When catching a Kingly Impling without an empty impling jar, you receive the loot instead of obtaining the Kingly Impling Jar.
As can be done with all Impling jars, the Kingly impling jar can be traded in singularly to Elnock Inquisitor for three empty impling jars. This is not recommended, as Kingly impling jars are worth much more than the empty jars. To find out the current profit/loss for trading this impling jar or others in to Elnock use this calculator http://runescape.wikia.com/wiki/Impetuous_Impulses_Jar_trade_calculator
Looting a Kingly impling jar can result in getting any of these items. You should be very careful in buying these, as you are almost guaranteed to lose money. This can be seem to be balanced, however, with the chance to make a very large profit when obtaining an uncut onyx. However, this is not recommended because recent testing (at least on beta) has revealed the chance of getting a onyx to be 1/100 and the average profit/loss is a loss of 250k per jar.

- On the day of release, F2P players could buy both Kingly impling jars and royal crowns in the Grand Exchange. A quick system update rectified this.
