Druid, thy poisons are quick and subtle.

HEMLOCK TOUCH

School conjuration [creation]; Level druid 3, witch 3

Casting Time 1 standard action

Components V, S

Range touch

Target creature touched

Duration 1d3 days

Saving Throw Fortitude negates; Spell Resistance yes

Flowering hemlock buds take root in the target's skin, growing from the living flesh and infusing the target's body with subtle poison.  The target takes 1d3 points of Constitution damage and is sickened. If the target is subject to an effect that would render it sickened, it becomes nauseated instead.

Special: The hemlock growing from the target is perfectly viable and can be harvested to produce poison. The DC for hemlock poison harvested from the hemlock this spell creates is equal to the save DC of this spell.
