Astral Gyrojet: A Gyrojet round filled with FAB II. When shot at a dematerialized spirit it causes a forced astral interaction as it passes through the spirit.
Astral Shells: Shotgun shells replacing shot with the seeds of a duel natured plant (super bonus points if you find an awakened ironwood tree).
Panic Button: For those groups that need conference area's that are astrally secure but don't want to kill somebody who becomes accidentally trapped in an Astral Form, these are small boxes filled with FAB I. A trapped astral entity can reach inside of one causing the fab to flores. This either causes a door to open or signals security to send somebody up.
Astral Ink. Digital paper with a light coating of Fab on one side of the sphere (digital ink works by having one side of a pixil sphere coated white the other black and electomegnetically turning the sphere over).
Astral Paint. Uses a version of FAB mixed in with paint. This is not enough to create a barrier (and will die in a couple months) but can be used to paint a sign in the Astral (because no space should be advertising free).
Spirit pet. A Force 1 or Force 2 animal spirit bound to long term service using a "charge" (a written set of instructions describing a service in detail, covering most common situations read by the summoner to the spirit upon binding it) to serve is a pet/service animal. Most often used to police/rescue spirits or other form of handycapped service spirits (and rarely). One or two may also be serving as actual pets. There are a somewhat higher than normal instances of these spirits remaining after their term of binding is up. For a low force dog spirit sticking around as a pet/rescue animal doesn't always seem like such a bad idea.
