Embitter

Embitter: [Major] by Iczer

'Choke on this!'

The character can cause a target to excrete a volitile substance, making targets sick and vulnerable. By touching an object, that object begins to 'sweat' a pale blue fluid like sheen that persists for 2 minutes before dissolving in air. This sheen is reactive to force and if struck during this time by any physical blow (as well as any source of heat) the object takes an additional 4D6 damage as the fluid explodes(+2 per level). Targets affected by this can be of any size, but the sheen covers an area about 4 feet across.
Touching a person with this has more dangerous results. A touched target must make a saving throw vs poison (non lethal) or become sick as the fluid invades his blood and pervades his body. A sick target loses one attack per melee, -2 from all combat rolls and -15% to all skills for 2 melee rounds per level. Furthermore, any damage taken while sick causes the fluid to react, adding +2D6 damage. Unlike with physical objects, the fluid is not burnt out when ignited, but pockets remain in the body for the entire duration.
A person infected with this is 'poisoned'. Creatures immune or resistant to poison are required to make the normal saving throws, but are not sickened by it (or are sickened to a lesser degree in the case of resistant) they enjoy a halved duration, and the only side effects are the extra vulnerability to damage (which is also halved).
The character can brew this substance within himself making him mildly toxic. If he bites or scratches (or spits in an open wound), the target must make a saving throw vs non lethal poison or become sick for a single round. Furthermore, anyone biting him must make the same saving throw or become sick for the round.

Other bonuses:

The character is resistant to poison and toxins (half effect and +4 to saving throws)

+4D6 SDC
