To tame a bary can be easy and hard because if you are taming on panda will make it easier for you to tame it but in water I recommend tame it on land. Use bolas and tranq arrows or a wooden club to knock it out. If you get it raw meat to tame it won't work. So tame it with the preferred kibble or raw fish or cooked fish.
So here's a sad story for you all. I bred my two barys (I had recently tamed a female for breeding but planning to kill afterwards for more tame room). It went great until I hatched TRIPLETS. I was in awe and joy when I saw this but instantly got sad afterwards. I had to kill two of them... this hurted me a lot, even if it was just a video game. They all had the same stats so I killed the ones where the imprinting are much easier. I got around 30 prime meat from them. THIRTY. The baby barys will forever be in my heart... always.
Easy to tame and very good for a starter tame. Simply bola it and hit it with a club. Be advised if it’s a high level it might break out of bola. These guys need fish meat, they’re picky. Totally worth taming can probably take out a trike, my two level twenties killed four trikes in one go, and I was playing on normal.
