Astra-El Kabong!

The Astral is a Realm of pure creative energy, wherein resides the Dreaming, a place where even mundane objects may possess a ghostly form.

A Way of the Astral Self Monk may use this particular ability to project the Astral Form of a simple weapon onto the Material Plane, creating a number of copies equal to 1+ their proficiency score into each additional Astral arm. Each copy does an additional 1d4+1 bludgeoning damage and has a 20% chance of dealing an additional Astral Flame attack of 1d4 psychic damage.
