Agonizing Aura. The sathaq worm emits ultrasonic noise and minor vibrations that cause pain and subtly disrupt the functions of most creatures. A creature that starts its turn within 15 feet of the sathaq worm must succeed on a DC 17 Constitution saving throw or have disadvantage on attack rolls until the start of its next turn. Creatures with resistance or immunity to thunder damage automatically succeed on the saving throw.
Earth Glide. The sathaq worm can burrow through nonmagical, unworked earth and stone. While doing so, the worm doesn't disturb the material it moves through.
Earthen Camouflage. The sathaq worm has advantage on Dexterity (Stealth) checks made to hide in sandy, muddy, or rocky terrain.
Siege Monster. The sathaq worm deals double damage to objects and structures.
