corrupted-blood

Your mission

Return the first row of the city grid holding at least a given number of infected players.

today's brief

September 2005. Blizzard adds a boss to World of Warcraft whose debuff, Corrupted Blood, jumps to anyone standing close and ticks away until it kills them. It was supposed to stay inside the raid. Hunter pets carried it out through the loading screen into Ironforge, where it killed low level characters faster than they could walk back from the graveyard. Epidemiologists later wrote papers about it.
