Multiattack. The scion makes one attack using Cloud Morningstar or Wind Javelin, as well as two Slam attacks.

Cloud Morningstar. Melee Weapon Attack: +18 to hit, reach 30 ft., one target. Hit: 32 (4d10 + 10) force damage plus 22 (4d10) thunder damage.

Wind Javelin. Ranged Weapon Attack: +18 to hit, range 120/480 ft., one target. Hit: 42 (5d12 + 10) thunder damage, and the target must succeed on a DC 26 Strength saving throw or have the prone condition.

Slam. Melee Weapon Attack: +18 to hit, reach 20 ft., one target. Hit: 28 (4d8 + 10) force damage.

Thunderous Vortex (Recharge 5–6). The scion magically creates a vortex of wind in a 60-foot-radius sphere centered on a point it can see within 120 feet of itself. Each creature in the sphere must succeed on a DC 24 Strength saving throw or be pulled straight toward the sphere's center, ending in an unoccupied space as close as possible to the center. Then a burst of thunder erupts in a 30-foot-radius sphere centered on the same point. Each creature in that area takes 52 (8d12) thunder damage and must succeed on a DC 24 Constitution saving throw or have the stunned condition until the end of its next turn.

Fog of Deception. The scion conjures a magical cloud that fills a 30-foot-radius sphere centered on a point it can see within 90 feet of itself. Each creature in that area must make a DC 24 Wisdom saving throw. On a failed save, a creature has the charmed condition until the end of its next turn. While it has the charmed condition, the creature must use its action to make a melee attack against a creature other than itself of the scion's choice. If no creature is within its reach, the affected creature makes a ranged attack against a creature of the scion's choice, throwing its weapon if necessary. On a successful save, a creature is immune to the scion's Fog of Deception for the next 24 hours.
