The soul-in-a-box is an item that can be manufactured using the Invention skill. It requires level 24 Invention to discover. The blueprint is used to discover how to make a soul-in-a-box, which is a reward from Nomad's Elegy. Once made, it is reusable and can be activated to summon a Distracting Soul that aids in pickpocketing. Each Distracting Soul costs 100 charges from the charge pack and lasts for 1 minute. Players may only summon one soul at a time.
If powering a charge pack with a divine charge, 30 distracting souls can be summoned per divine charge which gives an average cost of 2,711.8 coins per soul summoned when charges are bought from the Grand Exchange.
