Heavy metal poisoning
Natural water and snow on Sakhal, and water from hot springs.
Heals by itself
Early & middle
Once your stomach is clean: ~20 min per stage, ~3 min with a strong immune system.
Severe stage
Never alone
From 400 agents only chelating tablets help.
Cure
Chelating tablets
2 tablets from the peak.
Boiling
Useless
Boiling and chlorine leave heavy metals in; chelating tablets clean water of everything.
Heavy metal poisoning comes from polluted water — natural water and snow on Sakhal, and hot springs. The game counts the metal in your body as agents, up to 600; it grows while polluted water is in your stomach, the faster the more of your stomach it fills. The first two stages fade by themselves once your stomach is clean; from 400 agents it never ends without chelating tablets.
Stages
How the disease runs in the game, stage by stage: when it starts, what it does, and whether it still heals.
Early
heals by itself1–199 agents (of 600)
Symptoms
- Getting thirsty unusually fast
You lose an extra ~0.24 water per second, and your hands shake every 20–40 s. No sick icon.
Once no polluted water is left in your stomach it fades with any immune system: ~20 min from the top of this stage, ~3 min with an immune system above ~72 % or multivitamins.
Middle
heals by itself200–399 agents
Symptoms
- Pain groans
- Muffled hearing
- Getting thirsty unusually fast
- Sick icon in the status bar
You keep losing extra water and groan in pain every 20–40 s.
Like the early stage: once your stomach is clean it drops back to the early stage in ~20 min, or in ~3 min with an immune system above ~72 % or multivitamins.
Severe
only with medicinefrom 400 agents
Symptoms
- Muffled hearing
- Ghost images
- Vomiting
- Losing health without being hurt
Your hearing stays muffled and ghost images cross your vision; you vomit every 3–6 min (30 % of your stomach each time). Once it peaks at 600 you lose health.
Never by itself — the poison stays where it is, clean stomach or not. Only chelating tablets bring it down.
Deadly: At its peak (600): ~40–80 min from full health, faster with less blood.
How to get rid of it
Take chelating tablets, one after another as each wears off, until the symptoms are gone. Multivitamins help in the early stages.
How to avoid it
On Sakhal drink from wells and pumps, or put chelating tablets into natural water — boiling and chlorine do not help.
Good to know
- Multivitamins do nothing in the severe stage.
- As long as polluted water is in your stomach the poisoning grows, however strong your immune system is.
- One chelating tablet in a bottle cleans the water of everything, heavy metals included.

The doctor asks what you notice on your character and names the disease and its stage.
