useful for healing, yes but it also eats a crap tonne of food to heal. I once had one and it ate multiple stacks of meat in a few minutes with healing on. Still helpful for breeding and raising tames.
