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 only permanent crop circle can be found on Zanaris. By entering the centre of a crop circle, a player with a Hunter level of 17 or higher will be teleported to Puro-Puro, where they can participate in the Impetuous Impulses minigame.

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

If the player accesses Puro-Puro by stepping through one of the gates that roam the overworld, they will gain the Farmer's Affinity bonus for a period of 30 minutes. This effect will grant faster passage when pushing through the rows of magical wheat that form the maze, which can be of great benefit when chasing after implings.

The wheat field that contains the crop circle through which the player enters Puro-Puro will be the same field the player returns to after leaving Puro-Puro. The player will return to the field they entered from even if the crop circle has moved on to another location in the meantime.

To determine where the roaming crop circle is currently located, simply visit the Wandering impling in the Zanaris wheat field, who will provide a brief glance at the gate's present whereabouts.

A permanent gate to Puro-Puro can be found on Zanaris, in the form of a quiet crop circle which will never stray from the fairy realm's central wheat field.

A fickle crop circle that nimbly roams the surface of Gielinor provides only temporary access to the impling home plane, before wandering off to the next spot according to a fixed rotation:
