Contagious Fog

Conjuration (Creation)
Level: Sorcerer/wizard 3
Components: V, S, M
Range: Medium (100 ft. + 10 ft./level)
Duration: 1 round/level
Saving Throw: See text

Throw out your arm, and a brown mist
whirls into being around your foes.

This spell functions like fog cloud (PH
232), except as noted here. Each round
that a creature is within the fog, it must
make a Fortitude save or contract a disease
equivalent to the shakes (DMG 292),
which strikes immediately (no incubation
period). A creature affl icted with
this disease takes 1d8 points of Dexterity
damage immediately, and each day that
the disease persists, it must make a DC
13 Fortitude save or take another 1d8
points of Dexterity damage.

The fog moves away from you at 10
feet per round, rolling along the surface
of the ground or water. (Figure out the
cloud’s new spread each round based on
its new center, which is 10 feet farther
away from the point of origin where
you cast the spell.) Because the vapors
are heavier than air, they sink to the
lowest level of the surface over which
they move, pouring down sinkhole
openings, and even down through
minute cracks. Contagious fog cannot
penetrate liquids, nor can it be cast

Material Component: A used handkerchief.
