Stasis Stone

Wondrous item, very rare

This small, crystalline, purple stone measures 3/4 of an inch in diameter and weighs an ounce. Typically, 1d4 + 2 stasis stones can be found together.

You can use an action to throw the stone up to 30 feet. The stone explodes on impact and is destroyed.

Each creature within a 10-foot radius of where the stone landed must succeed on a DC 15 Constitution saving throw or be petrified until the end of its next turn as the stone releases temporal magic and freezes it in time.
