Stone of the Earth Spirit

Wondrous item, uncommon

As an action three times per day you can use the stone to cast minor illusion (spell save DC 14). You can only use the spell to create a sound and not an image. The sound must emanate from the stone. If you are carrying the idol, an earth elemental or giant who tries to target you with a weapon attack must succeed on a DC 14 Charisma saving throw or choose another creature as its target instead. If it succeeds on the saving throw, it is immune to this effect until the next dawn. If you hold the idol in both hands, the elemental or giant has disadvantage on this saving throw.
