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
