BEAR trap does not work on him

USE DARTS, arrows will usually kill it before it knocks out

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!

Get on a rock or die

Try using soothing balm thats a good trick
