The optional Darklurker secret Boss is found in the Dark Chasm Of Old, past a series of extremely challenging enemies. To enter the Dark Chasm Of Old and fight the Darklurker, you must join the "Pilgrims Of Dark" covenant and reach Rank 2. Complete the listed requirements under the "Joining covenants and rewards" information below. Once you have opened the gate to the Dark Chasm Of Old, you need to reach and defeat a series of enemies in three sections in the area. Defeat the enemies in each section, and light the sconce at the end with your torch. Light all three braziers and speak with Grandahl to activate the elevator leading to the Darklurker. Note: If you die in the Abyss, you must offer a Human Effigy to Grandahl to re-open the portal. When you are Rank 2 in the covenant, the elevator inside the Dark Chasm Of Old will activate. Travel through the Drangleic Castle portal to reach it.
