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.
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
