Foul Miasma
You multiply the disease within a creature, drawing it into an infectious mist outside their body where it can spread to other creatures. The target must attempt a Will save. If the target is willing, it can choose to take the effects of critical failure.
Critical Success The target receives the benefit of a successful save against the lowest-level disease affecting it.
Success The target is unaffected.
Failure One randomly chosen disease affecting the target fills the air in a 15-foot emanation centered on the target. For the spell's duration, any creature that enters or ends its turn within the area is exposed to that disease.
Critical Failure As failure, except the miasma contains all the diseases affecting the target.

An action with this trait requires a degree of mental concentration and discipline.
An effect with this trait applies one or more diseases. A disease is typically an affliction.
Focus spells are a special type of spell attained directly from a branch of study, from a deity, or from another specific source. You can learn focus spells only through special class features or feats, rather than choosing them from a spell list. Furthermore, you cast focus spells using a special pool of Focus Points—you can't prepare a focus spell in a spell slot or use your spell slots to cast focus spells; similarly, you can't spend your Focus Points to cast spells that aren't focus spells.
You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
