Foul Humour
The wraith may channel his Corpus through the Shroud, manifesting noxious substances or swarms of small vermin. He can create plagues of frogs or locusts, clouds of wasps, or nests of snakes, rats or spiders. He can alternatively produce clotted gore, raw flesh, blood, muck, reasonably strong acid or other foul matter.
System: The player must state what effect he is trying for and roll Intelligence + Pandemonium. The number of successes determines the extent and detail of the manifestation. The substances or vermin usually vanish after a scene or less; traces infrequently remain, particularly if the wraith scored five or more successes. Any caustic or damaging effects inflict one die of damage for every two successes on the initial roll.
This art costs 1 Pathos and 1 Willpower, and grants the wraith a point of Angst.
