Spirit impling

The Spirit impling is involved in the Hunter skill. It can be caught in the Impetuous Impulses minigame featuring the impling plane of Puro-Puro and flying around in Gielinor. Catching a Spirit impling grants 227 experience if caught in Puro-Puro, or 321 experience if caught in RuneScape.

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.

Upon jarring the impling, the player can either trade with Elnock Inquisitor or can free the impling from the spirit impling jar, which will leave an item behind. The player can also trade 3 impling jars for one spirit impling.

It is one of the 3 newest types of impling (together with the Zombie implings and Kingly implings) and gathers charms, spirit shards, pouches and other secondary summoning ingredients.

Charms
Charms are looted from the spirit impling, before being placed in a jar, roughly 50% of the time. This means that on average you will receive charms once for every 2 implings you catch. The charms themselves appear to have an equal rarity respective to each other, at 25% chance each.

Other secondary ingredients
Note: The 25 spirit pouch is extremely common, around 7 out of 10 implings are pouches.

Trivia

 * Spirit implings which carry charms are automatically opened on capture, which means that any Spirit Implings bought off other players or from the Grand Exchange will not contain charms. This prevents the 'purchasing' of summoning experience.
 * Most implings say 'Tee hee!' at random times, however, this impling states 'Wheee!' or "*Sigh*" instead.
