Cities like the dwarven city Ironforge and wow gold classic orc town Orgrimmar were overrun in hours. Non-playable characters, who could not die as a result of particular coding, could also catch the impact, meaning any participant who passed them could receive Corrupted Blood.
After word got out, players hunted frantically for news about what was going on.
"The world chat would explode any time a city fell," says Nadia Heller, an ex-World of Warcraft player whose persona lived through the incident. "We kept a close attention not only on our guild chat but on earth chat too to determine where not to proceed. We did not want to catch it."
The spread of Corrupted Blood, and the participant's behavioral changes to this, captured the attention of epidemiologist Dr. Nina Fefferman, who was a World of Warcraft player in the time of the episode. Fefferman reached out to her colleague Dr. Eric Lofgren. In 2007, the two published a paper that detailed their findings, such as complicated models of individual behaviour during a pandemic. Fefferman claims the incident has helped inform her current research into cheap wow classic gold predictive modeling around covid-19.
