A programming oversight allowed the debuff to spread beyond the website of classic wow gold this Hakkar boss fight and to the world at large. Much like rats fueled the Bubonic Plague, characters' trained creatures lacked the Corrupted Blood outbreak. Hunter characters may summon and dismiss pets to fight in their side at will. Once dismissed, all of the consequences on the pets are paused until it's called back . In consequence, the critters would contract Corrupted Blood during the boss fight, disappear and then display the symptoms elsewhere in the world map if they were summoned. There it might spread to other pets and players that came in contact with them.
Cities like the dwarven town Ironforge and orc city Orgrimmar were overrun in hours. Non-playable characters, who couldn't die due to particular coding, would also capture the consequence, meaning any participant who passed by them could receive Corrupted Blood.
After word got out, players searched frantically for news about what was going on.
"The entire world chat would burst any time a city dropped," says Nadia Heller, an ex-World of Warcraft player whose character lived through the episode. "We kept a close eye not only on our guild conversation but on world chat as well to see where not to go. We didn't need to grab it."
The spread of Corrupted Blood, and the participant's behavioral changes to it, caught the interest of epidemiologist Dr. Nina Fefferman, who had been a cheap wow gold classic player at the time of this incident. In 2007, the two released a paper that detailed their findings, such as complicated models of individual behavior in a pandemic. Fefferman says the incident has helped inform her current research into predictive modeling around covid-19.
