I figured out the trick. i just need stand still after peacemaking and it'll remain peace
Thanks for the information!
I got a question about taming hellhounds. I could peace hellcats and lava lizard. They'll stand still for 5 taming attempts. But hell hounds are similar to drake and dragon, they could only be peaced for few sec. is that normal or do I need higher peacemaking skill to stop the hellhound?
