I found a 150 Dire Bear (pure black), and knocking it out with crossbow & tranq arrows almost killed it. Left it with 300 health out of 2500 so my recommendation would be to use tranq darts & tranq arrows as a mixture and or just tranq darts if you have enough. Tips from yours truly.-Nova
Probably the most versatile land creature. Can eat berries and meat. Hard to tame unless you use DARTS or a SNOW OWL to heal it during tranq arrow-ing it with a x-bow.
Probably best to put HP>Dmg. These things are trucks but don't get to cocky.
Best utility mount after theri can gather meat and berries also this guy can get 1k weight and almost 900 melee with enough lvls I know this because my bear ( name is teddy the bear) is stronger than my 209 Rex
