The Monstrous basilisk is a superior variant of the Basilisk. It has a chance of spawning once after purchasing the unlock Bigger and Badder for 150 Slayer reward points from any Slayer master.
Similar to their lower-level counterparts, a mirror shield or V's shield is required to safely engage them, as otherwise the player will take rapid damage and have their stats drained.
In addition to 100% drops and tertiary drops, superior slayer monsters will always roll 3 additional items, of which only 1 roll may be from the superior unique table. The other rolls are performed on the regular counterpart's table; their displayed drop chances represent a single roll.
Drop rates estimated based on 48,470 kills from the Old School RuneScape Wiki drop log project, unless otherwise cited.

- The monster's examine text is a reference to the Harry Potter series, in which phoenix tears are one of the only cures for a basilisk's powerful venom. However, basilisks in RuneScape aren't poisonous.
