Traits

Tunneler. The Adult Sonari Worm can burrow through solid rock at half of its burrow speed and leaves a 15-foot-diameter tunnel in its wake.

Actions

Multiattack. The Adult Sonari Worm makes two bite attacks and a constrict attack.

Bite. Melee Weapon Attack: +13 to hit, reach 15 ft., one target. Hit: 34 (5d8 + 12) piercing damage. If the target is a Large or smaller creature, it must succeed on a DC 16 Dexterity saving throw or be swallowed by the worm. A swallowed creature is blindedprone, and restrained. It has total cover against attacks and other effects outside the worm, and it takes 21 (4d6) acid damage at the start of each of the worm's turns.

If the worm takes 25 damage or more on a single turn from a creature inside it, the worm must succeed on a DC 22 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 15 feet of the worm. If the worm dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 30 feet of movement, exiting prone.

Constrict. Melee Weapon Attack: +12 to hit, reach 10 ft., any Large or smaller creatures within 10 ft. of the Adult Sonari Worm. Hit: 20 (4d6 + 6) bludgeoning damage plus 20 (3d8 + 7) slashing damage. The target is grappled (escape DC 17) and the target is blinded until this grapple ends. The Adult Sonari Worm may not burrow while grappling a creature.

Bonus Actions

Sand Blast. If the Young Sonari Worm uses its full burrowing speed, it sprays a line of sand that is 30 feet long and 10 feet wide. Each creature in that line must make a DC 116 Dexterity saving throw, taking 33 (6d10) piercing damage on a failed save, or half as much damage on a successful one. On a failed save, creatures must make a DC 14 Constitution saving throw, or gain disadvantage on ability checks and attack rolls until the end of their next turn.
