How to Cure Diseases and Remove Quirks in Darkest Dungeon

Updated 21 Oct 2026 Source Darkest Dungeon in-game mechanics and community documentation, retrieved 21 October 2026 By

Diseases and bad quirks quietly ruin heroes until they die. Curing them is cheaper than replacing the hero.

Why this matters

A hero with an uncured disease is a liability in every fight. The Sanitarium fixes what stress caused.

Step-by-step

  1. Check every hero for diseases after a run.
  2. Send diseased heroes to the Sanitarium immediately.
  3. Lock good quirks so stress cannot strip them.
  4. Remove bad quirks that hurt the hero’s role.
  5. Cure before the disease spreads through the roster.
  6. Prioritize front-line heroes for treatment.
  7. Keep Sanitarium slots full between runs.

Tips

  • Lock good quirks first
  • Cure diseases early, not late
  • Bad quirks compound into deaths
  • The Sanitarium pays for itself

Common mistakes

  • Ignoring diseases until heroes die
  • Losing good quirks to stress
  • Leaving slots empty
  • Curing only when it blocks a run

Practical notes

The Sanitarium removes negative quirks and diseases for gold and heirlooms. Prioritize quirks that hurt combat, not flavor ones. Cure diseases early, since they stack across a run. A clean hero performs better than a treated one. Remove the quirk that ruins a hero’s kit before the flavor ones. A fixed hero performs.

The Sanitarium removes negative quirks and cures diseases for gold and heirlooms, so prioritize the quirk that ruins a hero’s kit before the flavor ones. Remove the quirk that forces bad combat choices first, since a fixed hero performs far better than a merely cured one who still makes poor decisions.
