The Basilisk is tamed by dropping fertilized Rock Drake eggs from your own inventory and luring it to each egg while preventing it from burrowing or losing aggro. It serves as a powerful hauler with strong mobility, decent swimming ability, resource weight reductions, underground travel, and a venomous attack that deals damage and induces torpor, though burrowing can be hindered by stamina, oxygen, falls, and terrain. When encountering one, avoid its ambushes and warning signs; escape with a fast mount through obstacles or uphill terrain, or use a strong group at range while avoiding its poison.
