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!
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.
