This creature is so easy to tame. All you need is:
1. An Ichthyosaurus(these guy won't be attack by any water creature, except the jellyfish)
2. Anykind of meat(I suggest using prime meat and don't use fish meat)
3. Find one of these creature
4. Feed it prime meat(It's a long time between the 1st and the 2nd feed, after the 2nd feed it's fast)
And then you get one of these, just be careful of the megalodons, they will attack right after it is tamed. I hope this is useful for you<3
So I was feeding it with the mantas still alive, that ended up with a couple of inactive specimen implants. When I finally got it, The mantas ended up killing the damned basilo. So, don't keep the manta's alive.
Tame a baryonyx and move close to a basilo with mantas around it. Don't attack but let them aggro on you move away from basilo and tail stun/attack mantas till they are gone. Feed prime meat or mutton and wait forever for second feeding. Once it is hungry again it is only a few seconds between the remaining feedings but it can be 15 minutes between 1st and 2nd.
So the flaws of breeding baby Vasilis
They need meat constantly and for some reason they loose stamina for no reason.
After fully grown it will slowly start to fill up and then you can start your new powerful basilo journey
I don’t know what everyone else did but In my experience the Icythaurus or whatever the dolphin is called, still gets attacked. Everything is chasing me on it. Sure I can out run everything but the tips here made it sound like you would get ignored.
Also, someone said you could tame it from the saddle you can’t you have to dismount.
Now this is all PS4.
So best bet is to have 2 - 3 people 1 to feed and the others to agro and lure away the mantas and megs.
Icys are fastest in my experience. So best bet to bait away and dart in and out.
