I recently received a starved ancient effigy from a cockatrice in the slayer cave. I didnt see the cockatrice listed as a potential creature to drop this item. Sooo I just wanted to let you guys know.

It is already on site they do:

Not in the tbale in the effigy guide but that table clearly states:

Visit our bestiary to find out what other monsters drop them as well!

 

aka the table does not by any means list EVERYTHING that drops them (which would be a heck of a table since a good 75% of monsters drop them)

As Sy has mentioned instead of creating a huge list of what drops them, we added them into the bestiary instead of each monster, So whatever task you may have you can simply check that monster in our bestiary. :shades:

 

Problem solved, the lock unfolds.
