Very easy to tame. They are just a bit slower than a human so you could just walk back and tranq. Run away once in a while because it does catch up while you are walking. Once your mammoth of choice is knocked just run away for 10 seconds and the rest will lose aggro. Mine just took down a low level alpha Rex and took about 1000 damage after I put 250 armour hat. It's got a good health pool anyways. It's better than the beaver in that it can defend itself and my base, it can hold much more wood. It also collects berries extremely well. Thatch is also not a problem with this. And on mobile it's water spray can knockback even a rex incase I gotta bail... Did I mention that it's faster than a rex? Only thing is that it doesn't get as much wood but in the Arctic there's plenty of wood. Just spend a few more minutes collecting wood is the solution...
Best way to tame is have a crossbow with butt load of tranq arrows walk backwards tranqing it as you go every now and then you need to turn around to get a bit further away. I know this works because i have three mammoths that i used this exact stratigy on
Playing on Genesis in the Arctic biome, and I built me a simple 3x3 trap out of stone foundations, stone stairs converted into ramps, and stone doorways. It might not want to get up the ramp, initially, and it's kinda slow, but it does hit hard, if you're just in fur. This one was lv90. Gonna try starve taming. But yeah, once it's in there, just keep popping it in the head with tranqs. It's big ol fat head sticks out above the trap, so you shouldn't have a problem with headshots. Hope this helps.
They aren't extremely fast and are easily outrun, so just shoot it with a crossbow using tranq arrows and turn around and runa. Few steps when it gets too close. ( may be best to take out any other mammoths before attempting to tame )
If you see one near a body of water get a aquatic animal and start shooting it with tranq arrows/darts while your in the water stay away from the land or the mammoth will try to attack you if your not on land then it won’t noticeonce it’s knocked feed it
On the raft build a 3x3 foundation with 3 walls high and a ramp going up into the raft. Go to the winter area youll find Mammoths there. Get it into the raft. Once in the raft shoot it with tranq arrows. Starve it and then feed. Kibble is 80times its food.
