Who is The King in the Mists?

The King in the Mists lurks at the heart of the Crux of Nothingness, serving as the final challenge of this treacherous endgame dungeon. This boss isn't just about raw damage—it’s a battle of positioning, resource management, and adaptability. He employs a mix of:

• Corrosive Fog: A spreading chaos-damage mist that forces constant movement.

• Mistbound Wraiths: Summons that explode on death, dealing AoE chaos damage.

• The Memory Gate: A puzzle-based mechanic that locks access to the final phase.

• Honor System: A unique mechanic where dealing damage builds Honor, but taking damage drains it. If you max it out, the boss enrages.

Why fight him? Defeating him rewards Uncut Spirit Gems, Regal Orbs, and exclusive Ascendancy Class items, making it a must-farm encounter for min-maxers.
