One of the interesting and challenging parts of creating Magic Items in tandem with a community on Twitch, is they get inspired by one another as well.
We created three different Banishing-inspired items in one stream, these, the Soul Chain Arrow an the Bow of Banishment.
Banishing Salts
Wondrous Item, very rare
“A small pouch of crushed-up salts, echo-plasm, and other ritually treated materials used for banishing and turning the undead. It can sometimes have unfortunate side effects on the souls of the living as well.”
Banishing salts come in a specially made pouch with 1d4 + 1 handfuls. Using an action you can throw a handful of these salts in a 10-foot cone in front of you. Every creature in the area must make a DC 14 Constitution saving throw or be affected by the magic of the salts.
If the target is an undead, fiend, aberration, or monstrosity and fails the saving throw they are frightened and must spend its turns trying to move as far away from you as it can. It also can’t take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If there’s nowhere to move, the creature can use the Dodge action. This lasts for 1 minute, or until it takes any damage.
For any other type of creature, their soul is banished to a pocket dimension and their body becomes paralyzed. This lasts for 1 minute, or until they take damage.
