This Carrion Tribe reveres an imprisoned force of filth and pestilence. Its members seek to turn the power of their lord against their enemies. Plaguebearers smear their weapons with dung; a victim struck with a coated weapon must succeed on a DC 12 Fortitude saving throw or fall victim to filth fever (incubation 1d3 days, damage 1d3 Dex and 1d3 Con). Plaguebearers are typically covered with weeping open sores and angry welts from various infections, but they are remarkably resistant to the effects of diseases and poisons.
In battle, the Plaguebearers become wild berserkers; they close ranks as quickly as possible and fight to the death, praying that infection will claim the lives of any enemies who survive the battle. Fulgrun Bloodboil (CE male human half-fiend, barbarian 11), a hideous individual surrounded by a horrible stench of pus and rot, leads the clan.

While some clans conduct diplomacy and trade, the Plaguebearers are left in reviled isolation. Their open sores and wasted skin are omens of the danger they pose, for the tribe harbors disease within themselves as weaponry.
