Once Human Sunken Lord Kill: The Boss Down on Your Difficulty, With Top-Tier Drop Chances.

Why do Once Human players target the Sunken Lord specifically? Because this boss sits at the center of endgame gearing — its loot table includes chances at top-tier weapon blueprints, Gear Mods, and crafting materials like Electronic Parts that feed directly into stronger builds. Without those drops, progression stalls. But the fight itself punishes unprepared groups, and Hard Mode raises the stakes further. Players who want the kill and the loot chances without wiping repeatedly order the carry instead.

KingBoost's raiders take you through the Sunken Lord fight on your chosen difficulty, handling the encounter mechanics and clearing the boss so you walk away with the kill credit and the full loot roll. Hard Mode is available for characters at level 40+, and we confirm your character meets that requirement before starting. All other rewards gained during the boost stay on your account — nothing is withheld. We verify the active Once Human account requirement up front, confirm your chosen difficulty against your character's level, and track the run to completion.

YOU WILL GET

  • Sunken Lord boss defeated on your chosen difficulty
  • Chance to obtain top-tier weapon blueprints
  • Gear Mods, crafting materials like Electronic Parts, and more
  • All other rewards gained during the boost
