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 have tamed dozens of these. Set timer for 4 mins 20 seconds. Use ravager. Soon as it eats first egg start timer, drop next egg at 4 min and repeat. Kite it safely but DO NOT lose aggro or you lose efficiency. Don’t even let it go underground. I got a 145 with 97% effiency using rav. Multiple helmets and stim on ur tame to keep awake. Force feed when basil eats egg.
Best way, rav with health, Stamina and bump a few on movement speed, place all your eggs out and have the basilisk chase you back and forth past the eggs, just keep duck an weaving past and cause your on a rav it won't deagro meaning top marks on taming effectiveness, remember duck and weave
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!
Approach with Drake so it doesn't aggro, surround in Stone Dinogateways to trap it. Kill a nearby creature and leave its corpse, aggro Basilisk by hopping off and remounting Drake, run away to de-aggro. Basi should aggro onto corpse we left. Toss eggs and tame, kill and leave a new corpse before the first expires, rinse and repeat as needed.
To perfect tame them just tame a low level dodo or bulbdog them kill it near the basilisk place a stone foundation on the corpse aggro the basilisk over to the foundation on a drake or any mount drop the required eggs to tame it on the foundation and watch the snake munch on stone till it's tame
Easiest way is to throw you glow pet on the ground then place a foundation on top of it then you throw down the eggs and lead the basilisk to the foundation and it will sit there trying to eat the glow pet and will eat the eggs in the process and tame very easily
