A person afflicted with radiation suffers a most peculiar fate. At first, it will appear as it they are fine, as nothing will happen immediately. As battle rounds pass, however, the person may start coughing or groaning in pain - the radiation has begun to take effect. Eventually, the subject will die as the radiation becomes too strong for their body to handle. Often upon death, the affected victim's body will lose its composition, causing its mass and internals to fall to the ground in a horrific sight. Only spells may cure radiation, as it never wears off on its own.
The death effect of someone dying by radiation was influenced from Fallout 2's death by Plasma weapons.
