With the recent Menaphos update to the game, corrupted creatures in the Sophanem slayer dungeon have been added. If you get assigned the slayer task "corrupted creatures," you can kill these for experience (or if you get a direct corrupted creature assignment obviously).
However, what if you are assigned the normal version of the task? For example, lets say I get assigned "Dust Devils." Does that mean I can only kill the regular ones for it to count towards the slayer task or can I also kill the Corrupted Dust Devils as well?
