You need to tame these kids on the island especially, these are like the BEST for killing cnidaria, and they are pretty easy to tame if you do it right.

Step 1: craft a raft and go float over the basil

Step 2: watch the basil and when it surfaces (or goes near enough for u to get out in time to escape mantas and drowning) feed it some meat DO NOT FEED FISH meat is much more effective

Step 3: open your inventory and click on the taming thing (idk what it’s called) and make it so u can watch the basil from afar.

Step 4: Wait for it to surface (now much easier to do)

Step 5: Rinse and repeat

Please do the suicide tame strat because I almost lost all my flak armor to mantas only bring ur meat and a raft. I tamed a level 60 Basil that was so far out into the ocean using this method.

Up so the noobs can see :D

Steelslaughter here,

Perhaps the most versatile, combat oriented, tankiest, and easiest water tames, I’ve converted two basilo’s into near-invincible war machines I can only describe as ARK’s equivalents of an underwater John-117. I, no joke, led 20 or so megalodons to one and all of them were shredded in under a minute. Also they produce oil, which is nice, but it spoils, so I usually solve the oil situation with my dunkleosteus. Very well rounded and a PASSIVE tame, would certainly recommend!

Peace out,

The thing with these archaeocetes is that they do not spawn at shallow waters yet not very deep either. And to make things worse, they can attract harems of hostile manta rays and ichthyosaurs to "feed on its leftovers" as mentioned in the dossier

Overall, make sure to bring one of your powerful water mounts to the spot, as you'll have to fight those off

They provide shock and temperature resistance, yet take damage at certain altitudes below the water

An amazing badass dinosaur. When I was bringing this dude back to my base, I kept getting swarmed by mega’s. My bailo kept pulling me out of tough situations and easily could take on four megas at once. Just make sure to buff up its health as it takes awhile to even damage this dude. Literally, my favorite dinosaur. I’d pick bailo’s over mega’s any day.

When taming, make sure you kill all the mantas as they are a pain in the ass when your trying to tame the bailo. I got lucky and found my bailo stuck on a rock in shallow water, allowing me to kill all the mantas. I’d recommend a sarco or itchy for keeping up with the bailo as you try and tame it. Make sure to get the mantas to follow you out of the water and where the water is shallow enough for you to stand. Pikes are could for killing these mantas, just hold the attack bar down as they circle you, don’t let up or your dead. Stay near the shore when taming. Be patient and wait for the bailo to come to you when trying to find. :)
