A hemolytic reaction is your body fighting blood of the wrong type. It is no infection, so nothing grows or spreads: it starts when a transfusion with more than 175 ml of wrong blood ends, drains blood for a fixed time and then stops by itself.
Stages
How the disease runs in the game, stage by stage: when it starts, what it does, and whether it still heals.
Reaction

Symptoms
- Passing out
- Losing blood without bleeding
- Sick icon in the status bar
You lose 7 blood per second for ~2.8 min — ~1170 in total. Sick icon.
Ends by itself after ~2.8 min.
How to get rid of it
Wait it out; a saline drip makes up for part of the loss. Then let your blood regenerate.
How to avoid it
Test both blood types with a blood test kit first; O negative is safe for everyone.
Good to know
- More than 75 ml of wrong blood already knocks you out when the transfusion ends.
- Wrong blood adds nothing to your blood — the bag is wasted.
- Germs in the bag reach you either way, matching blood or not.
- 0− blood suits everyone, and AB+ can take every type. Test with a blood test kit first.
