While breeding this creature is not as difficult as others, There's an easier way to do it. When it is born I advise you feed it raw meat until it hits juvenile stage, after that point fill up troughs and the bears inventory with mixed berries, since this creature is an omnivore it can eat berries. Using berries until it is fully adult will ensure that it's food source does not spoil as quickly as raw meat can. Good Luck!
I was taking a level 44 dire bear, he was at 94% tamed and then a Thyloceo came out of nowhere and killed him, raptors and Carnos also don’t like dire bears, I would recommend bringing a Parasaurolophus once you knock out the bear do you can detect incoming enemies who may want to attack it
To make honey last practically forever, make a fishing rod and equip honey, that is about to spoil, to the fishing rod, then un-equip it. It should refresh the spoil timer. Does not work with leech blood. Tested on PS4.
Direbear have little health compared to torpor. Keep a few tamed dodos at your ramp trap. When you've shot the bear enough for it to be bloody, throw in a dodo. It will instantly kill and eat it and start regenerating health. Give it a moment or two and continue darting. Happy hunting!
