About: The Diseased One's blossoming inner corruption has overwhelmed his immune system: he is a breeding ground for every imaginable plague. An ordinary man afflicted with a tenth of the Diseased One's maladies would be dead within the hour. Yet he has learned to draw just enough vital energy from his corruption to stave off death, and so he lives in a nightmarish twilight of fevered delusions, racking pains, and his desperate, scrabbling will to live.
Lurching about the field like a drunken man, the Diseased One is a clumsy fighter at best; it is not difficult to end his tortured existence. However, as he expires, his body explodes from the sudden internal pressures of rot and decay, spreading pestilence across a wide area.
Usage: My Second Chance tactic requires extensive use of these units. 25% - 30% of my army are diseased. Thus, they play a major role in battle. Ronin and Samurai fall before them like a pack of cards, and they wreak a lot of havoc.
I keep a Diseased near my Rice with his Death Wail BG. When Koril pops up, I wail his stamina away and kill him with the Diseased and other backup. That way, he cannot retreat home.
Diseased are ideal for stopping Fan Geisha armies, as they have Death Wail to sap their stamina, and are resistant to cutting. I have not tried the Projectile Vomit much, except that it acts like his rotting decay without him dying.
