Virulent Cloud

Virulent cloud [minor] by Iczer

'Choke on this'

The character unleashes a cloud around himself for 30 feet +5 feet per level in all directions. Everyone in this cloud suffers from slight visual impairment (-1 to strike, parry and dodge) and suffers from its harsh smell and taste (-2 initiative. The character is immune to the smell aspect at any rate).
The cloud also hampers the body's ability to fight off illness and infection. Everyone within the radius of the cloud suffers a -4 to all saving throws involving poison, disease, magic, or any other saving throw that is augmented by the PE attribute). Once a target leaves this cloud, he may make a saving throw (14+ PE bonuses apply). If successful, the effect ends. Otherwise he remains vulnerable for another 1D4 melee rounds.
The character can choose to lock this cloud onto an area (duration is 1d4+1 melee rounds) or can have it project from himself (requires one action per round to maintain). At any rate it requires 2 melee actions to create the cloud.
