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.
Going for a lvl 70 on hard mode with crops? Get fkn ready. Torpor drains hella fast. Almost 200 bio toxins used already and taming is still at 15%. You use 25 bio toxins on this guy, get back to it in a minute cause torpor bar will be draining already.
This little rodent is one of the best harvesters. They can harvest plenty of wood and thatch, berries, etc.. they also have excellent weight. They have decent melee damage, and here is how to get your own.
1. Make the kibble on whatever device your on.
2. Find this very big beaver. They are found around rivers and build dams.
3. Knock it out with tranq darts
4. Feed the kibble and a bunch of berries (use bio toxin to keep unconscious)
5. If tamed, put the saddle on it and take it home.
6, extra information. Wild castorodies have a chance to have black pearls! But be careful, looking in their dam inventory makes them Argo.
I found a level 16 for my pursuit to tame one. 2 Galli kibble and 10 (probably overkill) did the trick, took 2-3 minutes. 2-3 tranq darts will knock it out easily, just wait a second or two inbetween shots. Best wood gatherer, do not listen to anyone else. Also I've heard it can be a mobile smithy.
I wasted almost all my tranq arrows (I had like 70) to knock out a really high level beaver and I died probably like 20 times but it was all worth it because now I got a really powerful tame that none of my other tames can even compare to
