To tame this creature you need an Ichyosaurus, because nothing will attack you if you are riding it. It takes a while for it to to start the second feeding. Also, make sure you’re using the same food or the taming process will restart. A must-have to get biotoxin, because they are torpor immune. Will receive damage if you go to far down, but rapidly gains health at the surface. If playing on mobile, go to unofficial server called (Official) Pearl’s Legacy. -KingJadon08
Rare Flowers affect the Basilo (slightly inconsistently) allowing you to kite it into your own water pen for a super safe, even easier tame involving much less swimming about. Seems to require you to eat at least 2 flowers to trigger the aggro effect, and it loses aggro the second the effect ends.
I saw my first Whale in the bay of Herbivore Island, I was like, hey, it’s a whale, i don’t have any proper sea tames (I had a sarco but that doesnt count) so I got raw prime and fed it that, I ran out of raw prime, Omygod omygod. I used normal raw and the taming bar DIDN’T GO DOWN! So basically I skipped the sharks and Ichthys and went strait for the Basilosaurus. IT IS AWESOME! I highly recommend a whale and they are very common around herbivore island (heck, there’s a new one in the bay now)
Easiest way to get rid of their flock of mantas is use a barry to stun and kill them, they can also keep up with the basilosaurus, kill any sharks or other creatures easily and oxygen isn’t a stat on them
