The Ringed City DLC introduces several optional areas and bosses that are not required to complete the main storyline of the DLC but offer significant rewards and lore. Accessing these often involves discovering hidden paths or fulfilling specific conditions.
Accessing the Demon Prince Boss Fight
The Demon Prince is a formidable optional boss that guards a significant item. To reach this boss, players must first navigate through the initial areas of The Dreg Heap. After defeating the Halflight, Spear of the Church (which can be invaded by other players or fought as an NPC), players will find themselves in a new area.
Following the main path from the Halflight encounter, you will eventually come to a large, open area with several demon-like enemies. The path forward leads to the final boss of the DLC. However, to access the Demon Prince, you need to deviate from this path.
Look for a specific archway or a break in the environment that leads to a separate, more secluded area. This area is often characterized by a distinct visual change, such as a different type of terrain or architecture. Carefully explore the periphery of the main path leading to the final boss. There will be a distinct path that leads downwards or into a more enclosed space.
This hidden path will eventually lead you to a boss arena. Be prepared for a challenging encounter, as the Demon Prince is a multi-phase boss that requires a solid understanding of its attack patterns and weaknesses. Defeating the Demon Prince will yield the Soul of the Demon Prince, which can be transposed into powerful weapons or spells.
Accessing Darkeater Midir
As detailed in the "Secret Path to Midir" section, this optional boss requires significant exploration off the main path. After reaching the Ringed City Streets bonfire, players must find a hidden ledge that leads down into a dark chasm. This path culminates in a long, descending bridge that leads to Midir's arena.
