A wondrous item. It can be used as a spell focus. It requires attunement.
Description
A misty, rounded blue jewel of decent size that seems to swirl and mix a glittering liquid around in its center. Occasionally, voices can be heard coming from the gem.
Effects
Certain conditions must be filled to utilize the Soulcaster’s properties. Firstly, the user must attune to the item by studying it for a period of 10 hours. Secondly, it must contain the soul of at least one dead creature.
Once its conditions are fulfilled, the Soulcaster provides a +1 bonus to spell attack and damage rolls. Additionally, a spell may be stored within the orb that the caster knows to be utilized at a later time. Storing a 1st level spell will require one soul to be held within the orb, but higher level spells will increase the soul requirement by a factor of 2, meaning that a 2nd level spell will require 2 souls, a 3rd will require 4, and so on. When a spell is cast by using the gem as an action, these souls are consumed.
The gem has a weak binding force that attempts to grab any free souls in a 30 foot radius, while it is attuned. This force can be overridden by other soul-specific magic. As an action, the user may release any number of souls they wish from the gem.
An individual who is not attuned to the Soulcaster may smash the gem to release the spell currently stored inside, alongside any unused souls.
