To tame a lvl 100+ you cannot use tranq arrows as it'll die but still the torpor will not increase fully... you need a lot of tranq darts...say like 50 for a lvl 120 bear... need a soothing balm and some prime or raw meat... I will suggest to put 3 stone pillars on each other and add wooden ladders... lure the bear (or you can also make the structure near the bear, as it only agros if you go too close to it) and get on the pillars...start shooting...This part is easy, but the knockout part is tricky, cuz the bear will run when it's torpor is high and believe me it runs really fast, make sure you don't lose it and keep shooting tranq darts...also make sure you have already killed any carnos and terror birds around...

But all your hardwork will pay...

I have a lvl 200 bear and i wiped the entire population of redwood. :)
