Traits

Awakening of the Scion.

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

Legendary Resistance (5/Day).

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 three Slam or Hurl Lava attacks in any combination.

Slam.

Melee Attack Roll: +17 to hit, reach 20 ft., one target. Hit: 31 (4d10 + 9) bludgeoning damage plus 14 (4d6) fire damage.

Hurl Lava.

Ranged Attack Roll: +17 to hit, range 120 ft., one target. Hit: 27 (4d8 + 9) fire damage. If the target is a creature or a flammable object, it ignites. Until a creature within 5 feet of the fire takes an action to douse the fire, the target takes 10 (3d6) fire damage at the start of each of its turns.

Erupting Breath (Recharge 5-6).

The cradle exhales flames and volcanic gases in a 90-foot cone. Each creature in that area must make a DC 24 Dexterity saving throw. On a failed save, a creature takes 55 (10d10) fire damage and has the poisoned condition for 1 minute. On a successful save, a creature takes half as much damage only.

A creature poisoned in this way can make a DC 24 Constitution saving throw at the end of each of its turns, ending the effect on itself on a success.
