The caster arranges a circle of small fires around the place where the target spirit is (enclosing an area no more than 20 yards across), and, while chanting, burns on them a mixture of rare herbs and mineral. As the casting begins a dark green smoke curls from the fires, enveloping the area in a sweet, olive fog, of damage from the effort. If both a Strength and Constitution check are failed, one point of Constitution is permanently lost.
The mixture of herbs constitutes the material component of the spell. They cost 10 sp if bought in the market, or can be gathered in one day by an individual with the herbalism proficiency.
Notes: Restricted to shamans, uncommon.
