Void torcher pouch is made by using a blank pouch with 74 spirit shards, a blue charm, and a torcher charm in the inventory at a summoning obelisk. Making the pouch earns 59.6 experience points. Using the pouch to summon a Void torcher gains 0.7 experience points, and costs 40 Summoning points.
Call to arms is the special move for Void familiars, which teleports the player directly to the Void Knights' Outpost. Activating this move will cost the player 3 special move points.

Making a void torcher 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 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 torcher's chat line "'T' is for torcher, that's good enough for me" is a reference to the character Cookie Monster on the popular children's show Sesame Street.
Prior to the Evolution of Combat, the Void torcher had a special right-click ability, Strike, that caused it to attack instantly, inflicting 10 points of extra damage. This ability drained Summoning points each time it is used. This has since been changed into a slightly different version of its basic attack that is used randomly.
