Wotlk:Zombie Explosion

By now you must know that it is inevitable. The zombies are here and they are growing in number. In time, you too shall become one of the Scourge, and Azeroth shall feel the icy tendrils of the Lich King's will. There are quite a number of ways to serve the Lich King, but by far the most insidious and shows the most loyalty is the self-sacrifice of a minion to Zombie Explosion!. If you are but to do one thing for the Lord Arthas, it is this. Explode and infect the world around you.

It's important to know that You're Infected!, the disease that turns unwitting players into subservient members of the Scourge, now has a 2 1 minute duration. This is a mere fifth tenth of the original duration and gives players very little time to rid themselves of the infection. The radius of Zombie Explosion! has also been increased greatly, allowing you, for example, to explode inside Orgrimmar's Auction House and infecting everyone inside it. Use this spell in Auction Houses, Banks, and in front of heavily crowded Mailboxes for optimum effect.

The best way to wreak as much havoc is to quietly get infected (you can kill a Plagued Roach or click on a Conspicuous Crate), and situate yourself in a densely populated area. Some players will try to rid you of the disease, so be wary of Priests, Paladins, and Shamans. The moment you turn, start casting Zombie Explosion!. Don't bother with anything else. It is a four second cast spell, with pushback extending that to five, so you must try to get it off as quickly as possible. There is nothing subtle about this ability... it is simple, it is devious, and best of all, you explode in a symphony of rotting body parts and noxious green gas. All hail the Lich King!
