Pretty easy to take out with tranq arrows and crossbow. A few shots should take him out if low level. Just be ready to kill some megaladons. (It only tames with fish meat) Scroll down to the baryonyx wiki to see where they are
This dinosaur is a very intricate but interesting dinosaur to get. I did find it near the shore line as it had seen me and wanted to eat me. However I had 5 tranq arrows which you can get at lvl 21. I shot all 5 and he fell to the ground. Very good dinosaur to tame especially in the water. It beats anything in the water even with its stun strike. I recommend using this dino to fight. I have one named Juju. One like equals One love for Juju
Now, for taming a Baryonyx, there are a few methods (ok only 2 ik):
METHOD 1: THE TRAP
The usual. However, there are a few modifications to this new trap. Here's what you'll need:
-1x Stone Foundation
-8x Stone Doorways
-2-3x Wooden Ramps
NOTE: I will include an extra option for this method, where wooden ramps are not needed.
Now that you have your trap built, lure the Baryonyx into the trap. Start shooting it through the gaps in the doorways until its knocked out. Put raw FISH meat (They do not eat Raw Meat or Prime Meat) in its inventory and wait for it to tame. Make sure to keep an eye on its torpor and feed it biotoxins/ narcotics if needed. However, you can also go and hunt for raw prime fish meat (No megalodon needed) if you have a sickle, where you can harvest prime fish meat from Sabertooth Salmon corpses. Wait a little while and boom! A new Baryonyx!
Now, with the second option:
You can use an Argentavis to pick up the Baryonyx and drop it into the trap, saving you some resources in that you do not need the wooden ramps. Repeat the taming process and boom! Your Baryonyx is ready!
METHOD 2: The Easy Method
The only thing you need for this method is the Bola. Find a Baryonyx (Usually found in swamps which are dangerous, but can spawn along rivers.), get it to aggro on you, and bola it while its running to you. You can try to club him but I would definitely tranq it down. Once its down, repeat the taming process mentioned above and name your new Baryonyx!
Now, onto the utilities of this creature:
Baryonyxes are great cave dinos, with decent health, melee, speed and stamina. Although there are better options for different caves, the Baryonyx is the most versatile and is great for most, if not all caves, this is due to their stats and also slender body, allowing it to fit through most slim cracks in caves. Do note that when force fed Raw Meat, the Baryonyx will not heal, but force feeding fish meat will. They also have a AoE ability that only works in water which does a tail spin attack, stunning nearby creatures (Not all of them) and doing damage (It works up to the Megalodon I believe.).
That's all I have to say about the Baryonyx. Thank you for sticking around and happy taming!
