Hakkar would cast Corrupted Blood on gamers and it would damage them for about 10 seconds. Players would disperse the Wow gold classic impact to others when they got too close to those infected. After the 10 seconds were done, or players completed the boss battle, the harmful impact was supposed to end. Only it didn't. A programming oversight enabled the debuff to disperse beyond the site of this Hakkar boss fight and to the world at large. Much like rats fueled the Bubonic Plague, personalities' trained animals spurred the Corrupted Blood outbreak. Hunter characters may summon and dismiss pets to fight at their side at will.

There it would spread to other players and buy classic wow gold pets that came in contact with them.
