each of which is activated by tracing specific lines on its surface: • A creature can use an action to cast the control weather spell or the divination spell from the stone. Once either spell is cast, this property can’t be used again for 7 days. • A creature can use an action to shrink the stone to the size of a 6-inch-diameter orb weighing 25 pounds, or enlarge the boulder to its normal size (15-foot diameter) and weight (12 tons). Anything the enlarged boulder falls on takes 55 (lOdlO) bludgeoning damage. A creature can avoid taking this damage by tumbling out of the way with a successful DC 15 Dexterity saving throw. Once the reducing or enlarging effect is used, this property can’t be used again for 24 hours.
