Arcane Field Generator

An  is a magical item that when activated reveals the existence and limits of an antimagic field.

Appearance
The generator is a circular spherical device with multiple deeply set grooves and runes across it.

Properties
The generator fills a space with a 100-foot radius with gently floating arcane motes: small, glowing, bobbing bits that shed low light within the affected area. The motes have no physical effect, but anything that negates magic in the field is easy to spot within it. The effect lasts for one hour, requires an action to activate, and once activated, the generator cannot be used again until the next dawn. Each time it is used, it has a chance of becoming inert permanently.

History
Allura Vysoren acquired two generators from "friends in Vasselheim" who hunted beholders with them. She loaned them to the Mighty Nein for use in their effort to combat Lucien.
