I had tamed a level 145 direbear using raw prime and raw meat. It went up to a 196 after taming. It was killing everything It came up against, except for gigas and all alphas that were level 50+. Really good killing machine.
Faster than a giga, strong as a rex, with some levels can get to 1k carry, can gather and eat both berries and meat,can even gather fiber, if you tame a high level one you have a super gathering and combat mount. Unmatched in utility.
A high level can easily take down Alpha Carno's. It's perfect for taming other animals since it can collect both berries and prime meat. It can go through the central cave and is a highly speedy mount with good carry weight. It's also cuddly.
