If you’re looking for an easy tame, drop them and deaggro so it burys, that will make it easy. If you want a good one though, you need to avoid letting it bury. I use 8 stone gates in a octogon without doors and a 7 high pillar over the top with ceilings above the middle of the trap. Then you use climbing picks to get right above it, drop the eggs and wait. If it takes more than about 5 minutes to eat an egg or looses aggro music, go down outside the trap. MAKE SURE you have plenty of gas masks or you will die. Masks are better than hazard helmets because hazard breaks based off how many poison hits you, and a lot per poison ball, and gas mask just auto breaks really slowly. Gas mask is much cheaper.
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
