Plague Priest is a Skaven melee infantry unit in Total War: Warhammer II. The Harbinger of Disease guides their actions, blighting enemies with pus, pestilence, and scourge. He is of the Wizard Hero type, though a more than decent melee combatant, unlike most heroes of that class. He's a part of the Sorcerer Skaven Hero class, along with the Eshin Sorcerer.
Plague Priests are the most degenerate ratmen of the Disciples of Decay, otherwise known as Clan Pestilens. They lead their foul brethren in the creation of new and virulent diseases - forever searching for the ultimate plague that can weaken all nations so that the Skaven can rise up and rule supreme. The Plague Priests claim the great Harbinger of Disease himself, the Horned Rat, grants them sorcerous powers to aid their unholy mission. Whether their arcane might is granted by a divine presence or from long study of the Book of Woe, there is no denying the noxious powers of the Plague Priests. Vomiting geysers of black death or cursing the enemy from afar so that he erupts with blistering boils. Plague Priests wield loathsome, but potent magics. When the outcome of a battle has particular importance to Clan Pestilens, the Plague Priest may even sanction the building of a great Plague Furnace to accompany the brotherhood on their divine mission to destroy all those who oppose them.
↑Armour-Piercing: The damage of armour-piercing weapons mostly ignores the armour of the target, making them the ideal choice against heavily-armoured enemies. They are often heavier and attack at a slower rate though, making them less efficient against poorly-armoured targets.
↑Frenzy: Units with frenzy cause more damage while their leadership is high.
↑Plague Censer: Warpstone dust and vile contagions fill this diabolical censer, exposure to which does horrendous things to bodies and minds alike.
Plague Furnace. Putting him on this mount increases his missile resistance to 25% and grants him a 25% magic resistance too, as well as access to the Billowing Death ability, and gets him the Siege Attacker trait. It also makes the Plague Priest Anti-Infantry, and naturally unable to hide in forests.
