Be warned!! I’ve seen 2-3 of these take on a Spino and kill it!

If you want the stuff from their dams...don't tame them cause they won't build any more dams! Like so everyone can see :D

Do not leave them unattended torpor drains quicker than you can run from a giga

Do not leave unattended the torpor goes down at a monsterous rate

The bad thing about these guys is that once tamed they cannot build any more dams

They love to share stuff from their dams. Go ahead and help yourself

Make sure no other Castoroides are around then bola it and shoot it with tranqs until it knocks out. Make sure you bring loads of bio toxin, because their torpor drains fast. I used this method and tamed one at level 42

Strong as hell, especially in packs. Don't put such nice things in your dam if you don't want me to raid it. Jerks.

The way to tame these guys is to run up to one of their dams and then open it and then immediately close it (you don’t have to take anything from it, opening the dam will immediately aggravate all and any nearby beavers). Once this step has been done, you must bola the beaver (assuming only one tries to fight). I actually made a hearty mistake and bolaed the first one that came whereas I should’ve killed the second first (I was making a video, the second one got killed). Once the beaver is bolaed and separated from its mates, go behind it where it can’t hit you and hit it with a bat until you knock it out, but before doing any of these either kill jellyfish for bio-toxin for torpor (the beaver’s torpor will drain quickly) or farm a bunch of narcoberries in preparation. These guys are herbivores so you should also farm other berries besides narcoberries, or gather from the nearby forests. Keep in mind that beavers EXTREMELY slow eaters when knocked out, so patience is your weapon here.

There is in fact a slot limit! All dinos have 300 slots available
