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.

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

 * Strangely, the imps that create the crop circles cannot be examined, nor do they appear on the minimap.
 * On the update of the 23rd February 2010, along with the new impling update, the blessing which gave you a boost to push through the wheat in Puro Puro faster was named "Farmer's Affinity".
 * Crop circles refer to the belief that aliens leave crop circles when they land in crop fields.
