Wondrous item, uncommon
Stern stones always appear as two tan stones, flecked with silver.
Once per day, when a willing creature is physically touching one of the stones, another willing creature touching the other stone can target the other with spells that have a range of touch. They must be on the same plane of existence.
When touching one of the stones, a creature can use a bonus action to change the color of both stones.
