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.
To reduce chance of killing it while trying to knock it out is by shooting with a primitive crossbow without delay until it starts to show blood then switch to a regular bow and then space shots 7 seconds apart - works every time for me no matter the level
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.
Bears make an excellent mount for exploring caves. If you can get about 3 high level ones you and other tribemates can explore through most caves with ease. And if you were to get in trouble these bears can run at high speeds so you can escape most predators.
