Void shifter

The void shifter is a level 34 Summoning familiar. It requires 1 blue charm, 1 shifter charm, and 74 spirit shards. It also provides Attack experience when fighting in combat. The ability closely resembles the ring of life as it teleports you to the Void Knight Outpost if you are below 10% of your maximum life points. Some people purposely activate its special ability by lowering their LP to quickly get to the Void Knight Outpost, once there, they join a game and their LP is regained.

Trivia

 * Making a void shifter pouch gives little experience. Giant chinchompa pouches requires a lower Summoning level, also uses blue charms but gives over four times as much experience. This may be an oversight on Jagex's part, as all void familiars' pouches give the same experience when made, but the void ravager uses a green charm rather than a blue charm, and the xp it gives fits well between the beaver and macaw pouches, which are the ones flanking it in terms of Summoning level required among the green charm familiars.
 * The void shifter's dialogue shows a stereotypical British accent.
 * The untranslated speech of the void shifter are actually quotes from Moby Dick.
