Epidemius is Nurgle's chosen Tallyman, one of the seven Proctors of Pestilence and the cataloguer of all the Plaguelord's diseases. Epidemius' task is an unending one, and it generates a great deal of paperwork, so he rides a palanquin to share the burden - and to more easily force a path through Nurgle's hordes.
Epidemius has a Toughness of 6 and 2 Wounds. Additionally, the Palanquin he rides upon gives him another wound for a total of 3. He has the Poisoned Attacks rule which can ignore most armor saves.
