I like to use mine in tandem with my pack of megalodons for hunting squid, especially alphas.
I ride my basi and get the squid to focus on me while my sharks swarm it. Combined with my Basi's high health and melee, it usually makes short work of them (and most everything else, really).
More Basilosaurus Utility Tips
Reasons to tame a basilo:
1. Water tanks. They can take damage and dish it back out. I killed a moss with mine.
2. Fast health regeneration near surface. Fight any surface predator and barely lose any health
3. Makes oil.
4. Keeps you warm in cold places and cool in warm ones
If you don’t have a basilo, tame a basilo.
King of the sea. A tuso or mosa will do more damage but you can not be knocked off a basil making them essential for underwater caves which are full of jellies, Eels and even tuso's. They are also the perfect size to navigate through them without getting stuck or having to dismount. If you have a Baryonyx they are very easy tames, just use the AoE spin attack to kill all the Manta's and you can passively tame it at your leisure. Combine their oil with organic poly and water in a cooker to make soap which doesn't expire and can be ground back into oil and organic poly when you need it.
