Tunneler. The sandworm can burrow through solid rock at half its burrow speed and leaves a 15-foot-diameter tunnel in its wake that lasts for 1d4 hours before collapsing.
Multiattack. The sandworm makes two attacks: one with its bite and one with its slam.
Slam. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 19 (3d8 + 6) bludgeoning damage. The target hit must also make a DC 19 Constitution saving throw. On a failed save, it is knocked prone and stunned until the end of its next turn. On a successful save, the target is only knocked prone.
Bite. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 12 (1d12 + 6) piercing damage. If the target is Large or smaller size, it must succeed on a DC 19 Dexterity saving throw or be swallowed by the worm. A swallowed creature is blinded and restrained, it has total cover against attacks and other effects outside the worm, and it takes 21 (6d6) acid damage at the start of each of the worm's turns. If the worm takes 30 damage or more on a single turn from a creature inside it, the worm must succeed on a DC 19 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 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 20 feet of movement, exiting prone.
The sandworm, a creature of varying size and lethality that is only found in the deserts of the world and in the lair of the sandworm king. they move around the desert either above ground leaving a trench or by burrowing and creating a "wave" of sand.
