Vipe-out!

Vipe-out! is a kill quest given by Argent. It requires killing a Boss mob.

How To Achieve
Viper is located within caves, but usually of a deeper level than his weaker cousins, the Netherdrakes. When encountered and you are of low-level, it is best to try and stay away from the Netherdragon for now since its poison is long lasting and very dangerous. Once immune to poison, though, Viper is very easy to deal with, even simply attacking him with a sword is much better than with a bow.

Once defeated, return to Argent and talk to her to finish the quest.
