U should use biotoxin if available to tame castroids because biotoxin is much better then narcotics biotoxin can be acquired from those jellyfishes near the beach.

Very deadly be careful they can destroy you just like me and kill triceratops

Definitely tame one of these if you need more wood. There pretty easy too tame just make a basic trap and lead this guy right into it. It’ll take a couple arrows but once it’s knocked out give it crops, mojos with this guys take soooo long.

I knocked one out and went out to gather berries to feed it, by the time I came back it already woke up

They are the best supplier of cement, and the best thing is that they like to share

Bring at least 5 stacks of narcotics no matter the level. The torpor drop is absolutely ridiculous on this thing.

This thing is INSANE to tame! After reading through the kibble and taming stats, I knew that the only way I could only tame it (I was on a busy schedule and was not advanced enough for this tame) was with a 15x taming boost. Even with the boost and a load of narcs (56) I nearly lost my tame and watsted an 15x taming boost. BEWARE OF THIS, ITS INSANITY TO TAME IT

A wooden bat dose nothing on a castoroides and the slingshot KO’s it

Narcoberries will make torpor go up and stay up when you use an over abundant amount. Use 20 and it will hit the top of the gage, go down, then go back up till the affect from the supplied berries wears off.

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

Dododex is wrong! They actually CAN be carried by an argentavis!

They torpor is very fast they won't be sleep for long so if u want to starve tame any animal kill a few jellyfish if you have the dolphin tame use them to kill jelly fish they harvest more bio toxin if not u can just use a spear to kill jellyfish and then take their bio toxin to my knowledge bio toxin is the most effective narcotic and it is easy to get and u get alot so feed this to any animal u want to starve tame unlike narco berries it won't give them food make sure ur sleeping beast has no type of food in its inventory only bio toxin wait for some time and keep feeding it to them until there food stats are close to zero and finally give them some food they will be so hungry they will tame in seconds if this wasn't helpful go online and search how to starve tame I really recommend u do so this a great skill to have like so not only noobs but every can see I play on mobile I have starved tame my two raptors name blue and delta(Jurassic world) they tamed in seconds also tamed my argy very easily with starve taming

They wake up fast my woke up In a sec

I also forgot to mention to use soothing balm. It will help you so much!

Can be carried by argys, so drop in a pen and nail it with arrows near your base

Insane torpor drain, make sure you have all the narcotics you need first even with low levels. Took of for a maybe 2 mintues becuase i was low on narco berries to make narcotics, came back when before making more to check up on him only to find he was walking aeound the pen as if nothing had happened.......

How to tame :

-Go with a tanky ride (trike, or stego), to a dam

-take anything you'd want from it, and mount back your ride asap

-all near beaver would agro your ride, so you'd just have to tranq them

-feed them with few berries, and tonnes of biotoxines & narcotics

Same interest or thery' but a bit easier to tame & breed

Just tamed the lvl 70 one at mobile single player, hard difficulty. With Rockaroots. Took me around 700 narcoberries, 180 narcotics, and 400 bio toxins. This guy's torpor bar drains SUPER fast.

So, I live in the footpaw and I've learned that to get these you either need to go through the titanoboa in the writhing swamps, or the spinos at the end of the beach. Choose one, I recommend the spinos because you can knock them out by standing at the top of the cliff above the beach and shooting them full of tranq arrows.

When you go to tame be care for the turber goes down coeckly get nrcotacs first
