I tamed a level 40 mammoth, no cheats/tame boost on settings. It ate 100 mejoberry (it said 250 on here) but I needed 102 because spoil times a bummer. It also took 7 narcotics not 76 like it said here. Unfortunately didn't pay attention to how many tranq arrows it took. Hope this helps :)
Build a raft with about 9 or so foundations/ ceiling and put Walls on the perimeter and ramps in the front and put large storage boxes along the walls and go to the swamp with a buddy and just sit on the mammoth on the front of the raft and swing away. Best wood/thatch/shroom farm ever
Tame on the outskirts of the winter biome close to the ocean, there’s more visibility and you only have to watch for threats from one direction. Helpful because these guys take a long time to tame and everything in the winter biome is aggressive to them!
Alrighty guys, here was my adventure with taming a Mammoth. Level 2 Mammoth took me 20 minutes to tame, no narcotics (though I took some just in case), and 135 Azulberries. It was super easy but the only thing I had a problem with was the Rexs. So Mammoths are easy tames but you gotta protect them with your life once they're knocked out.
Good for berries late game and or wood saddle is pretty cheap and is a all around good game upgrade its weight or health to tank turrets but a turtle is much better. It can be picked up by a quetzal so you can tame it at your base the attic isn't a very safe place to knock anything out.
I'd suggest kiting it to your base and tranq'n it with an anky or dino with high health that you can shoot off to make for an easy solo tame.Get that raptor kibble and bam you got yourself a snuffalufagus. Your welcome
