This beautiful creature has a ton of carry weight, spits like a poison wyvern, can burrow underground and move while you ride it, and can slither over small obstacles. I want one. Just look out for them in your college’s sewer system.
When it is underground it does use stamina which means it can not be underground permanently, it is extremely fast when it is underground and untargetable, and when underground it will be blocked by structures such as, walls, foundations, rocks, etc.
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.
Actually the Basilisk only eats Rock Drake fertilized eggs. The wiki says that it should also eat other fertilized eggs, but currently it ignore them. Probably it's a bug, for now feed it Rock Drake eggs
3 min 30 second feeding interval it seems. I have better taming effectiveness by keeping it aggroed while running it in circles. Lvl 20 only took 2 eggs. Lvl 85 took 4. Drop 1 egg. Aggro. Let it feed. Start stopwatch. When ready to feed it rears up n screams but does not spit
Get yourself a Rock Drake, Karkinos, Spinosaur or any other creature usually ignored by this creature, dismout to gain its attention and mount again; Drop the Rock Drake Egg from YOUR inventory and proceed to circle the Basilisk until it looses interest on you. Wait for the feeding interval to end, repeat.
I tamed my level 20 on 2x using 3 drake eggs. I strongly suggest using a trap. One behemoth gate and 5 dino gates did the trick for me. Just tossed the eggs down and went far enough away that it would drop aggro. Each egg gave abut 49.5% effectiveness. Good luck!
