Honestly don't use the bury feature while you are riding it. To use it press the jump button while riding it. The ability is cool and it makes you untargetable but if you are anywhere near water it will likely glitch and send you and your basilisk through the map and kill you both. I lost a level 100 in the upper mushroom One because of this. The Basilisk is fast enough and tabky enough to run away from anything without using the bury ability anyway. Thumb up so others don't lose one too.
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.
The Basilisk has weight reduction on stone down to 12.5 weight units per stack. I tamed a 150 and then dumped all points into weight. Now I have a 10,000 weight basilisk that I can slot cap with stone. I don’t even use Argies anymore for stone around my base, especially when feeding element dust gatchas. I’d rather have a slot cap than fly.
The Basilisk can deal torpor damage. It deals 3x your Basilisk's melee damage over 10 seconds. A 500% melee Basilisk will deal 1500 torpor damage over 10 seconds. Bite once every 10 seconds to make full use of this. Take into consideration a wild dino's natural torpor depletion rate.
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.
