The Citadel of Heights and Depths (or CoHaD for short) is a Challenging difficulty Citadel in Ring 3 by Jukereise, ciel_azulsky, Gammattor, burgchin and punkynil. This citadel was planned to be in

Zone 3 as a tower rather than a citadel, but the Tower of Menacing Creations was finished before CoHaD was, and it was placed in instead of CoHaD. The main gimmick of this citadel is that there are many pits throughout it leading into basement floors.
