When The Devil Calls (Co-Written by Iskawhiskers)

Description:
A silver pouch with the visage of a skull, as well as a collection of prismatic bullets. The pouch can be materialised at any time, be it on their belt, in their hand, or suspended in the air.  The user can retrieve any specific bullet(s) from the pouch as if they were the only bullets inside, as long as they are retrieved from the pouch itself.

Any time the user approaches the location of a death that they are aware of, When The Devil Calls will draw upon the lingering will of the deceased person in question, turning it into a Soul Bullet.  This lingering will can only ever be collected once.  These Soul Bullets can travel to a maximum of 30 metres, are not affected by any form of physics, and will pass through anything that does not contain a soul, but will shatter on any soul-containing entity, disappearing forever as the deceased's lingering will is returned to them in Heaven.  If a Soul Bullet does not hit anything with a soul within 30 metres, it will dissipate, and slowly regenerate inside the pouch over the course of ~30 minutes.

The destructive power of these bullets depends on the strength of the relation between the deceased and the target, both emotional and causal.  A Soul Bullet whose original soul does not relate at all to a target would hit the target with the force of a small gust of wind, where a target that was extremely close with the chosen soul or was a direct cause of their passing could potentially be obliterated.
