Stasis sphere

The stasis sphere was a magical item. When touched by its owner and commanded, one nearby creature may be placed in temporal stasis and confined inside the sphere. (Similar to imprisonment spell)

Description
The sphere was a greenish and glowing sphere crystal-made and around 8 feet diameter. Inside the sphere there was an extradimensional space in which as many as fifty creatures may be confined. With a second command a creature may be freed. Once the sphere has been used fifty times, it can no longer restrict new creatures.

History
It was used by Telkoun Adranther in the Telkoun's Tower for his creepy experiments.
