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 sphere device with multiple deeply set grooves and runes across it.

Properties
The generator fills a space with gently floating arcane motes: small, glowing, bobbing bits. It has no physical effect, but anything that negates magic in that field is easy to spot within its positioning. The effect lasts for one hour, and once activated, the generator cannot be used again until the next dawn. It covers a 100-foot radius.

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.
