Ball of Containing

This magically inscribed metal ball contains a button on the front of it.  When used against a willing creature with an action, it will magically teleport into the ball and be in stasis.  The creature requires no food, air, or water and will stay in stasis until summoned using an action.

If used against an unwilling creature, the creature must make a Charisma 13 DC, on failure, the creature is teleported into the ball.  It is able to make charisma saving throws on each of its turns to break out.  When not in combat, the creature is able to try to break free every 10 minutes.
