Niall Ó Glacáin's Plague Doctor Coat

Origin
Niall Ó Glacáin was an Irish plague doctor during the Bubonic plague, treating its victims throughout France, Spain and Italy.

Effects
Originally part of the whole costume set, complete with the beak mask and a cane, this black leather coat became imbued with the sickness and pain felt by Glacain's patents during the black plague. The coat has the unique power to either put a person's illness on hiatus, allowing them to live a normal life or increase the intensity of the sickness, making them suffer greatly.
