Back Cran-door is an achievement that requires the player to open the hidden door in the Crandor and Karamja Dungeon.
It can only be opened from the Crandor side initially and as such requires Dragon Slayer to access it. It is located by the lesser demons on the Crandor side and the deadly red spiders on the Karamja side.
Completing this achievement also completes Cran Door's Secret.
