Survival Mode Debuffs Guide – Ailments, Statuses & Cures

Survival Mode adds new status effects that will debuff the Lone Survival. Below you’ll find a list of status ailment types, how they debuff your character, and how to cure the problem.

Note: ALL debuffs reduce max AP.


Unique Survival Buffs / Debuffs:

These are unique buffs & debuffs only found in Survival Mode.

  • Dark Craving: Must eat human flesh. Cannot cure hunger with any other type of food. Caused by the Cannibal perk.
  • Well Rested: +2 END, +2 AGL, +10% XP (Limited Time) — gained from sleeping in player-owned bed.

Sickness / Ailment Debuffs:

How to Cure: Craft Antibiotics from a Chemist Station + [Chemist Rank 1]. Requires: Acid (2), Purified Water (2), Stimpak (3), Glowing Fungus (3) — Found in First Aid / Yellow Chem Boxes. Sold by vendors.

  • Fatigue: Require more sleep to avoid exhaustion debuffs. [Note: Cure with 12 hours sleep.]
  • Weakness: Take +20% more damage.

Sicknesses are random ailments that are more likely to occur if your immune sickness is weak. Using chems, eating uncooked meat, drinking irradiated water, and taking damage from ghouls or bugs — all increase your chances of contracting an ailment.
