Awakening of the Scion

The cradle is a container for the scion of Skoraeus. When the cradle drops to 0 hit points, its body crumbles to dust. The scion instantly appears in the space the cradle occupied and uses the cradle's initiative count.

If the cradle fails a saving throw, it can choose to succeed instead.

Magic Resistance

The cradle has advantage on saving throws against spells and other magical effects.

Siege Monster

The cradle deals double damage to objects and structures.

Actions

Multiattack

The cradle makes two Slam or Spit Rock attacks.

Slam

Melee Weapon Attack: +15 to hit, reach 20 ft., one target. Hit: 30 (4d10 + 8) bludgeoning damage.

Spit Rock

Ranged Weapon Attack: +15 to hit, range 120 ft., one target. Hit: 24 (3d10 + 8) bludgeoning damage, and the target must succeed on a DC 23 Strength saving throw or have the prone condition.

Shattering Roar (Recharge 5-6)

The cradle lets out a painfully load roar. Each creature within 60 feet of the cradle must make a DC 23 Constitution saving throw. On a failed save, a creature takes 33 (6d10) thunder damage and has the incapacitated condition until the end of its next turn.

Crystal Flare (Bonus Action)

The cradle causes the crystals on its body to flare with light. Each creature within 30 feet of the cradle must succeed on a DC 22 Constitution saving throw or take 21 (6d6) radiant damage and have the blinded condition until the end of the cradle's next turn. Blinded: • A blinded creature can't see and automatically fails any ability check that requires sight. • Attack rolls against the creature have advantage, and the creature's attack rolls have disadvantage.

Stone Spikes (Bonus Action)

The cradle causes the ground in a 20-foot square within 90 feet of itself to sprout crystal spikes until the start of its next turn. The area becomes difficult terrain for the duration. A creature takes 10 (3d6) piercing damage for each 5 feet it moves on this terrain.
