Don't forget, when you leave the area, the device will disappear, whether your departure is intentional or unintentional (running away from a dozen wyrms). You will need to start killing mobs again to get another device if you haven't finished the quest.

As a daily quest, this one is not hard, as long as you don't aggro a bunch of wyrms simultaneously. In addition to the gold, the wyrms drop Apexis shards and motes of mana. Not all bad for 30 minutes' worth of work.
