Seems like raising a rock drake 1st will help you tame these. 1st raise a drake. 2nd collect a bunch of rock drake eggs. 3rd find a basilisk and while riding the cloaked drake drop the eggs one by one and it will eat them.
If you are looking to get a basilisk on crystal isles don’t even try without forcetame or spawn rock drakes due to the drakes not spawning. Thanks for adding acid spitting snakes on the map TAHT CANT BE TAMED
Taming a Basilisk is simple. First you throw a light let on the ground, and place a metal foundation over it and switch the foundation to block form. Then drop all the eggs on top of the metal foundation and lure the basilisk to the foundation. It will focus on the bulldog, but cannot damage it.
