Void ravager

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

The Void ravager is not commonly used for combat due to its low maximum hit.

Void ravager pouch
A Void ravager pouch is made by using a Summoning pouch on a Summoning obelisk with 74 spirit shards, a green charm and a Ravager charm in the inventory. Making the pouch earns 59.6 experience points. Using the pouch to summon a Void ravager gains 0.7 experience points. The Ravager charm can only be obtained through the Pest Control activity.

Call to arms scroll
Call to arms scroll enables the use of the Call to Arms special move for Void ravagers, Void shifters, Void spinners and Void torchers. Using the familiar's pouches on a Summoning obelisk creates 10 scrolls. Using the scroll costs 3 special move points.

This move teleports you to the pest control landers.
