Plague

This spell inflicts a virulent, infectious disease on any single creature (if a saving throw versus spell is failed). The target immediately suffers an attack of plague, becoming feverish and disoriented with illness for six turns. During this time, the victim loses 10% of his original hit points, one point each of Strength and Constitution, has -2 penalties to saving throws, attack, and damage rolls, and has a +2 penalty to Armor Class.

All creatures within 10 feet of the victim must make a Constitution check or contract the plague themselves (with the same effects). Creatures currently suffering from the plague cannot contract multiple cases of it and creatures within range of more than one victim need check only once.

When the spell effect expires, a victim is no longer infectious and the penalties end, except that lost hit points and ability scores take 1d6 days to return. Before the last of the plague’s effects wear off, a final Constitution check must be made; if the victim rolls a natural 1 on a 1d20, the victim dies.
