Killing Fire Beetles  

This Quest doesn't exist anymore. Can't alla upgrade things and clear info for non existant quests?

The Klicknik Mite's spawn north of the Aqueduct outside the North Qeynos gate. They are the only aggro mobs in the area surrounded by hawks and snakes.

You do not get an update on every kill, so you will have to kill more than 20.

The recommended level is 10 for this quest. Most people will have already completed their level 9 class change quest. Class change quests give out class specific chest armor which is better than what this quest offers. So odds are you'll end up selling the rewards from this quest.
