Plague Domain (Best)

Clerics of Plague Domain use illness to fight for the rights of their gods. Whether they see it as a gift or as the curse, those clerics have to learn to use the disease as a hammer against enemies. Whether they will accept this fate or try to fight with this, disease is their strongest weapon.

A lot of them are followers of Talona. Others don't know whence their stigma comes. One is sure. They must hide with their nature in most societies.
