The Gourmet impling is an impling that can be caught in the Impetuous Impulses minigame, and are located throughout Puro-Puro and Gielinor. The player needs at least 28 Hunter to capture this type of impling.
They could be caught with a butterfly net, magic butterfly net, sacred clay butterfly net, or volatile clay butterfly net.
In Puro-Puro, a net and empty jars are required to catch any implings.
In Gielinor, they can also be caught barehanded or while wielding any item, with or without an empty impling jar. Without an empty jar player will immediately receive the loot from the impling, instead of the impling itself.
Once these requirements have been met the player simply needs to click on the impling, and the character will attempt to catch it, though there is a chance of failure, in which case the character will continue trying to do so until it is caught. Bind, Snare or Entangle could be cast on implings to prevent them from moving for different periods of time.
When the impling is finally jarred the player can either trade with Elnock Inquisitor or can free the Gourmet Impling from the Gourmet impling jar, which will leave an item behind. The player can either get 3 Impling jars for one Gourmet Impling or, with 3 Baby Implings and 2 Young Implings, can get a can of Imp repellant, or alternatively can trade 3 Gourmet Implings with 2 Earth Implings and an Essence Impling to receive a Magic butterfly net. Capturing a Gourmet Impling will grant the player either 82 (if caught on Puro-Puro) or 113 (if caught on RuneScape) Hunter experience.
