The Quick as the Wind event lasts for 30 minutes during that time you will need to locate the Agent of Wind, who can be at one of three locations: Etherblade (438, 886), City of the Plume (334, 428), or City of the Lost (254, 641). Next, you'll have to accept his quest to kill a boss associated with the city he appears at. These bosses aren't terribly difficult, but speed is what matters!
Once the boss is killed, you'll be awarded two items: a Sealed Wraith Essence and a token of the slain boss. The Agent of Wind accepts the tokens while the Agent of Thunder accepts the Sealed Wraith Essences. Every player will receive rewards for turning in the token, however only the first 99 players to turn in the essences will receive a reward! There will be system messages that go off when 9, 29, 49, 69, and 89 essences have been turned in.
The event ends when either 99 players have turned in Sealed Wraith Essences or the full 30 minutes have elapsed since the Agent of Wind appeared. If you have a team ready to tackle this event, you'll most likely come out on top as being able to know where to go will be of utmost importance!
