It's just been announced on the World of Warcraft forums that a Warlock with the name Melanie from the realm Vek'nilash has downed Hydross the Unstable in Serpentshrine Cavern solo! After two hours, forty minutes and eight seconds the boss was down, and this has obviously not been done by anyone else at this moment. It's also worth mentioning that the boss did evade after three hours of kiting, and on four procent.
For those who don't know this boss, I can tell that it's the first boss you will encounter at SSC, and has a total of 3.500.000 healthpoints. So in other words, this is a boss that is supposed to be taken by a raid with 25 players, and even then it's a relatively hard fight.
Here is Melanie's armory profile!
