Astral arrow

An arrow with 2 small extradimentional spaces dangerously close to one another. Upon impact, or upon breaking, the two spaces touch, and cause all creatures within 10ft to be pulled into the astral plane, along with anything they are holding or carrying, and the arrow is destroyed.

Simmilarly to arrows of slaying, variants of this exist for other ammunition, such as bolts for crossbows.

These can be crafted by deconstructing 2 extradimentional spaces and with a piece of ammunition of your choosing. When crafting, you must make a DC 8 Arcana check or detonate it early.
