This golden necklace has an hourglass, filled with golden dust as its sand, embedded in a gyroscope. The necklace can be used as a spellcasting focus for arcane and druidic casters.

Time Stop. As a reaction when hit by an attack, targeted by a spell, or caught in an Area of Effect, spin the hourglass to freeze yourself in time for 6 seconds. While in this stasis you are encased in gold like a statue and become immune to all effects and damage (ex. Power Word Kill or the breath of a dragon). If a you enter stasis as the result of being targeted by a spell, the spell slot is spent. You exit stasis at the end of your next turn.

Time Stop can be used once, after which the golden dust loses its luster, and recharges every dawn.
