These things are very easy to knock out. Just bola it and then use tranq darts to knock it out, tranq arrows work too. WARNING! They eat Rare mushrooms and/or Plant Species X seeds so gather up a bunch and you'll be set.
I come on here for tips about taming and ko and all i see is complaining about changes made. Can i get some actual tips on catching this thing, tried bear traps but couldnt get it armed in time to catch one.
