Noska Trades' Mass Contagion
(Necromancy)

Range:  5 yards per level
Components:  V, S
Duration:  Permanent
Casting Time:  8
Area of Effect:  One creature per level
Saving Throw:  Negates

This spell causes a major disease and weakness in one or more creatures in the same way as the contagion spell. Up to one creature per experience level of the wizard can be affected, provided that all subject creatures are within the spell range.
The afflicted individual is immediately stricken with painful and distracting symptoms: boils, blotches, lesions, seeping abscesses, and so on. Strength, Dexterity, and Charisma are reduced by 2. Attack rolls are decreased by 2. The effect persists until the character receives a cure disease or spends 1d3 weeks taking a complete rest to recover. Characters ignoring the mass contagion for more than a day or so may be susceptible to worse diseases at the discretion of the DM.
Saving throws against the spell suffer a penalty of -1, and if a single creature is to be affected, its saving throw suffers a -4 penalty.
