Organ Rejection

This mechanic is off by default. It can be toggled in the Configuration menu.

Organ rejection may occur when a patient receives an organ transplant while their Immunity is higher than 10%. If organ rejection occurs, the organ that was transplanted will immediately gain 100% damage, making it useless.

Reducing Immunity is primarily done using Azathioprine.

At 100% Immunity, the chance for organ rejection is 60%.

Formula:

RejectionChance = (CurrentImmunity - 0.1) / 1.5
