The cockathrice is a superior variant of the cockatrice. It has a chance of spawning once the Bigger and Badder unlock has been purchased for 150 Slayer reward points from any Slayer master. Like the cockatrice, a mirror shield needs to be equipped in order to fight it. It can also be safespotted with Ranged or Magic like the regular cockatrices.
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 63,641 kills from the Old School RuneScape Wiki drop log project, unless otherwise cited.
