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
With such a low breed timer and they're alternate swing being the same damage as a Rex they make ideal breeding and are great for meat runs very fast and have huge carry weights. A very good tame one of the best in my opinion
The most risk free and effective taming method is to
1. Build a taming pen
2. Lure or drop him in
3. Build a bed and storage chest next to it
4. Tranq the bear until he starts to show blood
5. Put your inventory in chest
6. Let the bear kill and eat you.
8. Respawn in bed, get inventory and finish tranqing. No need to switch to a bow or use traps.
This is very effective because the bear will regenerate a lot of health from eating you. And you will have no risk knocking it out. If you do this correct, maybe even kill yourself twice, you can get the bear to be at 80-100% health when you knock it out. Thus increasing chances of it surviving it someone/something hits it.
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!
Direbears are deadly when aggro'd so try to trap them in a ramp box. Use darts, as even an ascendant crossbow will porobably kill them. Great for carrying weight, crossing distances, and gathering fiber, meat, and berries.
Best way to tame these is to build a little 2x2 stone fence foundation square, a stone Dino gate at one end a stone doorway at the other and fill the rest with stone window frames. Lure it in the gateway, run our the doorway, tranq safely through the window frames
