From publisher blurb: They stand in defiance where others cannot endure … Scions of faith, eradicators of undeath, Annihilators of the Legion of the Chaos Plague. Do you dare to assume the covenant and mantle of the Mercy Killers, The ultimate expert-difficulty adventurer class within the World of Oldskull? The PLAGUE DOCTOR is a unique, lore-heavy sub-class of the cleric. In addition to details concerning their place in the game world (pertaining to gods of healing, the Black Death, the undead, vermin and wererats, the coming Apocalypse, arcane plagues, and so forth), you will also find rules concerning the surprising combative nature of the class: annihilation of the undead, parrying canes, purging aspergillums, and infestation-destroying alchemical incendiaries. So if you’d like to play a hybrid crusader / healer / mad bomber who looks like a gothic raven of death, you’ve come to the right place! Systems featured in this deluxe class supplement include: plague doctor deity selection, a plethora of level titles and roles, unique spell selections, hospitale stronghold founding, vermin eradication, incendiaries, and an arsenal of equipment, including masks, canes, mantles, and those ever-glorious alchemical explosive vials. So what are you waiting for? Purge the unclean! Purge them all!
