If they start to run after a first few shots stay where you are and stay on a rock or somewhere it can't get you it will deal massive damage I lost a lv 129 baryonyx to a level 50 run in a zig zag it gains speed faster it runs straight
Direbear has no pause time between hits. The attack has no push back on its end no matter the level. Just think of it as non-stop hit for hit if you're cornered. End result death. But can be avoided because Agro circle is very small (3 foot away from direbear will be its agro circle.) making it easy for a head start run in case you try to tame.
Unless you have a very powerful character/mount, I would suggest to keep a good distance away from these magnificent beasts. They have a surprisingly small aggro range, but their melee damage is IMMENSE, and can kill even high level mounts with relative ease. It is honestly best to just leave them alone, as they don't even give that many resources when you harvest them, and you can easily lose an extremely valuable tame. Take it from me: I've lost two amazing wolves to these beasts, once from inexperience, once from being unable to escape due to having no stamina.
