Void spinner

The Void spinner is a Summoning familiar, introduced with the "Summoning 2" update on 31 March, 2008. It requires level 34 Summoning.

To make a Void Spinner pouch you need to use a empty pouch, a Blue Charm, a Spinner Charm, and 74 Shards on an Obelisk.

Healing
The void spinner will automatically heal one hitpoint approximately every 15 seconds up to a player's maximum. Note that the healing ability still works even if a player does not have any remaining Summoning points.



The healing effect makes the Void Spinner useful in single combat environments as it can restore up to 108 hitpoints over its summoning duration of 27 minutes. This is equivalent to 9 cooked lobsters, although a player could heal much more hp for the same cost by buying the lobsters rather than investing in a spinner familiar. Therefore, it's best application is for when you need healing but also need inventory space for things like monster drops.

Although the Bunyip has a better healing rate than the Void Spinner, the Void Spinner can be useful for the player if he/she doesn't have 68 Summoning.

Trivia
