The huecambra causes some of the gem-like nodules on its body to detonate. Each creature within 20 feet of the huecambra must make a DC 16 Dexterity saving throw. On a failure, a creature takes 24 (7d6) thunder damage and is stunned until the end of its next turn. On a success, a creature takes half the damage and isn't stunned. A creature cursed by the huecambra's bite has disadvantage on this saving throw.
