Traits
Tunneler. The worm can burrow through solid rock at half its burrow speed and leaves a 10-foot-diameter tunnel in its wake.
Natural Armor. The worm possesses plates of armor made of hard wood which quickly become brittle when exposed to fire.
If the worm takes 10 or more fire damage on a single turn, it must succeed on a DC 23 Constitution saving throw at the end of that turn or have its armor class reduced by 2 for the rest of combat.
Actions
Bite. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 18 (2d8 + 9) piercing damage.
Reactions
Upon having a segment of its shell break it will attempt to burrow, prompting an attack of opportunity.
