The Halls of Agony is a three-level dungeon in Act I of Diablo III. It can be found directly below Leoric's Manor. King Leoric had many people tortured in these halls as he descended into madness before his death, and they have now been commandeered by the Coven for the horrific rituals they use to summon demons and fuel their magic. The player has to travel through these halls to stop Maghda and save The Stranger. This area must be explored in order to complete the achievement There Will Definitely Be Blood.
