Crop circle

Crop circles can be found in some wheat fields and are created when an imp appears and starts walking around in a circle within the wheat field. Most are temporary, appearing for around 15 minutes and then disappearing. The sole permanent crop circle can be found in Zanaris. Crop circles provide the means for Hunters with a level 17 or higher to teleport to Puro-Puro for the minigame Impetuous Impulses. The minigame unlocks the music track "Impetuous".

When a player nears an active crop circle, the game music changes to variation of "Impetuous". The actual notation of unlocking the song will not be reflected on the music interface until the player actually travels to Puro-Puro.

If a player enters Puro-Puro through a crop circle outside of Zanaris, the player will receive a 30 minute blessing which will give them the ability to pass through wheat in Puro-Puro faster. The remaining blessing time is displayed near the upper-righthand corner of the gamescreen, next to the mini-map. This was introduced on 23 February 2010 and is called the Farmer's Affinity Bonus.

Also, it should be noted that the wheat field that contained the crop circle with which you entered Puro-Puro, will also be the wheat field that you will be teleported back to when you leave Puro-Puro. This will happen even if the crop circle has disappeared.

Trivia

 * Crop circles refer to the belief that aliens leave crop circles when they land in crop fields.
 * There is also a belief that a crop circle is an ancient language used by aliens.
 * When passing through the wheat when it is about to shrink into the ground, when you are halfway through you will stop and the text "The wheat here seems unusually stubborn. You cannot push through." appears.
 * When a crop circle disappears, an impling may try to get through it before it leaves. If it doesn't make it, it will shout "Impulus impling brothers!"
