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.
Drops
Cockathrice give 3 rolls on their regular counterpart's drop table.
